So, I think the issue I've been having *may* be related. I store a bunch of junk on an LVM and I needed to expand that a bit. So I created a "virtual disk" using dd and losetup to expand my LVM.
Everything seems fine, but after some case that I'm having a hard time identifying, I cease to be able to view certain parts of the file system on my LVM and my dmesg and /var/log/messages get flooded with stuff like [code] CIFS VFS: Unexpected lookup error -112 [/code] and [code] Mar 21 07:59:52 Dauntless kernel: [35010.428444] rm D ffffffff80234069 0 8160 21157 Mar 21 07:59:52 Dauntless kernel: [35010.428449] ffff88009783fe28 0000000000000086 ffff88008aa606c8 ffffffff806e2700 Mar 21 07:59:52 Dauntless kernel: [35010.428455] ffffffff807a6400 ffffffff807a6400 ffffffff807a6400 ffffffff807a6400 Mar 21 07:59:52 Dauntless kernel: [35010.428460] ffffffff807a6400 ffffffff807a6400 ffffffff807a6400 ffffffff807a6400 Mar 21 07:59:52 Dauntless kernel: [35010.428465] Call Trace: Mar 21 07:59:52 Dauntless kernel: [35010.428469] [<ffffffff802f5f1f>] ? path_walk+0xcf/0xe0 Mar 21 07:59:52 Dauntless kernel: [35010.428473] [<ffffffff80502435>] __mutex_lock_slowpath+0x85/0xd0 Mar 21 07:59:52 Dauntless kernel: [35010.428478] [<ffffffff805021d3>] mutex_lock+0x23/0x30 Mar 21 07:59:52 Dauntless kernel: [35010.428481] [<ffffffff802f667f>] do_unlinkat+0x8f/0x1d0 Mar 21 07:59:52 Dauntless kernel: [35010.428485] [<ffffffff802f8c13>] ? do_vfs_ioctl+0x273/0x2f0 Mar 21 07:59:52 Dauntless kernel: [35010.428489] [<ffffffff802f6922>] sys_unlinkat+0x22/0x40 Mar 21 07:59:52 Dauntless kernel: [35010.428493] [<ffffffff8021285a>] system_call_fastpath+0x16/0x1b [/code] Also..

But I think it may well be.
