[zfs-discuss] Retrieve per-block checksum algorithm
Greetings to everyone. I'm trying to retrieve the checksumming algorithm on a per-block basis with zdb(1M). I know it's supposed to be ran by Sun's support engineers only I take full responsibility for whatever damage I cause to my machine by using it. Now. I created a tank/test filesystem, dd'ed some files, then changed the checksum to sha256 and dd'ed some more files. I retrieved the DVAs of all the files and wanted to verify that some of them are using the default and the rest the sha256 checksums. The problem is that zdb -R either returns (null), meaning that printf() has been given a NULL pointer or it returns corrupt data and there are cases where it works ok. This is a case where it fails: $ zdb -R tank:0:f076d8600:7a00:b Found vdev type: mirror DVA[0]: vdev_id 1199448952 / 4315c6bdf768bc00 DVA[0]: GANG: TRUE GRID: 00bd ASIZE: eb45ac00 DVA[0]: :1199448952:4315c6bdf768bc00:a75a00:egd DVA[1]: vdev_id 1938508981 / e19c60208f39cc00 DVA[1]: GANG: TRUE GRID: 005d ASIZE: 11fe4ac00 DVA[1]: :1938508981:e19c60208f39cc00:a75a00:egd DVA[2]: vdev_id 1231513852 / 646586e9b6609400 DVA[2]: GANG: FALSE GRID: 00e6 ASIZE: 15e953200 DVA[2]: :1231513852:646586e9b6609400:a75a00:edd LSIZE: 6efc00 PSIZE: a75a00 ENDIAN:BIG TYPE: (null) BIRTH: 2a9513965f18afdLEVEL: 24FILL: 85adfa322e48a796 CKFUNC: (null) COMP: (null) CKSUM: 7408c0516468b934:a0f29a7c28b6c319:28280aab19d1ad3c:64607350c7ea256c $ Is it a zdb deficiency of my input is to blame?

Re: [zfs-discuss] Dumb idea?
Or in OS X with smart folders where you define a set of search terms and as write operations occur on the known filesystems the folder contents will be updated to reflect the current state of the attached filesystems The structures you defined seemed to be designed around the idea of reductionism (ie - subfolders representing a subset of the parent) which cannot currently be implemented in Libraries or Smart folders since the contents are read-only listings.

How do I inform ZFS of the new path?
...
Do I need to boot from the LiveCD and then import the

Exactly.
Boot from the livecd with the disk connected on the
new physical path, and run pfexec zpool import -f rpool,
followed by a reboot.
That'll update the zpool's label with the new physical
device path information.

Re: [zfs-discuss] STK 2540 and Ignore Cache Sync (ICS)
Hi Bob; In all 2500 and 6000 series you can assign raid set's to a controller and that controller becomes the owner of the set. Generaly not force drives switching between controllers always one controller owns a disk, and other waits in standby. Some disks use ALUA and re-route traffic coming to the not preferred controller to preferred controller. While some companies market this a true active active set up, this reduces the performance significantly if the host is not %100 ALUA aware. While this architacture solves the problem of setting up MPXIO on hosts. It's likely that sometime in future Sun may release a FW to enable ALUA on controllers but this definetly wont improve performance. The advantage of 2540 against it's bigger brothers (6140 which is EOL'ed) and competitors 2540 do use dedicated data paths for cache mirroring just like higher end unit disks (6180,6580, 6780) improving write performance significantly. Spliting load between controllers can most of the time increase performance, but you do not need to split in two equal partitions. Also do not forget that first tray have dedicated data lines to the controller so generaly it's wise not to mix those drives with other drives on other trays.

I believe that in the STK 2540, the controllers operate Active/Active except that each controller is Active for half the drives and Standby for the others. Each controller has a copy of the configuration information. Whichever one you communicate with is likely required to mirror the changes to the other.

It is true that rsync (as of 3.0.5, anyway) does not preserve NFSv4/ ZFS ACL's. It also cannot handle ZFS snapshots. On the other hand, you can run multiple rsync's in parallel; You can only do that with zfs send/recv if you have multiple, independent ZFS datasets that can be done in parallel. So which one goes faster will depend on your situation. Yes. Your configuration and intended use impacts the decision.

Re: [zfs-discuss] fishworks on x4275?
Hı Trevor; As can be seen from my email adress and signiture below my answer will be quite biased J To be honest, while converting every X series server with millions of alternative configurations to a Fishwork appliance may not be extremely difficult, it would be impossible to support them. So Sun have to limit the number of configurations that needs to supported to a reasonable number. (Even this limited number of Systems and options will equal to unseen flexibility and number of choices ) However I agree that ability to convert a 4540 to a 7210 would have been nice.

The advantage of 2540 against it's bigger brothers (6140 which is EOL'ed) and competitors 2540 do use dedicated data paths for cache mirroring just like higher end unit disks (6180,6580, 6780) improving write performance significantly. Spliting load between controllers can most of the time increase performance, but you do not need to split in two equal partitions. Also do not forget that first tray have dedicated data lines to the controller so generaly it's wise not to mix those drives with other drives on other trays. But, if you have an expansion chassis, and create a zpool with drives on the first tray and subsequent trays, what's the difference? You cannot tell zfs which vdev to assign writes to so it seems pointless to balance your pool based on the chassis when reads/writes are potentially spread across all vdevs. Best regards Mertol Mertol Ozyoney Storage Practice - Sales Manager Sun Microsystems, TR Istanbul TR Phone +902123352200 Mobile +905339310752 Fax +90212335 Email mertol.ozyo...@sun.com -Original Message- From: zfs-discuss-boun...@opensolaris.org [mailto:zfs-discuss-boun...@opensolaris.org] On Behalf Of Bob Friesenhahn Sent: Tuesday, October 13, 2009 10:59 PM To: Nils Goroll Cc: zfs-discuss@opensolaris.org Subject: Re: [zfs-discuss] STK 2540 and Ignore Cache Sync (ICS) On Tue, 13 Oct 2009, Nils Goroll wrote: Regarding my bonus question: I haven't found yet a definite answer if there is a way to read the currently active controller setting.

Being a script hacker like you the only kludge I can think of.
A script that does something like
ls /tmp/foo
sleep
ls /tmp/foo.new
diff /tmp/foo /tmp/foo.new
/tmp/files_that_have_changed

Or you might be able to knock something up with bart nd zfs snapshots. I did write this which may

Question: Is there a facility similar to inotify that I can use to monitor a
directory structure in OpenSolaris/ZFS, such that it will block until a file
is modified (added, deleted, etc), and then pass the state along (STDOUT is
fine)? One other requirement: inotify can handle subdirectories being added
on the fly. So if you use it to monitor, for example, /data/images/incoming,
and a /data/images/incoming/100canon directory gets created, then the files
under that directory will automatically be monitored as well.
while there is no inotify for Solaris, there are similar technologies available.
Check port_create(3C) and gam_server(1)
I can't find much on gam_server on Solaris (couldn't find too much on it at
all, really), and port_create is apparently a system call. (I'm not a
developer--if I can't write it in BASH, Perl, or Ruby, I can't write it.)
I appreciate the suggestions, but I need something a little more pret-a-porte.
Does anyone have any dtrace experience? I figure this could probably be done
with dtrace, but I don't know enough about it to write a dtrace script
(although I may learn if that turns out to be the best way to go). I was
hoping that there'd be a script out there already, but I haven't turned up
anything yet.

The docs are... ummm... skimpy is being rather polite. The docs I can find via
Google say that they will launch some random unspecified daemons via d-bus (I
assume gvfsd ans gvfsd-${accessmethod}). This implies that you need to start a
d-bus session to use them. gvfsd (no man page or docs of any kind that I can
find) is linked against libgio, which has unresolved symbols against
port_create() and friends, which is a good sign that they don't just poll.

Re: [zfs-discuss] zfs code and fishworks fork
With that said I'm concerned that there appears to be a fork between the opensource version of ZFS and ZFS that is part of the Sun/Oracle FishWorks 7nnn series appliances. I understand (implicitly) that Sun (/Oracle) as a commercial concern, is free to choose their own priorities in terms of how they use their own IP (Intellectual Property) - in this case, the source for the ZFS filesystem. Hey Al, I'm unaware of specific plans for management either at Sun or at Oracle, but from an engineering perspective suffice it to say that it is simpler and therefore more cost effective to develop for a single, unified code base, to amortize the cost of testing those modifications, and to leverage the enthusiastic ZFS community to assist with the development and testing of ZFS. Again, this isn't official policy, just the simple facts on the ground from engineering. I'm not sure what would lead you to believe that there is fork between the open source / OpenSolaris ZFS and what we have in Fishworks. Indeed, we've made efforts to make sure there is a single ZFS for the reason stated above. Any differences that exist are quickly migrated to ON as you can see from the consistent work of Eric Schrock.

Re: [zfs-discuss] ZFS near-synchronous replication...

Near-synchronous, meaning RPO X---0 Many Solaris solutions are using AVS for this. But you could use block-level replication from a number of vendors. http://hub.opensolaris.org/bin/view/Project+avs/ I realize performance will take a hit. In general, yes. But it will depend quite a bit on the workload. For normal file system workloads with writes deferred up to 30 seconds, you may not notice the replication hit. For sync workloads, it is more likely to be noticeable. -- richard ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] zfs inotify?
I haven't tried this, but this must be very easy with dtrace. How come no one mentioned it yet? :) You would have to monitor some specific syscalls... -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

How come no one mentioned it yet? :) You would have to monitor some specific syscalls... DTrace is not reliable in this sense: it will drop events rather than overburden the system. Also, system calls are not the only thing you want to watch for -- you should really trace the VFS/fop rather than syscalls for this. In any case, port_create(3C) and gamin are the way forward. port_create(3C) is rather easy to use. Searching the web for PORT_SOURCE_FILE you'll find useful docs like: http://blogs.sun.com/praks/entry/file_events_notification which has example code too. I do think it'd be useful to have command-line utility in core Solaris that uses this facility, something like the example in Prakash's blog (which, incidentally, _works_), but perhaps a bit more complete.
