Hi, I've been backing up using rsnapshot directly on my running system. I recently decided to begin doing this properly, and to use LVM's snapshot facility, so I wrote a basic, simple script to encapsulate the rsnapshot call with LVM snapshot creation, mounting, umounting, and removal:
#! /bin/sh /sbin/lvcreate -L 2G -s -n home_backup /dev/lizzie/home /sbin/lvcreate -L 100M -s -n root_backup /dev/lizzie/root /sbin/lvcreate -L 1G -s -n var_backup /dev/lizzie/var /bin/mount /dev/lizzie/home_backup /mnt/home_backup/ /bin/mount /dev/lizzie/root_backup /mnt/root_backup/ /bin/mount /dev/lizzie/var_backup /mnt/var_backup/ /usr/bin/rsnapshot $1 /bin/umount /mnt/home_backup/ /bin/umount /mnt/root_backup/ /bin/umount /mnt/var_backup/ /sbin/lvremove -f lizzie/home_backup /sbin/lvremove -f lizzie/root_backup /sbin/lvremove -f lizzie/var_backup Originally this ran cleanly, but I've begun to see errors. The last run, for example, produced this in the removal stage: Logical volume "home_backup" successfully removed /dev/block/254:13: stat failed: No such file or directory Path /dev/block/254:13 no longer valid for device(254,13) /dev/mapper/lizzie-home-real: stat failed: No such file or directory Path /dev/mapper/lizzie-home-real no longer valid for device(254,13) /dev/disk/by-id/dm-name-lizzie-home-real: stat failed: No such file or directory Path /dev/disk/by-id/dm-name-lizzie-home-real no longer valid for device(254,13) /dev/disk/by-id/dm-uuid-LVM-J0Vt1p4hrMWMgX0RTSCuurCGzEF8QgK7ryR1QntEe5bmluEs3y8T03MEpi3eAWpW-real: stat failed: No such file or directory Path /dev/disk/by-id/dm-uuid-LVM-J0Vt1p4hrMWMgX0RTSCuurCGzEF8QgK7ryR1QntEe5bmluEs3y8T03MEpi3eAWpW-real no longer valid for device(254,13) Logical volume "root_backup" successfully removed /dev/block/254:16: stat failed: No such file or directory Path /dev/block/254:16 no longer valid for device(254,16) /dev/disk/by-id/dm-name-lizzie-root-real: stat failed: No such file or directory Path /dev/disk/by-id/dm-name-lizzie-root-real no longer valid for device(254,16) /dev/mapper/lizzie-root-real: stat failed: No such file or directory Path /dev/mapper/lizzie-root-real no longer valid for device(254,16) /dev/disk/by-id/dm-uuid-LVM-J0Vt1p4hrMWMgX0RTSCuurCGzEF8QgK7vm806jRQCqyOajf8BIbDlvppK22X6gaL-real: stat failed: No such file or directory Path /dev/disk/by-id/dm-uuid-LVM-J0Vt1p4hrMWMgX0RTSCuurCGzEF8QgK7vm806jRQCqyOajf8BIbDlvppK22X6gaL-real no longer valid for device(254,16) Logical volume "var_backup" successfully removed And in syslog, I see this (no idea if it's related): Mar 5 01:58:44 localhost kernel: [108498.500356] kjournald starting.
