Hello All,
This might be some basic mistake I would be doing with respect to different poolmetadata size.
When I am trying to create thinpool with poolmetadatasize as 4m it fails but similar is successful when I try to create with 5m. Default poolmetadatasize can be 2m to 16g so I am not sure what is error I am enforcing it to fail.
Kindly help me out with this issue.
Case 1: poolmetadatasize as 4m
#script to create thinpool with poolmetadatasize 4m
[root@rahul ~]# cat temp
pvcreate /dev/vdb
pvcreate /dev/vdc
pvcreate /dev/vdd
pvcreate /dev/vde
vgcreate snap_vg0 /dev/vdb /dev/vdc /dev/vdd /dev/vde
lvcreate -L 90G --poolmetadatasize 4m -T /dev/snap_vg0/snap_thin_pool0
#lvcreate -L 90G -T /dev/snap_vg0/snap_thin_pool0
lvcreate -V90G -T /dev/snap_vg0/snap_thin_pool0 -n snap_thin_vol0
[root@rahul ~]#
[root@rahul ~]#
Case 2: poolmetadatasize as 5m
#script to create thinpool with poolmetadatasize 5m
[root@rahul ~]# cat temp
pvcreate /dev/vdb
pvcreate /dev/vdc
pvcreate /dev/vdd
pvcreate /dev/vde
vgcreate snap_vg0 /dev/vdb /dev/vdc /dev/vdd /dev/vde
lvcreate -L 90G --poolmetadatasize 5m -T /dev/snap_vg0/snap_thin_pool0
#lvcreate -L 90G -T /dev/snap_vg0/snap_thin_pool0
lvcreate -V90G -T /dev/snap_vg0/snap_thin_pool0 -n snap_thin_vol0
