Acronis Advanced Backup for Linux Backup from LVM snapshot
Hello all,
Decided to give the "LVM snapshotting" option under backup job parameters a try. My VMs are basically just LVMs so it should be just as good as a snapshot created by Acronis kernel module. I also made sure that the volume group in which the logical volume to back up is located, has more than 10% free space. Unfortunately it does not work; the management server reports job error with the following details:
--------------------
Error code: 33
Module: 7
LineInfo: df81da2c74ec50a2
Fields: $module : disk_bundle_lxa64_pic_44421
Message: Failed to create volume snapshot.
--------------------
Error code: 1
Module: 89
LineInfo: 7ab2eca390dee24c
Fields: device : /dev/mapper/vg_ol6-testlvm, $module : disk_bundle_lxa64_pic_44421
Message: Common I/O error.
But what it even more interesting is that a new logical volume (testlvm_acronis_snapshot, to my surprise not an LVM snapshot(!)) is created on the backup target in the same volume group as the logical volume to back up:
--- Logical volume ---
LV Name /dev/vg_ol6/testlvm

This is actually contrary to what's stated in the user manual; that LVM snapshots are created using the lvcreate -s command.
Same behavor on Acronis advanced 11.5 and 11.7.
Has anyone succeeded in creating LVM snapshot-based backups?
