Description of problem: ----------------------- Thinpool poolmetadatasize is set to 3MB and its very low. As per RHGS recommendation, thinpoolmetadatasize should have value 16GB. If storage is a concern, then 0.5% of thinpool size should be set as poolmetadatasize Version-Release number of selected component (if applicable): ------------------------------------------------------------- cockpit-ovirt-dashboard-0.12.3 How reproducible: ----------------- Always Steps to Reproduce: -------------------- 1. Start RHHI-V deployment 2. Select thinpool for bricks ( disable VDO for bricks ) Actual results: --------------- poolmetadatasize is set to 3MB Expected results: ------------------ poolmetadatasize should be 16GB (or) 0.5% of thinpoolsize, if storage is a concern Additional info: ---------------- Ideally it should be: poolmetadatasize = minimum( 16GB, 0.5% of thinpool size )
With cockpit-ovirt-dashboard-0.12.3, the poolmetadatasize is calculated correctly with various values for brick size. Not sure, on which occasion, we hit this problem. Right away, closing this bug.

Re-opening this bug as the value for poolmetadatasize lacks the UNIT and by default lvm considers that as MB <snip_from_inventory_file> - vgname: gluster_vg_sdb thinpoolname: gluster_thinpool_gluster_vg_sdb poolmetadatasize: 16 - vgname: gluster_vg_sdb thinpoolname: gluster_thinpool_gluster_vg_sdb poolmetadatasize: 16 </snip_from_inventory_file> <snip_from_var_log_messages> Mar 20 14:03:09 dhcp37-83 python: ansible-lvol Invoked with pvs=None force=False vg=gluster_vg_sdb lv=None resizefs=False state=present thinpool=gluster_thinpool_gluster_vg_sdb snapshot =None active=True shrink=False opts= --chunksize 2560K#012 --poolmetadatasize 16 --zero n size=100%FREE </snip_from_var_log_messages> The exact unit should be the same as thinpool size. 0.005 X ( thinpool_size ) unit
