Description
Array experienced a power loss or crash during the mount operation. The filesystem does not appear in diagnostic email and is inaccessible via NFS/CIFS, underlying raid volume remains up and active.



Steps to Follow
The most common reason for the mount failure is a power loss or crash during the mount process. This causes a "mount failure" flag to be set on the volume. When the Sun StorEdge[TM] 5x10 NAS Appliance encounters this flag upon boot, it does not mount the volume, and logs the following message:
<Date> <Time> I sfs2: /volume - id=4D9721D3, extent 1 of 3, version 2
<Date> <Time> I sfs2: /volume - id=4D9721D3, extent 2 of 3, version 2
<Date> <Time> I sfs2: /volume - id=4D9721D3, extent 3 of 3, version 2
<Date> <Time> I /[2] fruitless bitmap 168 bytes
<Date> <Time> I /[1] fruitless bitmap 252 bytes
<Date> <Time> I /volume[0] fruitless bitmap 252 bytes
<Date> <Time> A /volume not mounted, previous mount did not complete. <----
<Date> <Time> A dpmgr: Error sfs2-mount isp1d020,3

In some cases, the bootlogs may not contain the original failure because too much time had passed. All subsequent unsuccessful attempts to mount the volume will log the same error message "previous mount did not complete".

The LunPath Information should show that the device is up and active.

Dasdid 600 isp1d020 has 2 paths, Owner Real 1 Current 1
P1: isp1d020 status(3) UP ACTIVE
P2: isp3d000 status(1) UP

If it is 100 percent certainty that the problem is an interrupted mount attempt, the filesystem will need to be force mounted and fsck'd. fsck can only run if the filesystem is mounted.

CLI command "mount -f /volume"

Check the log again to confirm that the filesystem mounted, and run fsck.
