Oracle Linux 7 mounting SAN storage issue
I have a scenario where I am trying to mount SAN storage to my linux machine. My environment details are-
- Oracle VM manager for VM creation
- Fiber Channel HP3PAR SAN storage attached as physical disk to my VM
- Oracle Linux version -OEL 7.4
Below steps I have been doing as earlier worked smoothly but not now-
- Login as root user on VM Running
fdisk utility to check attached disks
fdisk -l
It shows 2 disks /dev/xvdb & /dev/xvdc where /dev/xvdc appeared after attaching the SAN storage to VM.
Applying mount command to mount /dec/xvdc on location
/u01/oracle/config where /u01/oracle/config is empty
mount /dev/xvdc /u01/oracle/config
After this the command screen cursor just blinks and nothing
happens.
Further I have checked whether the mount was successful, no it is not. Running the command 'df -h' and 'mount' doesn't shows the storage was mounted to requested location.

Problem solved. The issue was associated with disk log corruption.
So I tried to repair the disk using below steps-
xfs_repair /dev/xvdc
a warning indicated as specified below
Phase 1 - find and verify superblock...
Phase 2 - using internal log
- zero log...
ERROR: The filesystem has valuable metadata changes in a log which needs to
be replayed. Mount the filesystem to replay the log, and unmount it before
re-running xfs_repair. If you are unable to mount the filesystem, then use
the -L option to destroy the log and attempt a repair.
Note that destroying the log may cause corruption -- please attempt a mount
of the filesystem before doing this.
So further, I proceeded with below steps-
xfs_repair -L /dev/xvdc
mount -t xfs /dev/xvdc /u01/oracle
This successfully mount disk /dev/xvdc to location /u01/oracle.
NOTE : I have formatted the disk using XFS file system earlier.
