Description Sahina Bose 2016-04-11 11:10:50 UTC

Description of problem:

If SSD devices are available on server, it should be possible to use this device as lvmcache and attach it to a thinpool device.

gdeploy should provide the user the flexibility to configure this as part of brick provisioning

Version-Release number of selected component (if applicable):
3.1

How reproducible:
NA

Comment 3 SATHEESARAN 2016-05-11 10:30:36 UTC

lvs section has got a action 'setup-cache' which setups the dm-cache

[lvs]
action=setup-cache
ssd=sdc
poolname=lvpool1
vgname=rhgs_vg1
cache_lvsize=10GB

the above section helps in the creation of dm-cache ( lvmcache ) if ssd is available
