In this case it's not so much moving data off as those PGs catching up with writes that came in duringthat interval. That said, 1.5% and taking 10 hours seems like a lot. Something's awry. `ceph df` `ceph osd df` `ceph osd df tree` `ceph osd dump | grep pool` `ceph config dump`

Well, if they were away long enough to get "out", then it is somewhat reasonable even for ~5m downtimes.
Right, but what I'm saying is that this is not what happens.
My reboot or disconnect takes < 5 minutes, and no OSD is `out` afterwards.
When I say "down for 5 minutes", I literally mean that the node goes down, comes back up, and I'm sitting in front of its terminal and observe that all OSDs are `up` and `in`.
Of course your explanation of what happens if it's `out` makes sense, but that isn't my scenario; if Ceph had 10 hours to move data off, of course I would have to expect at least 10 hours to move data back on. But it only has 5 minutes at max to move data off. _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
