[zfs-discuss] Recover data from detached ZFS mirror
I've detached disk from a mirrored zpool using zpool detach (not zpool split) command. Is it possible to recover data from that disk? If yes, how? (and how to make it bootable) -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] panic[cpu0]/thread=ffffff0016e03c40: zfs: allocating allocated segment...
Hello Victor, thanks a lot for your help. I'm just going to buy some new drives here to be able to backup this pool, but anyway, what do you suggest to do with such pool later? Complete destroy and reinstall? Or is it possible to run scrub on read-only pool to recover it? I see this bugreport: http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6616286 which is already closed so I'm wondering if this bug is still present but not loaded into your bug db? i.e. any silent corruption bug in ZFS makes me a little bit nervous... Thanks! Karel With Solaris 11 Express you can import your pool in readonly fashion like this: zpool import -o readonly=on poolname that way you should be able to backup all your important data.

[zfs-discuss] How to zfs send current stage of fs from read-only pool?
Hello, I'm trying to recover from zfs pool crash described here: http://www.opensolaris.org/jive/thread.jspa?threadID=135675tstart=0 -- I've successfully used Victor's advice and now I do have my pool imported in read-only mode. I see the data on filesystems and would like to backup all of them using zfs send/zfs receive to another backup pool. My problem is that `zfs send' supports sending only of snapshot and I cannot create any new snapshot on the read-only pool. Is there any workaround for this? Something for example like virtual @now snapshot would be great to have for those purposes IMHO... Thanks for any idea!

[zfs-discuss] OCZ RevoDrive ZFS support
Hello, I'm curious if there is a support for OCZ RevoDrive SSD or any other SSD hooked directly on PCIe in Solaris. This RevoDrive looks particularly interesting for its low price and why to buy something SATA based when someone might have twice the speed on PCIe for the same money Thanks, Karel -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] Strange behavior of b151a and .zfs directory
Hello, after upgrade to Sol11Express I've noticed kind of strange behavior of .zfs directory of any ZFS filesystem. Go into the .zfs directory and type `find . -type f' for the first time after you've mounted the file-system. It'll show nothing. Type it second time and you will get expected list of files from all the snapshots. Is this expected or is it a bug? I don't remember seeing this on OS2009.06.

Re: [zfs-discuss] OCZ RevoDrive ZFS support
I'm curious if there is a support for OCZ RevoDrive SSD or any other SSD hooked directly on PCIe in Solaris. The RevoDrive should not require a custom device driver as it is based on the Silicon Image 3124 PCI-X RAID controller connected to a Pericom PCI-X to PCIe bridge chip (PI7C9X130). The required driver would be the si3124(7D), I noticed the man page states NCQ is not supported. I found the following link detailing the status: http://opensolaris.org/jive/thread.jspa?messageID=466436 It might make an interesting L2ARC device, as it is definitely low cost. It's based on multiple SandForce 1200 controllers. Important to note because the on-board volatile caches are not power protected, so not a good fit for the ZIL Accelerator. But perfectly acceptable for the L2ARC as drive contents are not required to survive a power failure (at this time). Our PCIe based SSD, the DDRdrive X1, does require a dedicated device driver and we exclusively target ZIL acceleration. We support OpenSolaris (2009-06 through b134), OpenIndiana, and NexentaStor 3.0. I am excited to announce we just completed validation and are now also supporting Solaris 11 Express!
