Re: [zfs-discuss] Kernel panic on zpool import. 200G of data inaccessible!
I can not help but agree with Tim's comment below. If you want a free version of ZFS, in which case you are still responsible for things yourself - like having backups, then maybe: www.freenas.org www.linuxonzfs.org www.openindiana.org Meanwhile, it is grossly inappropriate to be complaining about lack of support when using an operating system / file system that you know has no support. Doubly so if your data is important and doubly so again if did not already back it up. - mike On Aug 19, 2011, at 6:54 AM, Tim Cook wrote: > > > You digitally signed a license agreement stating the following: > No Technical Support > Our technical support organization will not provide technical support, phone > support, or updates to you for the Programs licensed under this agreement. > > To turn around and keep repeating that they're "holding your data hostage" is > disingenuous at best.

I believe you can configure VirtualBox for Windows to pass thru the disk with your unimportable rpool to guest OSs. Can OpenIndiana or FreeBSD guest import the pool?

Given I can boot to single user mode and elect not to import or mount any pools, and that later I can issue an import against only the pool I need, I don't understand how this can help.

Re: [zfs-discuss] Kernel panic on zpool import. 200G of data inaccessible!
Hi Paul, > 1. Install system to pair of mirrored disks (c0t2d0s0 c0t3d0s0), > system works fine I don't remember at this point which disks were which, but I believe it was 0 and 1 because during the first install there were only 2 drives in the box because I had only 2 drives. > 2. add two more disks (c0t0d0s0 c0t1d0s0), create zpool tank, test and > determine these disks are fine Again, probably was on disks 2 and 3 but in principle, correct. > 3. copy data to save to rpool (c0t2d0s0 c0t3d0s0) I did this in a few steps that probably don't make sense because I had only 2 500G drives at the beginning when I did my install. Later I got two 320G and realized I should have the root pool on the smaller drives. But in the interim, I installed the new pair of 320G and moved a bunch of data onto that pool. After the initial installation when update 8 first came out, what happened next was something like: 1. I created tank mirror on the 2 320G drives and moved data from another system on to the tank. After I verified it was good I rebooted the box and checked again and everything was healthy, all pools were imported and mounted correctly. 2. Then I realized I should install on the 320s and use the 500s for storage so I copied everything I had just put on the 320s (tank) onto the 500s (root). I rebooted again and verified the data on root was good, then I deleted it from tank. 3. I installed a new install on the 320s (formerly tank) 4. I rebooted and it used my old root on the 500s as root, which surprised me but makes sense now because it was created as rpool during the very first install. 5. I rebooted in single user mode and tried to import the new install. It imported fine. 6. I don't know what happened next but I believe after that I rebooted again to see why Solaris didn't choose the new install, the tank pool could not be imported and I got the panic shown in the screenshot. > 3. install OS to c0t0d0s0, c0t1d0s0 > 4. reboot, system still boots from old rpool (c0t2d0s0 c0t3d0s0) Correct. At some point I read you can change the name of the pool so I imported rpool as tank and that much worked. At this point both pools were still good, and now the install was correctly called rpool and my tank was called tank. > 5. change boot device and boot from new OS (c0t0d0s0 c0t1d0s0) That was the surprising thing. I had already changed my BIOS to boot from the new pool, but that didn't stop Solaris from using the old install as the root pool, I guess because of the name. I thought originally as long as I specified the correct boot device I wouldn't have any problem, but even taking the old rpool out of the boot sequence and specifying only the newly installed pool as boot devices wasn't enough. > 6. cannot import old rpool (c0t2d0s0 c0t3d0s0) with your data > > At this point could you still boot from the old rpool (c0t2d0s0 c0t3d0s0) ? Yes, I could use the newly installed pool to boot from, or import it from shell in several versions of Solaris/Sol 11, etc. Of course now I cannot, since I have installed so many times over that pool trying to get the other pool imported. > > and > > 7. cannot import old rpool (c0t2d0s0 c0t3d0s0), any attempt causes a > kernel panic, even when booted from different OS versions Right.

Re: [zfs-discuss] Kernel panic on zpool import. 200G of data inaccessible!
I am catching up here and wanted to see if I correctly understand the
chain of events...
1. Install system to pair of mirrored disks (c0t2d0s0 c0t3d0s0),
system works fine
2. add two more disks (c0t0d0s0 c0t1d0s0), create zpool tank, test and
determine these disks are fine
3. copy data to save to rpool (c0t2d0s0 c0t3d0s0)
3. install OS to c0t0d0s0, c0t1d0s0
4. reboot, system still boots from old rpool (c0t2d0s0 c0t3d0s0)
5. change boot device and boot from new OS (c0t0d0s0 c0t1d0s0)
6. cannot import old rpool (c0t2d0s0 c0t3d0s0) with your data
At this point could you still boot from the old rpool (c0t2d0s0 c0t3d0s0) ?
and
7. cannot import old rpool (c0t2d0s0 c0t3d0s0), any attempt causes a
kernel panic, even when booted from different OS versions
Have you been using the same hardware for all of this ?

iirc if you use two hdd, you can import the zpool can you try to import -R with only two hdd at time Sent from my iPad Hung-Sheng Tsao ( LaoTsao) Ph.D On Aug 15, 2011, at 13:42, Stu Whitefish wrote: > Unfortunately this panics the same exact way.

[zfs-discuss] Kernel panic on zpool import. 200G of data inaccessible!
I am opening a new thread since I found somebody else reported a similar failure in May and I didn't see a resolution hopefully this post will be easier to find for people with similar problems. Original thread was http://opensolaris.org/jive/thread.jspa?threadID=140861 System: snv_151a 64 bit on Intel. Error: panic[cpu0] assertion failed: zvol_get_stats(os, nv) == 0, file: ../../common/fs/zfs/zfs_ioctl.c, line: 1815 Failure first seen on Solaris 10, update 8 History: I recently received two 320G drives and realized from reading this list it would have been better if I would have done the install on the small drives but I didn't have them at the time. I added the two 320G drives and created tank mirror. I moved some data from other sources to the tank and then decided to go ahead and do a new install. In preparation for that I moved all the data I wanted to save onto the rpool mirror and then installed Solaris 10 update 8 again on the 320G drives. When my system rebooted after the installation, I saw for some reason it used my tank pool as root. I realize now since it was originally a root pool and had boot blocks this didn't help. Anyway I shut down, changed the boot order and then booted into my system. It paniced when trying to access the tank and instantly rebooted. I had to go through this several times until I caught a glimpse of one of the first messages: assertion failed: zvol_get_stats(os, nv) Here is what my system looks like when I boot into failsafe mode. # zpool import pool: rpool id: 16453600103421700325 state: ONLINE action: The pool can be imported using its name or numeric identifier. config: rpool ONLINE mirror ONLINE c0t2d0s0 ONLINE c0t3d0s0 ONLINE pool: tank id: 12861119534757646169 state: ONLINE action: The pool can be imported using its name or numeric identifier. config: tank ONLINE mirror ONLINE c0t0d0s0 ONLINE c0t1d0s0 ONLINE # zpool import tank cannot import 'tank': pool may be in use from other system use '-f' to import anyway Here is a photo of my screen (hah hah old fashioned "screen shot") when Sol 11 starts now that I tried importing my pool it fails constantly. # zpool import -f tank http://imageshack.us/photo/my-images/13/zfsimportfail.jpg/ I installed Solaris 11 Express USB via Hiroshi-san's Windows tool. Unfortunately it also panics trying to import the pool although zpool import shows the pool online with no errors just like in the above doc. and here is an eerily identical photo capture made by somebody with a similar/identical error. http://prestonconnors.com/zvol_get_stats.jpg At first I thought it was a copy of my screenshot but I see his terminal is white and mine is black. Looks like the problem has been around since 2009 although my problem is with a newly created mirror pool that had plenty of space available (200G in use out of about 500G) and no snapshots were taken. Similar discussion with discouraging lack of follow up: http://opensolaris.org/jive/message.jspa?messageID=376366 Looks like the defect, it's closed and I see no resolution. https://defect.opensolaris.org/bz/show_bug.cgi?id=5682 I have about 200G of data on the tank pool, about 100G or so I don't have anywhere else. I created this pool specifically to make a "safe place" to store data that I had accumulated over several years and didn't have organized yet.
