Thank you very much !
Is this problem then related to the weird sizes I see:
pgmap v55220: 1216 pgs, 3 pools, 3406 GB data, 852 kobjects
418 GB used, 88130 GB / 88549 GB avail
a calculation with df shows indeed that there is about 400GB used on
disks, but the tests I ran should indeed have generated 3,5 TB, as
also seen in rados df:
pool name category KB objects clones
degraded unfound rd rd KB wr
wr KB
cache - 59150443 15466 0
0 0 1388365 5686734850 3665984
4709621763
ecdata - 3512807425 857620 0
0 0 1109938 312332288 857621
3512807426
I thought it was related to the inconsistency?
Or can this be a sparse objects thing? (But I don't seem to found
anything in the docs about that)
Thanks again!
Kenneth
