Description of problem:
Thinpool block zero should be skipped while setting up LVM for RHHI.
However, when backend setup is done using gdeploy, block zeroing is happening.
The configuration file to test:
$ cat backend.conf
The output should look like:
[root@rhs31-c ~]# dmsetup table
RHS_vg1-GLUSTER_pool: 0 104800256 thin-pool 253:2 253:3 512 0 1 skip_block_zeroing
RHS_vg1-GLUSTER_pool_tdata: 0 104800256 linear 252:32 25088
RHS_vg1-GLUSTER_pool_tmeta: 0 24576 linear 252:32 104825344
rhgs_dhcp41--223-swap: 0 4194304 linear 252:2 2048
rhgs_dhcp41--223-root: 0 35643392 linear 252:2 4196352
With skip_block_zeroing for the lv created by gdeploy.
Patch posted at: https://github.com/gluster/gdeploy/pull/520
Tested with gdeploy-2.0.2-31.el7rhgs
Now thinpool zeroing is skipped while creating thinpool using gdeploy conf file as mentioned in comment0
[root@ ~]# dmsetup table | grep -i zero
gluster_vg_sdd-gluster_thinpool_sdd-tpool: 0 4294967296 thin-pool 253:15 253:16 2048 0 1 skip_block_zeroing
