Description

FSE backup fails and the following entries are reported to the terminal window and logged in

 

the backup.log file (the volume and partition names may be different):

 

[2006/03/02 22:39:20] Volume /dev/vg_fse/part: Creating snapshot...

 

[2006/03/02 22:39:20] ERROR: SnapshotsMgr error.

 

[2006/03/02 22:39:20] Unsuspending partition...

 

[2006/03/02 22:39:20] Partitions fs1: Unsuspended.

 

[2006/03/02 22:39:20] Finished unsuspending for all partitions.

 

[2006/03/02 22:39:20] Backup job stopped.

 

[2006/03/02 22:39:20] ERROR: Backup failed: 9, Creating snapshot /dev/vg_fse/part failed!

 

Return value 3

 

 

(SUSE Linux Enterprise Server system specific)

Explanation

The module dm-snapshotwas not loaded at the time when FSE backup tried to create

 

volume snapshots.

 

Workaround

You need to load the module and configure its automatic loading at subsequent system

 

startups.

 

 

To load the module, invoke the following command:

 

# modprobe dm-snapshot

 

 

To configure automatic loading of the module at subsequent system startups, add the string

 

dm-snapshot to the variable MODULES_LOADED_ON_BOOT in the file

 

/etc/sysconfig/kernel, like shown in the following example:

 

## Type:

string

 

## ServiceRestart:

boot.loadmodules

 

#

 

#This variable contains the list of modules to be loaded

#once the main filesystem is active

#

MODULES_LOADED_ON_BOOT="dm-snapshot"
