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 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. http://imageshack.us/photo/my-images/13/zfsimportfail.jpg/ 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. I can't believe such a serious bug has been around for two years and hasn't been fixed. Can somebody please help me get this data back? Thank you. Jim I joined the forums but I didn't see my post on zfs-discuss mailing list which seems alot more active than the forum. Sorry if this is a duplicate for people on the mailing list. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
