[ceph-users] MAX AVAIL goes up when I reboot an OSD node

Dear people on this mailing list, I've got the "problem" that our MAX AVAIL value increases by about 5-10 TB when I reboot a whole OSD node. After the reboot the value goes back to normal. I would love to know WHY. Under normal circumstances I would ignore this behavior, but because I am very new to the whole ceph software I would like to know why stuff like this happens. What I read is, that this value will be calculated by the most filled OSD. I've set noout and norebalance while the node is offline and I unset both values after the reboot. We are currently on nautilus. Cheers and thanks in advance Boris
