I still got this major issue that automatic nightly snapshoting is absolutly not reliable. In 4 out of 5 times the snapshoting will fail.
HP DL320s box with 6 harddisks
Ubuntu server 7.04 (feisty)
device-mapper: ioctl: 4.11.0-ioctl (2006-10-12) initialised: dm-devel redhat com
LVM version: 2.02.06 (2006-05-12)
Library version: 1.02.08 (2006-07-17)
Driver version: 4.11.0
All my disks form a big hardware RAID5. LVM is serving one volume group with 4 logical volumes. To of the volumes have the XFS filesystem and should be snapshot every night.
Therefor I unmount the last snapshot, remove the snapshot and the re-create it with the same name. But it looks like lvm isn't removing the snapshot most of the time. The lvremove returns that it has successfully removed the snapshot. But when I try to re create the snaphost it fails. Then with "lvs" I can see that the snapshot is still there.
I tried to deactivate the snapshot prior to removing with "lvchange -an" but that wont help or even work most of the times.
Has someone a working konfiguration? Home often do you snapshots? Could this be a XFS issue?
thanks and kind regards
