Data goes to *all* PGs uniformly. Max_avail is limited by the available space on the most full OSD -- you should pay close attention to those and make sure they are moving in the right direction (decreasing!)
Another point -- IMHO you should aim to get all PGs active+clean before you add yet another batch of new disks. While there are PGs backfilling, your osdmaps are accumulating on the mons and osds -- this itself will start to use a lot of space, and active+clean is the only way to trim the old maps. -- dan On Tue, Mar 23, 2021 at 7:05 PM Boris Behrens <b...@kervyn.de> wrote: > > So, > doing nothing and wait for the ceph to recover? > > In theory there should be enough disk space (more disks arriving tomorrow), > but I fear that there might be an issue, when the backups get exported over > night to this s3.
