At the time of oops, an lvm snapshot of the XFS home directory is mounted for use by the backup scripts: mkdir -p /tmp/$from; /sbin/lvcreate -s -L 20G -n snap-shot $from && mount -o nouuid,ro /dev/$vgroup/snap-shot /tmp/$from (previously this called xfs_freeze -f / -u too but now lvcreate -s does this itself) When the rsync has finished the following commands are run: umount /tmp/$from ; /sbin/lvremove -f /dev/$vgroup/snap-shot ; rmdir /tmp/$from The umount failed and now we have a stuck mount of the snapshot. I know a reboot will fix the issue but it's both an annoying and infrequent problem. Cheers, Stu. --------------000605070204050902000506 Content-Type: text/plain; name="gpf.txt" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="gpf.txt" [5634735.319443] general protection fault: 0000 [1] SMP [5634735.319483] CPU 5 [5634735.319508] Modules linked in: tcp_diag inet_diag xt_multiport iptable_filter ip_tables x_tables cpufreq_stats cpufreq_ondemand cpufreq_powersave cpufreq_conservative cpufreq_userspace freq_table microc [5634735.319879] Pid: 6394, comm: umount Not tainted 2.6.26-2-amd64 #1 [5634735.319913] RIP: 0010:[] [] is_bad_inode+0x2/0x11 [5634735.319972] RSP: 0018:ffff810100465d40 EFLAGS: 00010246 [5634735.320004] RAX: 0000000000000000 RBX: ffff81022e69ad80 RCX: ffff810080a92000 [5634735.320056] RDX: ffff81000106e140 RSI: 0000000000000001 RDI: 65726f6e67692067 [5634735.320107] RBP: ffff810210f8c480 R08: 0000000000000296 R09: ffff810001102180 [5634735.320159] R10: ffff810210f8c6c0 R11: ffffffffa024c1a2 R12: 0000000000076029 [5634735.320210] R13: 65726f6e67692067 R14: ffff8100a5b134a0 R15: 0000000000000001 [5634735.320263] FS: 00007f0209d7d730(0000) GS:ffff81023f12b6c0(0000) knlGS:0000000000000000 [5634735.320317] CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b [5634735.320349] CR2: 00007f7841144000 CR3: 00000002385c7000 CR4: 00000000000006e0 [5634735.320401] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [5634735.320452] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [5634735.320505] Process umount (pid: 6394, threadinfo ffff810100464000, task ffff8100b6b714f0) [5634735.320558] Stack: ffffffffa024337d ffff8101728dd000 ffffffffa023f902 0000000100000296 [5634735.320620] ffff81018519b100 ffff810210f8c6c0 ffff81022e69ad80 ffff810210f8c480 [5634735.320678] 0000000000076029 ffff810100465df8 ffffffffa024be60 ffff810210f8c480 [5634735.320718] Call Trace: [5634735.320789] [] ?
