Reclaiming space on a file system


Reclaiming space on a file system
Prev	Maintaining Thin Storage with Thin Reclamation	Next

This section describes how to trigger space reclamation on a file system. You can perform a default space reclamation, or aggressive reclamation. Thin Reclamation is only supported on VxFS file systems mounted on a VxVM volume.

Thin Reclamation is not supported for file systems mounted on RAID5 volumes.

To trigger aggressive space reclamation

Ensure you mounted the VxFS file system.
See the mount(1M) manual page.

If you need to mount the VxFS file system, see the mount_vxfs(1M) manual page.
Use the following command to perform aggressive reclamation of free storage to the Thin Storage LUN on a VxFS file system mounted at /mnt1:
```
# /opt/VRTS/bin/fsadm -R -o aggressive /mnt1
```

To trigger space reclamation

Ensure you mounted the VxFS file system.
See the mount(1M) manual page.

If you need to mount the VxFS file system, see the mount_vxfs(1M) manual page.
Use the fsadm command to trigger space reclamation:
```
# /opt/VRTS/bin/fsadm -t vxfs -R /<VxFS_mount_point>
```
where <VxFS_mount_point> is the name of the VxFS file system mount point.

Note:

If the VxFS file system is not mounted you will receive an error message. For example: Disk 3pardata0_110 : Skipped. No VxFS file system found.
