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. In the following example, physical volume d1 is being retired. Segment
1 from file system ifs1 uses that 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. In this example, the data from segment 1 will be evacuated to segments
2 and 3.
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:
