Full Discussion: NFS mounts query
Operating Systems Linux Red Hat NFS mounts query Post 302873241 by Peasant on Monday 11th of November 2013 11:46:20 AM

You can have that same ext3 partition on SAN, using lvm.

On node1 it's active (volume group is activated), on other it is not.
If things fail on node1, you can activate the volume group on node2 and mount the filesystem.

You need to reconfigure your backup to take it from local disk, instead of NFS mount.

Do not have entries in /etc/fstab or scripts that activate / mount it automatically (that is what clusters are for.)

If you have clusterware, check if you can configure a simple disk resource for that disk/volume group.

Hope that helps
Regards
Peasant.

NAME
vgcfgbackup - backup volume group descriptor area SYNOPSIS
vgcfgbackup [-d|--debug] [-f|--file filename] [-h|--help] [--ignorelockingfailure] [-P|--partial] [-v|--verbose] [VolumeGroupName...] DESCRIPTION
vgcfgbackup allows you to backup the metadata of your volume groups. If you don't name any volume groups on the command line, all of them will be backed up. In a default installation, each volume group gets backed up into a separate file bearing the name of the volume group in the directory /etc/lvm/backup. You can write the backup to an alternative file using -f. In this case if you are backing up more than one volume group the filename is treated as a template, and %s gets replaced by the volume group name. NB. This DOESN'T backup user/system data in logical volume(s)! Backup /etc/lvm regularly too. OPTIONS
See lvm for common options. SEE ALSO
