But, as I said in my initial report, the device (PV and the LV in it) contains only a ext3 FS with very few files. However, two of theses files were disk images for two running kvm (virtual) machines. Here are the relevent logs I have in /var/log/syslog (dm-1 was the LV on the PV I tried to move): May 22 00:33:26 aya kernel: [84740.882402] device-mapper: table: 253:1: linear: dm-linear: Device lookup failed May 22 00:33:26 aya kernel: [84740.882453] device-mapper: ioctl: error adding target to table [...] May 22 00:40:29 aya kernel: [85164.276120] attempt to access beyond end of device May 22 00:40:29 aya kernel: [85164.276125] dm-1: rw=0, want=13108585144, limit=19529728 [...] May 22 00:47:18 aya kernel: [85572.764165] EXT3-fs error (device dm-1): htree_dirblock_to_tree: bad entry in directory #2: directory entry across blocks - offset=0, inode=4294967295, rec_len=65536, name_len=255 May 22 00:47:34 aya kernel: [85589.092525] EXT3-fs error (device dm-1): htree_dirblock_to_tree: bad entry in directory #2: directory entry across blocks - offset=0, inode=4294967295, rec_len=65536, name_len=255 May 22 00:47:46 aya kernel: [85600.986601] EXT3-fs error (device dm-1): htree_dirblock_to_tree: bad entry in directory #2: directory entry across blocks - offset=0, inode=4294967295, rec_len=65536, name_len=255 May 22 00:48:57 aya kernel: [85672.183028] attempt to access beyond end of device May 22 00:48:57 aya kernel: [85672.183033] dm-1: rw=0, want=5462874352, limit=19529728 May 22 00:48:57 aya kernel: [85672.183037] attempt to access beyond end of device May 22 00:48:57 aya kernel: [85672.183040] dm-1: rw=0, want=5462874352, limit=19529728 May 22 00:49:09 aya kernel: [85683.975770] attempt to access beyond end of device May 22 00:49:09 aya kernel: [85672.183040] dm-1: rw=0, want=5462874352, limit=19529728 [and then, more and more identical lines (about 30 per seconde) until I reboot] May 22 00:51:02 aya kernel: [85796.603342] attempt to access beyond end of device May 22 00:51:02 aya kernel: [85796.603347] dm-1: rw=0, want=24441388824, limit=19529728 May 22 00:52:47 aya kernel: imklog 3.18.6, log source = /proc/kmsg started.
