Hello, I've run into a problem with zpool import that seems very similar to the following thread as far as I can tell:
http://opensolaris.org/jive/thread.jspa?threadID=70205&tstart=15 The suggested solution was to use a later version of open solaris (b99 or later) but that did not work. I've tried the following versions of solaris without success: Solaris 10 u4 (original system) Solaris 10 u6 Opensolaris 2008.11 Opensolaris 2008.11 b99 SXCE b113 Any help with this will be greatly appreciated...my last backup was four months ago so a lot of my thesis work will be lost. I mistakenly thought a mirrored zpool on new drives would be good enough for a while. So here's what happened: we had a power outage one day and as soon as I tried to boot the server again it enters an endless reboot cycle. So I thought the OS drive became corrupted (not mirrored) and reinstalled the OS. Then when I try zpool import it hangs forever. I even left it going for a couple days in case it was trying to correct corrupted data. The same thing happens no matter what version of solaris I use. The symptoms and diagnostic results (see below) seem to be very similar to the post above but the solution doesn't work. Please let me know if you need any other information. Thanks, Brad bash-3.2# zpool import pool: tank id: 4410438565134310480 state: ONLINE status: The pool is formatted using an older on-disk version. action: The pool can be imported using its name or numeric identifier, though some features will not be available without an explicit 'zpool upgrade'. config: tank ONLINE mirror ONLINE c2d0p0 ONLINE c1d0p0 ONLINE bash-3.2# zpool import tank cannot import 'tank': pool may be in use from other system use '-f' to import anyway bash-3.2# zpool import -f tank (then it hangs here forever, can't be killed) (the following commands were performed while this was running) bash-3.2# fmdump -eV TIME CLASS May 27 2009 22:22:55.308533986 ereport.fs.zfs.checksum nvlist version: 0 class = ereport.fs.zfs.checksum ena = 0xd22e37db9000401 detector = (embedded nvlist) nvlist version: 0 version = 0x0 scheme = zfs pool = 0x3d350681ea839c50 vdev = 0x85cc302105002c5d (end detector) pool = tank pool_guid = 0x3d350681ea839c50 pool_context = 0 pool_failmode = wait vdev_guid = 0x85cc302105002c5d vdev_type = disk vdev_path = /dev/dsk/c2d0p0 vdev_devid = id1,c...@ast3750640as=____________5qd3myrh/q parent_guid = 0x8fb729a008f16e65 parent_type = mirror zio_err = 50 zio_offset = 0x2500407000 zio_size = 0x1000 zio_objset = 0x0 zio_object = 0x23 zio_level = 0 zio_blkid = 0x0 __ttl = 0x1 __tod = 0x4a1e038f 0x1263dae2 (and many others just like this) bash-3.2# echo "0t3735::pid2proc|::walk thread|::findtsack -v" | mdb -k stack pointer for thread df6ed220: e1ca8c54 e1ca8c94 swtch+0x188() e1ca8ca4 cv_wait+0x53(e08442aa, e084426c, ffffffff, f9c305ac) e1ca8ce4 txg_wait_synced+0x90(e0844100, 252b4c, 0, 0) e1ca8d34 spa_config_update_common+0x88(d6c429c0, 0, 0, e1ca8d68) e1ca8d84 spa_import_common+0x3cf() e1ca8db4 spa_import+0x18(dbfcf000, e3c0d018, 0, f9c65810) e1ca8de4 zfs_ioc_pool_import+0xcd(dbfcf000, 0, 0) e1ca8e14 zfsdev_ioctl+0x124() e1ca8e44 cdev_ioctl+0x31(2d80000, 5a02, 80418d0, 100003, dfde91f8, e1ca8f00) e1ca8e74 spec_ioctl+0x6b(d7a593c0, 5a02, 80418d0, 100003, dfde91f8, e1ca8f00) e1ca8ec4 fop_ioctl+0x49(d7a593c0, 5a02, 80418d0, 100003, dfde91f8, e1ca8f00) e1ca8f84 ioctl+0x171() e1ca8fac sys_sysenter+0x106() bash-3.2# echo "::threadlist -v" | mdb -k d4ed8dc0 fec1f558 0 0 60 d5033604 PC: _resume_from_idle+0xb1 THREAD: txg_sync_thread() stack pointer for thread d4ed8dc0: d4ed8ba8 swtch+0x188() cv_wait+0x53() zio_wait+0x55() vdev_uberblock_sync_list+0x19e() vdev_config_sync+0x11c() spa_sync+0x5a5() txg_sync_thread+0x308() thread_start+8() (just chose one seemingly relevant thread from the long list) bash-3.2# zdb -e -bb tank Traversing all blocks to verify nothing leaked ...
