undo lvm snapshot recovery
Hi all,
have a bit of a situation after a failed backup procedure using LVM-snapshot. normally i have a script running to make backups each night of my Logical Volume, i create a snapshot of the volume and then use rsnapshot to make a backup and then remove the snapshot again, been going well for years. untill the backup of wednesday got jammed and the script never fully completed leaving the snapshot in place (i know its my bad, should use more sanity checks in my script) i didn't really notice anything gone bad till saturday when all te requests to my server were timing out and after logging in i noticed it was under 100% load and did a reboot, all fine till i noticed that i was missing several days, in fact the whole machine rolled back to the state since the last complete backup. the logs were showing io errors to the snapshot, probably being full. not sure if all is lost or if there is a way to recover this lost data. Code:
vgcfgrestore --list drbdvg0 Code:
vgcfgrestore -f /etc/lvm/archive/drbdvg0_00158.vg drbdvg0 Code:
mount: special device /dev/drbdvg0/backup does not exist need to wait now for doing a full backup of its current state before attempting to merge back the snapshot, IF at all possible, since i have no idea yet on what procedure to follow. anybody here an idea on how to release me from this agony? much obliged |
