Ah, did not see your follow up. Thanks. Chris On Thu, 30 Nov 2006, Cindy Swearingen wrote: Sorry, Bart, is correct: If new_device is not specified, it defaults to old_device. This form of replacement is useful after an existing disk has failed and has been physically replaced. In this case, the new disk may have the same /dev/dsk path as the old device, even though it is actu- ally a different disk.

[zfs-discuss] growing vdev or zfs volume
I was wondering, if I have vdev setup and I do present it to another box via iscsi, is there any way to grow that vdev? for example when I do this: zfs create -V 100G mypool6/v1 zfs set shareiscsi=on mypool6/v1 can I then expand 100G pool to lets say 150G? I do not care about file system on the other end, I was just wondering if it works like SAN where I can change LUN size on a fly to whatever I want to depending on the needs... Yes I know, I can create mypool6/v2 which is 50G and then add it to pool on the other side, but I do not want to go this route. How about if I have SAN presented disk to my solaris server and I do increase it from 100G to 150G, can I update zfs somehoe to see it? I did run that and when I did issue format I was able to see my disk changed sice but when I did go to view partition I was seeing it as 100G only and no extra space available. Under UFS I had issues with such operations and usualy my UFS partitions were destroyed. On my Windows servers I can change drive geometry (add more space) and windows will recognize it... WOnder that do you think or is there any sollutions. Reason why I want to do this is to reduce amount of volumes/pools/luns that I have in my environment. Ah, yeah I can also replace smaller disk with larger disk, I did that in the past by creating temporary mirror and then removing disk from that mirror, virtually replacing disk with larger disk.. but as I said, on windows its handled so much better and I was seriously wondering if zfs gave us similar easy tools of expanding pools in this way.

It is kind of work around but sucks that there is no easy way of getting it rather than going around this way. and format -e, changing label on that disk did not help, I even recreated partition table and I did make a huge file, I was trying to dd to that disk hoping it would overwrite any zfs info, but I was unable to do any of that... so my work around trick did work and I have one extra disk to go, just need to buy it as I am short on one disk at this moment.

Re: [zfs-discuss] migrating ufs to zfs - cant boot system
Yes, I did notice that error too, but when I did lustatus it did show as it was
ok, so I guess I did asume it was safe to start from it, but even booting up
from original disk caused problems and I was unable to boot my system...
ANyway I did poweroff my system for few minutes, and then started it up and it
did boot without any problems to original disk, I just had to do hard reset on
the box for some reason.

[zfs-discuss] ufs to zfs root file system migration
I did upgrade my Solaris and wanted to move from ufs to zfs, I did read about it a little but I am not sure about all the steps... Anyway I do understand that I cannot use whole disk as zpool, so I cannot use c1t1d0 but I do have to use c1t1d0s0 instead is that correct? also all documents that I've found say how to use LU to do this task, but I was wondering how can I do my migration when I have few partitions. Those are my partitions: /dev/dsk/c1t0d0s016524410 11581246 477792071%/ /dev/dsk/c1t0d0s616524410 9073610 728555656%/usr /dev/dsk/c1t0d0s116524410 1997555 1436161113%/var /dev/dsk/c1t0d0s781287957 1230221 79244857 2%/export/home when I create root zpool do I need to create pool for all of those partitions? do I need to format my disk and give my slice s0 all the space? in LU environment how would I specify to move / /usr /var and possibly /export/home to go to that one pool? how about swap and dump pools? I did not see examples or info how that could be acomplished. I would appreciate some hints or maybe there is already someplace document out there, I just was unable to locate it... Greatly appreciate your help in pointing me to the right direction. Regards, Chris ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] ZFS in S10U6 vs openSolaris 05/08
I was hoping that in U5 at least ZFS version 5 would be included but it was not, do you think that will be in U6?

Re: [zfs-discuss] lost zpool when server restarted.
Because this system was in production I had to fairly quickly recover, so I was unable to play much more with it we had to destroy it and recreate new pool and then recover data from tapes. Its a mistery as to why in the middle of a night it rebooted, we could not figure this out and why pool had this problem... so unfortunatelly I will not be able to follow what you Victor and Jeff were suggesting. before we destroyed that pool I did get output of fmdump on that system to see what failed etc. As you can see it happend at around 3:54 am on Sunday morning there was no one on the system from admin perspective to break anything, only thing that I might think of would be the backups running which could generate more traffic, but then I had that system for over a year setup this way, and no changes were made to it from storage perspective. yes I did see this URL: http://www.opensolaris.org/jive/thread.jspa?messageID=220125 but unfortunately I was unable to apply it in my situation as I had no idea what values to apply... :( anyway here is fmdump bash-3.00# fmdump -eV TIME CLASS Apr 27 2008 03:54:05.605369200 ereport.fs.zfs.vdev.open_failed nvlist version: 0 class = ereport.fs.zfs.vdev.open_failed ena = 0x18594234ea1 detector = (embedded nvlist) nvlist version: 0 version = 0x0 scheme = zfs pool = 0x39918ce32491d000 vdev = 0xc40696f31f78fd48 (end detector) pool = mypool pool_guid = 0x39918ce32491d000 pool_context = 1 vdev_guid = 0xc40696f31f78fd48 vdev_type = disk vdev_path = /dev/dsk/emcpower0a parent_guid = 0x39918ce32491d000 parent_type = root prev_state = 0x1 __ttl = 0x1 __tod = 0x4814311d 0x24153370 Apr 27 2008 03:54:05.605369725 ereport.fs.zfs.vdev.open_failed nvlist version: 0 class = ereport.fs.zfs.vdev.open_failed ena = 0x18594234ea1 detector = (embedded nvlist) nvlist version: 0 version = 0x0 scheme = zfs pool = 0x39918ce32491d000 vdev = 0xd56fa2d7686dae8c (end detector) pool = mypool pool_guid = 0x39918ce32491d000 pool_context = 1 vdev_guid = 0xd56fa2d7686dae8c vdev_type = disk vdev_path = /dev/dsk/emcpower2a parent_guid = 0x39918ce32491d000 parent_type = root prev_state = 0x1 __ttl = 0x1 __tod = 0x4814311d 0x2415357d Apr 27 2008 03:54:05.605369225 ereport.fs.zfs.zpool nvlist version: 0 class = ereport.fs.zfs.zpool ena = 0x18594234ea1 detector = (embedded nvlist) nvlist version: 0 version = 0x0 scheme = zfs pool = 0x39918ce32491d000 (end detector) pool = mypool pool_guid = 0x39918ce32491d000 pool_context = 1 __ttl = 0x1 __tod = 0x4814311d 0x24153389 Apr 27 2008 03:56:28.180698100 ereport.fs.zfs.vdev.open_failed nvlist version: 0 class = ereport.fs.zfs.vdev.open_failed ena = 0x398b69181e00401 detector = (embedded nvlist) nvlist version: 0 version = 0x0 scheme = zfs pool = 0x39918ce32491d000 vdev = 0xc40696f31f78fd48 (end detector) pool = mypool pool_guid = 0x39918ce32491d000 pool_context = 1 vdev_guid = 0xc40696f31f78fd48 vdev_type = disk vdev_path = /dev/dsk/emcpower0a parent_guid = 0x39918ce32491d000 parent_type = root prev_state = 0x1 __ttl = 0x1 __tod = 0x481431ac 0xac53bf4 Apr 27 2008 03:56:28.180698375 ereport.fs.zfs.vdev.open_failed nvlist version: 0 class = ereport.fs.zfs.vdev.open_failed ena = 0x398b69181e00401 detector = (embedded nvlist) nvlist version: 0 version = 0x0 scheme = zfs pool = 0x39918ce32491d000 vdev = 0xd56fa2d7686dae8c (end detector) pool = mypool pool_guid = 0x39918ce32491d000 pool_context = 1 vdev_guid = 0xd56fa2d7686dae8c vdev_type = disk vdev_path = /dev/dsk/emcpower2a parent_guid = 0x39918ce32491d000 parent_type = root prev_state = 0x1 __ttl = 0x1 __tod = 0x481431ac 0xac53d07 Apr 27 2008 03:56:28.180698500 ereport.fs.zfs.zpool nvlist version: 0 class = ereport.fs.zfs.zpool ena = 0x398b69181e00401 detector = (embedded nvlist) nvlist version: 0 version = 0x0 scheme = zfs pool = 0x39918ce32491d000 (end detector)

Anyway that is a simple mirror zpool, I would like to create another pool lets say mypool2 with few more disks and use raidz2 instead... What would be my options to do this transfer? I cannot attach to this existing pool disks, I don tthink thats an option because thats mirror and not raidz2... can I create raidz2 and just add it to mypool using zpool add option? and then when its added is there any way to remove originall mirror out of it? Now the tricky part is I have lots of snapshots on that mypool and I would like to keep them... Another option that I think I have is just create mypool2 as I want it to be which is raidz2 and then use zfs send and receive to move data around and then restroy original mirror when I am done replacing it with this one... What do you think? what would you recommend? with the second option I probably would need to take system offline and do it and I dont even if first option would even work where I would just add newly created raidz2 to mypool and then remove original mirror out of it...

ok, I think I did figure out what is the problem well what zpool does for that emc powerpath is it takes parition 0 from disk and is trying to attach it to my pool, so when I added emcpower0a I got the following: bash-3.00# zpool list NAMESIZEUSED AVAILCAP HEALTH ALTROOT mypool 68G 53.1G 14.9G78% ONLINE - mypool2 123M 83.5K123M 0% ONLINE - because my emcpower0a structure looked like this: format verify Primary label contents: Volume name = ascii name = DGC-RAID5-0324 cyl 51198 alt 2 hd 256 sec 16 pcyl= 51200 ncyl= 51198 acyl=2 nhead = 256 nsect = 16 Part TagFlag Cylinders SizeBlocks 0 rootwm 0 -63 128.00MB(64/0/0) 262144 1 swapwu 64 - 127 128.00MB(64/0/0) 262144 2 backupwu 0 - 51197 100.00GB(51198/0/0) 209707008 3 unassignedwm 00 (0/0/0) 0 4 unassignedwm 00 (0/0/0) 0 5 unassignedwm 00 (0/0/0) 0 6usrwm 128 - 51197 99.75GB(51070/0/0) 209182720 7 unassignedwm 00 (0/0/0) 0 So what I did I changed my layout to look like this: Part TagFlag Cylinders SizeBlocks 0 rootwm 0 - 51197 100.00GB(51198/0/0) 209707008 1 swapwu 00 (0/0/0) 0 2 backupwu 0 - 51197 100.00GB(51198/0/0) 209707008 3 unassignedwm 00 (0/0/0) 0 4 unassignedwm 00 (0/0/0) 0 5 unassignedwm 00 (0/0/0) 0 6usrwm 00 (0/0/0) 0 7 unassignedwm 00 (0/0/0) 0 created new pool and I have the following: bash-3.00# zpool list NAMESIZEUSED AVAILCAP HEALTH ALTROOT mypool 68G 53.1G 14.9G78% ONLINE - mypool299.5G 80K 99.5G 0% ONLINE - so now I will try to replace it...

Re: [zfs-discuss] zfs migration
yeah it does something funky that I did not expect, zpool seems like its taking slice 0 of that emc lun rather than taking the whole device... so when I did create that lun, I formated disk and it looked like this: format verify Primary label contents: Volume name = ascii name = DGC-RAID5-0324 cyl 51198 alt 2 hd 256 sec 16 pcyl= 51200 ncyl= 51198 acyl=2 nhead = 256 nsect = 16 Part TagFlag Cylinders SizeBlocks 0 rootwm 0 -63 128.00MB(64/0/0) 262144 1 swapwu 64 - 127 128.00MB(64/0/0) 262144 2 backupwu 0 - 51197 100.00GB(51198/0/0) 209707008 3 unassignedwm 00 (0/0/0) 0 4 unassignedwm 00 (0/0/0) 0 5 unassignedwm 00 (0/0/0) 0 6usrwm 128 - 51197 99.75GB(51070/0/0) 209182720 7 unassignedwm 00 (0/0/0) 0 that is the reason when I was trying to replace the other disk zpool did take slice 0 of that disk which was 128mb and treated it as pool rather than taking the whole disk or slice 2 or whatever it does with normal devices... I have that system connected to EMC clarion and I am using powerpath software from emc to do multipathing and stuff... ehh.. will try to replace that device old internal disk with this one and lets see how that will work. thanks so much for help.

Re: [zfs-discuss] zfs migration
Sorry to bother you but something is not clear to me regarding this process.. Ok, lets sat I have two internal disks (73gb each) and I am mirror them... now I want to replace those two mirrored disks into one LUN that is on SAN and it is around 100gb.

Any ideas if what I am planning to do is duable? or do I need to use zfs send and receive and just update everything and switch when I am done? or do I just add this SAN disk to the existing pool and then remove mirror somehow?

You can attach any number of devices to a mirror. You can detach all but one of the devices from a mirror. Obviously, when the number is one, you don't currently have a mirror. The resulting logical size will be equivalent to the smallest device. My goal is simple to move data of two mirrored disks into one single SAN device...

The ZFS terminology is attach and detach A replace is an attach followed by detach. It is a good idea to verify that the sync has completed before detaching. zpool status will show the current status. -- richard !DSPAM:122,465f396b235932151120594! ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] zfs migration
Hello folks, I have a question. Currently I have zfs pool (mirror) on two internal disks... I wanted to connect that server to SAN, then add more storage to this pool (double the space) then start using it. Then what I wanted to do is just take out the internal disks out of that pool and use SAN only. Is there any way to do that with zfs pools? Is there any way to move data from those internal disks to external disks? I mean there are ways around it, I know I can make new pool, create snap on old and then send it over then when I am done just bring zone down make incremental sync and then switch that zone to use new pool, but I wanted to do it while I have everything up.. so my goal was to add another disk (SAN) disk to my existing two disks mirrored pool, then move data while I have everything running from one internal disks to SAN and then just take those internal disks out... Any comments or suggestions greatly appreciated. Regards, Chris ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] Making 'zfs destroy' safer
Hey, that's nothing, I had one zfs file system, then I cloned it, so I thought that I had two separate file systems. then I was making snaps of both of them. Then later on I decided I did not need original file system with its snaps. So I did recursively remove it, all of a sudden I got a message that this clone file system is mounted and cannot be removed, my heart did stop for a second as that clone was a file system that I was using. I suspect that I did not promote zfs file system to be completely stand alone so ehh, I did not have idea that was the case... but it did scare me how easy I could just loose file system by removing wrong thing.

[zfs-discuss] weird thing with zfs
ok, two weeks ago I did notice one of my disk in zpool got problems. I was getting Corrupt label; wrong magic number messages, then when I looked in format it did not see that disk... (last disk) I had that setup running for few months now and all of the sudden last disk failed. So I ordered another disk, had it replaced like a week ago, I did issue replace command after disk replacement, it was resilvering disks since forever, then I got hints from this group that snaps could be causing it so yesterday I did disable snaps and this morning I di dnotice the same disk that I replaced is gone... Does it seem weird that this disk would fail? Its new disk... I have Solaris 10 U2, 4 internal drives and then 7 external drives which are in single enclousures connected via scsi chain to each other... So it seems like last disk is failing. Those nipacks from sun have self termination so there is no terminator at the end... Any ideas what should I do? Do I need to order another drive and replace that one too? Or will it happen again? What do you think could be the problem? Ah, when I look at that enclosure I do see green light on it so it seems like it did not fail... format Searching for disks... efi_alloc_and_init failed. done AVAILABLE DISK SELECTIONS: 0. c1t0d0 SEAGATE-ST337LC-D703 cyl 45265 alt 2 hd 16 sec 809 /[EMAIL PROTECTED],60/[EMAIL PROTECTED]/[EMAIL PROTECTED],0 1. c1t1d0 SEAGATE-ST337LC-D703 cyl 45265 alt 2 hd 16 sec 809 /[EMAIL PROTECTED],60/[EMAIL PROTECTED]/[EMAIL PROTECTED],0 2. c1t2d0 SEAGATE-ST337LC-D703-279.40GB /[EMAIL PROTECTED],60/[EMAIL PROTECTED]/[EMAIL PROTECTED],0 3. c1t3d0 SEAGATE-ST337LC-D703-279.40GB /[EMAIL PROTECTED],60/[EMAIL PROTECTED]/[EMAIL PROTECTED],0 4. c3t0d0 SEAGATE-ST3146807LC-0007-136.73GB /[EMAIL PROTECTED],60/[EMAIL PROTECTED]/[EMAIL PROTECTED],0 5. c3t1d0 SEAGATE-ST3146807LC-0007-136.73GB /[EMAIL PROTECTED],60/[EMAIL PROTECTED]/[EMAIL PROTECTED],0 6. c3t2d0 SEAGATE-ST3146807LC-0007-136.73GB /[EMAIL PROTECTED],60/[EMAIL PROTECTED]/[EMAIL PROTECTED],0 7. c3t3d0 SEAGATE-ST3146807LC-0007-136.73GB /[EMAIL PROTECTED],60/[EMAIL PROTECTED]/[EMAIL PROTECTED],0 8. c3t4d0 SEAGATE-ST3146807LC-0007-136.73GB /[EMAIL PROTECTED],60/[EMAIL PROTECTED]/[EMAIL PROTECTED],0 9. c3t5d0 SEAGATE-ST3146807LC-0007-136.73GB /[EMAIL PROTECTED],60/[EMAIL PROTECTED]/[EMAIL PROTECTED],0 10. c3t6d0 drive type unknown /[EMAIL PROTECTED],60/[EMAIL PROTECTED]/[EMAIL PROTECTED],0 zpool status -v pool: mypool state: ONLINE scrub: none requested config: NAMESTATE READ WRITE CKSUM mypool ONLINE 0 0 0 mirrorONLINE 0 0 0 c1t2d0 ONLINE 0 0 0 c1t3d0 ONLINE 0 0 0 errors: No known data errors pool: mypool2 state: DEGRADED scrub: resilver completed with 0 errors on Mon Dec 4 22:34:57 2006 config: NAME STATE READ WRITE CKSUM mypool2 DEGRADED 0 0 0 raidz DEGRADED 0 0 0 c3t0d0ONLINE 0 0 0 c3t1d0ONLINE 0 0 0 c3t2d0ONLINE 0 0 0 c3t3d0ONLINE 0 0 0 c3t4d0ONLINE 0 0 0 c3t5d0ONLINE 0 0 0 replacing UNAVAIL 0 775 0 insufficient replicas c3t6d0s0/o UNAVAIL 0 0 0 cannot open c3t6d0 UNAVAIL 0 940 0 cannot open errors: No known data errors ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

You may just have another bad drive and want to try replacing it again. If that does not work you, you may have another problem such as a bad backplane or a bad SCSI cable assuming the drive is an external drive. Hope that helps.

Re: [zfs-discuss] Re: [osol-discuss] Cloning a disk w/ ZFS in it
yeah disks need to be identical but why do you need to do prtvtoc and fmthard to duplicate the disk label (before the dd), I thought that dd would take care of all of that... whenever I used dd I used it on slice 2 and I never had to do prtvtoc and fmthard...

What is the fastest way to clone it to the second disk. I have to build 10 of those in 2 days. Once I build the disks I slam them to the other X2100s and ship it out. if clone really means make completely identical then do this: boot of cd or network. dd if=/dev/dsk/sourcedisk of=/dev/dsk/destdisk Where sourcedisk and destdisk are both localally attached. I use prtvtoc and fmthard to duplicate the disk label (before the dd) Note: the actual disk geometry may change between vendors or disk firmware revs. You will first need to verify that the geometries are similar, especially the total number of blocks. For dd, I'd use a larger block size than the default. Something like: dd bs=1024k if=/dev/dsk/sourcedisk of=/dev/dsk/destdisk The copy should go at media speed, approximately 50-70 MBytes/s for the X2100 disks. -- richard ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss !DSPAM:122,45390d6810494021468! ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

[zfs-discuss] mounting during boot
Hello everyone, I just wanted to play with zfs just a bit before I start using it at my workplace on servers so I did set it up on my Solaris 10 U2 box. I used to have all my disks mounted as UFS and everything was fine. I had my /etc/vfstab as such: # fd - /dev/fd fd - no - /proc - /proc proc - no - /dev/dsk/c1t0d0s1 - - swap - no - /dev/dsk/c1t0d0s0 /dev/rdsk/c1t0d0s0 / ufs1 no logging /dev/dsk/c1t0d0s6 /dev/rdsk/c1t0d0s6 /usr ufs1 no logging /dev/dsk/c1t0d0s5 /dev/rdsk/c1t0d0s5 /var ufs1 no logging /dev/dsk/c1t0d0s7 /dev/rdsk/c1t0d0s7 /d/d1 ufs2 yes logging /devices - /devices devfs - no - ctfs - /system/contractctfs- no - objfs - /system/object objfs - no - swap - /tmptmpfs - yes - /dev/dsk/c1t1d0s7 /dev/rdsk/c1t1d0s7 /d/d2 ufs 2 yes logging /d/d2/downloads - /d/d2/web/htdocs/downloads lofs2 yes - /d/d1/home/cw/pics - /d/d2/web/htdocs/pics lofs2 yes - So I decided to put /d/d2 drive on zfs, created my pool, then did create zfs an dmounted it under /d/d2 while I did copy content od /d/d2 to my new zfs and then removed it from vfstab file. Ok, so now line where is does say: /dev/dsk/c1t1d0s7 /dev/rdsk/c1t1d0s7 /d/d2 ufs 2 yes logging is commented out from my vfstab file. I rebooted my system just to get all my things started as I wanted (well I did bring all webservers and everything else down for the duration of copy so that nothing was accessing /d/d2 drive). So my system is booting up and I cannot login. aparently my service: svc:/system/filesystem/local:default went into maitenance mode... somehow system could not mount those two items from vfstab: /d/d2/downloads - /d/d2/web/htdocs/downloads lofs2 yes - /d/d1/home/cw/pics - /d/d2/web/htdocs/pics lofs2 yes - I could not login and do anything, had to login trough console put my service svc:/system/filesystem/local:default out of maitenance mode, clear maitenance state and all my services started to get going and system was no longer in single user mode... That sucks a bit since how can I mount both UFS drives, then mount zfs and then get lofs mountpoints after? Also if certain dysks did not mount I used to go to /etc/vfstab and was able to see what was going on, now since zfs does not use vfstab how can I know what was mounted or not before system went down? Sometimes drives go bad, sometimes certain dysks are commented out in vfstab such as backup disks, with zfs it is controlled trough command line, what if I do not want to boot something at boot time? How can I distinguish what suppose to be mounted at boot and whats not uzing zfs list? is there a config file that I can just comment out few lines and be able to mount them at other times other than boot? Thanks for suggestions... and sorry if this is wrong group to post such question since this is not a question about opensolaris but zfs on Solaris 10 Update 2.

Re: [zfs-discuss] Properties of ZFS snapshots I'd like to see...
Maybe there could be a flag for certain snaps where it could be made read only?!? But I dont know how this could be implemented and I do not think that would be possible... Anyway I still think that if I had a production system with those snaps I would rather remove that golden image and continue with operations rather than have no space and put my system to a halt. :) On Fri, 5 May 2006, Darren J Moffat wrote: Krzys wrote: I did not think of it this way and it is a very valid point, but I still think that most likely you would have a backup already on tape if need be and haveing space available for writing rhather than having no disk space for live data is much more important than a snap, but thats my opinion.

Re: [zfs-discuss] Properties of ZFS snapshots I'd like to see...
I realy do like the way NetApp is handling snaps :) that would be an excelent thing in ZFS :) On Fri, 5 May 2006, Marion Hakanson wrote: Interesting discussion. I've often been impressed at how NetApp-like the overal ZFS feature-set is (implies that I like NetApp's). Is it verboten to compare ZFS to NetApp? I hope not NetApp has two ways of making snapshots. There is a set of automatic snapshots, which are created, rotate and expire on their own (i.e. the filer does all of this). Often you'll have a number of hourly, daily, weekly, etc. snapshots in this category. These are the ones that users can count on seeing when they seek to perform a self-recovery of a mistakenly damaged file. Then you have the ones you create manually, or which are created by backup software. The filer itself will never delete these, it's up to the external creator to manage them. This has proven to be a fantastic model for the usage patterns that I have experienced (over probably 6+ years of NetApp use), and I would like to see something similar available for ZFS. Personally, I think that having an expiration time (and creation) be associated with the snapshot/pool itself is a good thing. What happens if one exports said filesystem/pool (with snapshots) to another system, if such creation/expiration is handled by some outside utility? Hmm, I'm not sure if the NetApp auto-snapshot schedule follows a disk volume if it's exported to a different filer. I think it doesn't.
