I have recently created a Thin LVM. I notice the Data is at 1.60% and Meta at 1.21%.
[root@srv ~]# lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert lv1 volgrp1 twi-aotz-- 410.00g 1.60 1.21
I have three questions:
- Is this Meta size expected. (almost equivalent to Data)
- Is it recommended to reduce/set metadata to a smaller value (using --poolmetadatasize).
- Are there any performance impact / concerns by setting a lower metadata size.
I appreciate your kind advice on this.
