Comment 1 SATHEESARAN 2017-09-21 12:22:43 UTC

This bug is actually cloned from the RHHI 1.1 bug which directly corresponds to the failure of gdeploy in creating lvmcache backed LVs

Comment 2 Sachidananda Urs 2017-09-22 07:27:25 UTC

Commit: https://github.com/gluster/gdeploy/commit/be2c9ddbecb47c fixes the issue.

Comment 3 SATHEESARAN 2017-09-22 15:58:30 UTC

Verified with gdeploy-2.0.2-16.el7rhgs and this issue is not seen.

The configuration file used is:
[lv]
action=setup-cache
ssd=vde
vgname=vg
poolname=thinpool
cache_lv=lvcache
cache_lvsize=5GB
cachemode=writeback

This setup the lvmcache as required.

Note:
Not marking this bug as **VERIFIED** as the gdeploy errata is not yet available.
Once the gdeploy errata is available with this specified build, I will move this bug to VERIFIED state.

Comment 4 SATHEESARAN 2017-09-28 07:54:17 UTC

The build - gdeploy-2.0.2-16.el7rhgs is available with the errata and with comment3 marking this bug as VERIFIED
