5.6.4 HP StoreAll Storage Release Notes (AW549-96075, June 2013)

• The file system must be quiescent (no active I/O while a segment is being evacuated). Running
this utility while the file system is active may result in data inconsistency or loss.
• If quotas are enabled on the affected file system, the quotas must be disabled during the rebalance
operation.
To evacuate a segment, complete the following steps:
1. Identify the segment residing on the physical volume to be removed. Select Storage from the
Navigator on the management console GUI. Note the file system and segment number on the
affected physical volume.
2. Locate other segments on the file system that can accommodate the data being evacuated from
the affected segment. Select the file system on the management console GUI and then select
Segments from the lower Navigator. If segments with adequate space are not available, add
segments to the file system.
3. If quotas are enabled on the file system, disable them:
ibrix_fs -q -D -f FSNAME
4. Evacuate the segment. Select the file system on the management console GUI and then select
Tasks > Rebalancer from the lower Navigator. Click Start on the Task Summary page to open the
Start Rebalancing dialog, and then open the Advanced tab. In the Source Segments column,
select the segments to evacuate, and in the Destination Segments column, select the segments to
receive the data. (If you do not select destination segments, the data is spread among the available
segments.) Then click Evacuate source segments. The Task Summary window displays the progress
of the rebalance operation and reports any errors. If you need to stop the operation, click Stop.
5. When the rebalance operation completes, remove the storage from the cluster:
ibrix_fs -B -f FSNAME -n BADSEGNUMLIST
The segment number associated with the storage is not reused.
6. If quotas were disabled on the file system, unmount the file system and then re-enable quotas
using the following command:
ibrix_fs -q -E -f FSNAME
Then remount the file system.
