After you install NSS and create NSS pools on a device, make sure to use EVMS to manage any other types of file system partitions on that device, such as EXT3, ReiserFS, or other Linux traditional file systems. Continue to use NSSMU or the iManager Storage plug-in as the preferred methods of managing NSS pools and volumes on OES Linux.
If you use another volume manager, your system can become unbootable. During the partition creation process, the YaST partitioner modifies the /etc/fstab configuration file to incorrectly identify NSS pools as EXT2 partitions instead of NSS partitions. For example, a command like this is added to the /etc/fstab file for each NSS pool:
/dev/evms/MYPOOL /nss/.pools/MYPOOL ext2 defaults 1 2
To work around this problem when using the YaST partitioner, after you create a Linux traditional file system and before you reboot your system, edit the /etc/fstab file to remove or comment out the lines that identify NSS partitions as ext2 partitions.
To recover your system if you reboot your server before editing the /etc/fstab file:
Boot your OES Linux server in Single User mode.
Mount the root file system with remount and read/write options. At the command console, enter
mount -n -o remount,rw /
Edit the /etc/fstab file to remove or comment out the lines that identify NSS partitions as ext2 partitions.
Reboot the server.
