3.7. Changing the compression and deduplication settings on an LVM-VDO volume

Procédure

1. To find out if the compression and deduplication is enabled or disabled on your logical volumes:

   # lvs -o+vdo_compression,vdo_deduplication

2. Find out status of the compression and status of the deduplication index of your running active VDOPoolLV:

   # lvs -o+vdo_compression_state,vdo_index_state

   The vdo_index_state can show as error, close, opening, closing, online, and offline.

3. To enable or disable the compression for VDOPoolLV:

   # lvchange --compression y|n  vg-name/vdopoolname

4. To enable or disable the deduplication for VDOPoolLV:

   # lvchange --deduplication y|n vg-name/vdopoolname
