Hi folks,
my cluster shows strange behavior, the only ssd pool on cluster with repsize 3 and pg/pgp size 512
which contains 300GB rbd image and only one snapshot occupies 11TB space!
I have tried objectmap check / rebuild, fstrim etc. which couldn’t solve that problem, any help would be appreciated.
