Troubleshooting file systems 9–27
2. Stop the file system and ensure that the file system devices are not being used. Check the /proc/
mounts file and the /proc/fs/lustre/obdfilter/mntdev (or /proc/fs/lustre/mds/
mntdev) files to ensure that the file system devices are not mounted on any mount point.
3. Ensure that the administration server can connect to all of the other servers used by the file systems
using the ssh utility without a password.
4. Enter the name of the generated script at the prompt, as shown in the following example:
# do_lfsck-scratch.sh
When the repair process is complete, make sure that there are no stray mount points remaining mounted
before you start the file system.
If a do-lfsck-filesystem_name script fails for any reason, HP recommends that you contact your HP
Customer Support representative. Ensure that there are no stray processes or mounts left mounted. You can
see mounts, (with the name /mnt/device.x), in the /proc/mounts file on the servers. Note that these
mounts are not shown by the mount(8) command. Rebooting the servers will ensure that stray processes
and mounts are cleared.
9.26.5.2 Repairing or verifying individual MDS or OST services
If you want to repair or verify MDS or OST services themselves (rather than an entire file system), you can
run the e2fsck-lfsck command manually using the same arguments as would be used by the standard
e2fsck program to repair a standard ext3/ldiskfs file system.
Note that if the device you want to examine or repair is a mirrored device, you must start the underlying
mirrored devices before you run the e2fsck-lfsck command.
Before you run the e2fsck-lfsck command manually, perform the following steps:
1. Identify the device that the e2fsck-lfsck command is to examine. The device names are made up
as follows:
/dev/hpls/devlun_numbera
where lun_number is the number of the LUN used by the service.
Use the show filesystem filesystem_name command to identify the LUN numbers for the
devices. In the following example, the file system name is test, the MDS device name is /dev/
hpls/dev5a, and the OST device names are /dev/hpls/dev1a and /dev/hpls/dev2a:
sfs> show filesystem test
Name: test
OSTs: ost[7-8]
State: started
Mountpoint: /mnt/test/
Stripe size: 4194304
Stripe count: 2
Interconnect: tcp elan
MDS mount options: acl,user_xattr
OST mount options: extents
Lustre timeout: 200
Quota options: quotaon=ug
