[zfs-discuss] Re: What SATA controllers are people using for ZFS?
After failed luck with a pair of Syba SD-SATA-4P PCI-X SATA II controllers (Sil3114 chipset), I've now successfully used a Tekram TR-834A 4-port SATA-II controller (Sil3124-2 chipset) at the full PCI-X 133MHz bus speed and b50. Since my disk mirror on the previous SATA controller (built-in W1100z SATA I controller) were both ZFS, a simple zpool export zfsdata, touch /reconfigure, init 6, zpool import zfsdata was all that was need to migrate my ZFS data to this new hardware...including a few zones. VERY cool. This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] Re: NFS share problem with mac os x client
In short - make sure your UID on Mac is enough to access the files on nfs (as it would be if you would try to access those files locally). Or perhaps you tried from user with uid=0 in which case it's mapped to nobody user by default. -- Best regards, Robert Exactly as Robert suggests. I've had the same problem but it turned out to simply be that I needed the OS X group and user ID's to match those setup on the ZFS OpenSolaris server. Once you correct this, the Finder will work great to a ZFS NFS share.

[zfs-discuss] Re: ZFS on PC Based Hardware for NAS?
I believe there is a write limit (commonly 10 writes) on CF and similar storage devices, but I don't know for sure. Apart from that I think it's a good idea. James C. McPherson As a consequence, the /tmp, /var, and swap could eventually be moved to the ZFS hard drives to greatly reduce I/O to the CF card.

Perhaps the other model listed above works better, I don't know. In the end, I just stuck with my onboard SATA I/O which is only SATA 150, but was still fast enough for my network. For my ZFS home server, I was able to find an excellent Sun W1100z on eBay ~$360 that came with a 2.4GHz Opteron, 1GB ECC RAM, Quardro FX 500, and 80Gb IDE drive - perfect for the basis of my ZFS server build-up. To that I've added two Seagate Barracude ES ST3400620NS 400Gb SATA II drives for about $360 that now run my 400Gb whole-disk ZFS mirror. Overall I'm in for $720 for a great server/workstation with 400Gb of redundant storage, not bad, and performance is much better, with much greater functionality, than most $1,000+ home NAS systems I've seen. At first I thought I'd toss the IDE drive, but I ended up just put the OS on it with all my data and zones on the ZFS mirror...at least until ZFS root. One of these days I'll get around to finishing the blog about it: http://classiarius.com/W1100z%20Home%20ZFS%20Server/W1100z%20Home%20ZFS%20Server.html HTH. Wes W.

[zfs-discuss] Re: Advice Wanted - sharing across multiple non global zones
Hi.. After searching hi low, I cannot find the answer for what I want to do (or at least understand how to do it). I am hopeful somebody can point me in the right direction. I have (2) non global zones (samba www) I want to be able to have all user home dir's served from zone samba AND be visable under zone www as the users public_html dir. I have looked at delegating a dataset to samba and creating a new fs for each user but then I cannot share that with www. I also tried creating the fs under the global zone and mounting that via lofs but that did not seem to carry over each underlying fs and lost the quota capability. I cannot share via NFS since non global zones cannot mount from the same server. How can I achieve what I want to do? The requirements are: User Quotas (needs a file system for each user) Share file systems across multiple non global zones (rw) I have close to 3000 users so it must be a manageable approach and hopefully allow me to use the root preexec of samba to auto create user dir's. Have a peek at this page: http://www.sun.com/software/solaris/howtoguides/s10securityhowto.jsp I believe it may give you some insights to your final objective.

[zfs-discuss] Re: disappearing mount - expected behavior?
What happens is that /home/thomas/zfs gets mounted and then the automounter starts. (Or /home/thomas is found missing and then the zfs mount is not completed) Probably requires legacy mount point. Casper ___ I'm experiencing this same behavior (ZFS NFS mounts don't show after reboot) with b50 and was hoping someone could outline a little clearer for those of us not as intimately familiar with Solaris innards. I can simply issue one 'zfs share zfsdata/[user1]' command and all my other ZFS-issued NFS mount points reappear. My /etc/auto_home is: [user1] 127.0.0.1:/export/home/[user1] [user2] 127.0.0.1:/export/home/[user2] etc... All SMF services are running normally - nothing in maintenance or failed to run. I dot NOT have any entries in my /etc/vfstab pertaining to the /export/home directories, all of which are on a ZFS pool. Should I simply comment out the /etc/auto_home entries? Or, should I create an entry in /etc/vfstab? If so, is one to /export/home sufficient or must one be done for each user [each user has his/her own ZFS pool]? Sorry, I'm just not sure what a legacy mount point is. Many thanks in advance!

[zfs-discuss] OpenSolaris vs. Solaris 10 11/06 (S10u3) for NFS ZFS Server
I'm in the process of building a Solaris NFS server with ZFS and was wondering if any gurus here have any comments as to choosing the upcoming Solairs 10 11/06 [presumably] or OpenSolaris bXX/Solairs Express for this use. Even with my use of OpenSolaris I maintain a service contract to show my support, so bug fixes in a static supported version shouldn't be an issue in picking a version. So, the short question is are there any super-cool must-have ZFS/NFS features in OpenSolaris now that S10u3 won't have right away? Thanks!

[zfs-discuss] Re: OpenSolaris vs. Solaris 10 11/06 (S10u3) for NFS
[ Hi Wes from [EMAIL PROTECTED] ] And the smart-ask answer is: By Definition: the OpenSolaris/Solaris Express feature that is *your* must-have feature, probably won't be in Update 3! :) Exactly, that's why I used quotes as I'm sure I'd be happy with S10u3, assuming ignorance is bliss. Then again, I've never believed ignorance is bliss. ;) I simply don't know enough about the difference between the two OS versions yet to make an educated guess as to which venue to pursue presently - especially since S10u3 isn't released at the moment and I haven't followed ZFS closely since ZFSv1 was current. snip I don't think that there are any ZFS NFS related fixes that did'nt make it into U3 (others will correct me if I'm wrong here). It's a tough choice o make... The huge upside is ... that there is a choice! :) Indeed, knowing there are no known NFS fixes omitted is great news, not that I was aware of anything in NFS needing fixing. To me this is just reassuring since my goal is to build this box and nearly forget about it while it's hidden away and 'it just works.' Since I didn't hear anything like ZFSv3 vs. ZFSv2 or some such, I'll probably just go w/ S10u3 for this project. Thanks for your feedback Al.

I use the smartmontools smartd daemon to email me when disk drives are about to fail. If you are interested in configuring smartd to send email notifications prior to a disk failing, check out the following blog post: http://prefetch.net/blog/index.php/2006/01/05/using-sm artd-on-solaris-systems-to-find-disk-drive-problems/ Thanks, - Ryan -- UNIX Administrator http://prefetch.net ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discu ss Thanks for the feedback Ryan, I'll certainly consider this option. However, the ideal solution would also have the option send a notification at X-interval (daily), and at least let you know the monitoring is working and that there are no errors, and could also provide specific ZFS pool status update.

[zfs-discuss] ZFS Automatic Device Error Notification?
Okay, so now that I'm planning to build my NAS using ZFS, I now need to devise or learn of a preexisting method to receive notification of ZFS handled errors on a remote machine. For example, if a disk fails and I don't regularly login or SSH into the ZFS server, I'd like an email or some other notification immediately of the ZFS event. Are there already ways to do this? A few leads into what existing technologies or few keywords on what to look for would help. I've found the FMA references with SMF, but that doesn't seem to be the full answer to my quest here. It's been awhile since I've used the web-console to ZFS, perhaps this is now a feature there? If not, that would be a great addition! Thanks for any leads or tips!

[zfs-discuss] Re: Recommended Minimum Hardware for ZFS Fileserver?
Thanks gents for your replies. I've used to a very large config W2100z and ZFS for awhile but didn't know how low can you go for ZFS to shine, though a 64-bit CPU seems to be the minimum performance threshold. Now that Sun's store is [sort of] working again, I can see some X2100's with the custom configure and a very low starting price of only $450 sans CPU, drives, and memory. Great!! [b]If only we could get a basic X2100-ish designed, custom build priced, server from Sun that could also hold 3-5 drives internally[/b], I could see a bunch of those being used as ZFS file servers. This would also be a good price point for small office and home users since the X4100 is certainly overkill in this application, though I'd wouldn't refuse one offered to me. =) This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

[zfs-discuss] Re: recommended hardware for a zfs/nfs NAS?
I was wondering if anyone could recommend hardware forr a ZFS-based NAS for home use. setup, so I'm looking at sparc or opteron. Ideally it would: a) run quiet (blade 100/150 is ok, x4100 ain't :) ) Not much space in a Blade 100/150 for multiple disks, but it is quiet and cheap. For NAS use, I'd think RAID would be ideal...RAID in a Blade 100/150 isn't ideal. b) take advantage of cheap disks ( ide/sata, unless scsi suddenly got affordable) come in around the 300-400 pounds mark Ummm... Don't need massive storage, it just needs to be reliable and reasonably Reliable = redundant Redundant = multiple disks fast - I was thinking of maybe a 2-way 100Gb mirror set. Fast = $ (typically) Speed costs money. How fast do you want to go? 8) Graphics are a complete non-issue. It only needs to saturate 100mbit (I'm not planning Saturating 100Mbit with a 64-bit CPU and redundant disks for $300-400 Pounds may be tough. to use it for anything else, so CPU isn't important). True, but ZFS compression=on works very well, and potentially on-disk encryption support [down the road] with compression may change your mind. Any used sun systems fit the bill, or should I be thinking of rolling my own opteron? Thanks! Roll your own with Opteron, new disks, etc.? ...not feasible in that price range, IMHO. Depending on what your current workstation is, I just might suggest adding disks there and beef it up. Nice NAS: A nice new Ultra 20 is inexpensive, quiet, and makes a good workstation. I'd suggest beefing up your existing workstation or replacing it with a U20 with two fast SATA disks ZFS mirrors or stripes. Cheap NAS: The last option I suggest is a Blade 100/150 with only one IDE drive - you could zip tie another in the box carefully I suppose - but this isn't the most reliable place to save your personal data.

[zfs-discuss] Re: Re: recommended hardware for a zfs/nfs NAS?
Saturating 100Mbit with a 64-bit CPU and redundant disks for $300-400 Pounds may be tough. Anything in the market can saturate 100Mbit easily; even with a single cheap IDE disk. The disks are generally a factor 5-10 faster than the 100Mbit network.
