Troubleshooting file systems
ibrix_pv -a discovers too many or too few devices
This situation occurs when file serving nodes see devices multiple times. To prevent this, modify
the LVM2 filter in /etc/lvm/lvm.conf to filter only on devices used by X9000 Software. This
will change the output of lvmdiskscan.
By default, the following filter finds all devices:
filter = [ "a/.*/" ]
The following filter finds all sd devices:
filter = [ "a|^/dev/sd.*|", "r|^.*|" ]
Contact HP Support if you need assistance.
Cannot mount on an X9000 client
Verify the following:
•
The file system is mounted and functioning on the file serving nodes.
•
The mountpoint exists on the X9000 client. If not, create the mountpoint locally on the client.
•
Software management services have been started on the X9000 client (see “Starting and
stopping processes” in the administration guide for your platform).
NFS clients cannot access an exported file system
An exported file system has been unmounted from one or more file serving nodes, causing X9000
Software to automatically disable NFS on those servers. Fix the issue causing the unmount and
then remount the file system.
User quota usage data is not being updated
Restart the quota monitor service to force a read of all quota usage data and update usage counts
to the file serving nodes in your cluster. Use the following command:
/bin/ibrix_qm restart
SegmentNotAvailable is reported
When writes to a segment do not succeed, the segment status may change to
SegmentNotAvailable
on the GUI and an alert message may be generated. To correct this
situation, take the following steps:
