Description
Since we upgraded from firefly to hammer the MAX AVAIL column is quite wrong for most of our pools.
GLOBAL:
SIZE AVAIL RAW USED %RAW USED
3564T 2544T 1020T 28.61
Example pool:
POOLS:
NAME ID USED %USED MAX AVAIL OBJECTS
volumes 4 255T 7.17 272T 67556416
By my calculations MAX AVAIL should be 2184T/3 = 728T.
