This article describes how to workaround to resolve the below error during failback of SLES version 9 workload.
could not add partition /dev/sda1 to monitoring list: Unable to find mountpoint for "/dev/sda1" PATH is :/lib/modules/2.6.5-7.97-default/platespin/blkwatch.ko using /dev/blkwatch_1355 device, errno: 0


1. Manually modify /etc/fstab to use device-name instead of UUID.
For Example: 
A sample of /etc/fstab with UUID:
UUID=b37fa7c6-ad26-4b65-8760-6467701e7e79  /    reiserfs    acl,user_xattr    1 1
Assuming its known that UUID b37fa7c6-ad26-4b65-8760-6467701e7e79 relates to /dev/sda1, then the line above should be changed to as follows:
/dev/sda1  /    reiserfs    acl,user_xattr    1 1
To view the relation between device name and UUID run the blkid command. Below is a sample output:
# blkid
/dev/sda1: UUID="b37fa7c6-ad26-4b65-8760-6467701e7e79" TYPE="reiserfs"
/dev/sda2: TYPE="swap"
2. Remount all volumes involved or reboot the source workload if the remount command throws an error as volumes are busy.
3. Remove the workload and readd from scratch.


SLES version 9 has the root ("/") not listed in "/proc/mounts". This causes the lookup (Device-Name => MountPoint) to return null value, hence operation fails.
