Hi all,

HEALTH_WARN 3 pgs incomplete; 3 pgs stuck inactive; 3 pgs stuck unclean
pg 24.cc is stuck inactive for 595902.285007, current state incomplete,

Hi,
you can also set the primary_affinity to 0.5 at the 8TB-disks to lower
the reading access (in this case you don't waste 50% of space).

Hi,

http://ceph.com/releases/v10-2-10-jewel-released/ isn't found.
No announcement on the mailing list (perhaps i miss something).
I know, normaly it's save to update ceph, but two releases ago it
wasn't.

no ceph read from the primary PG - so your reads are app. 33% local.
