Hi all,
we had a network outage tonight (power loss) and restored network in the morning. All OSDs were running during this period. After restoring network peering hell broke loose and the cluster has a hard time coming back up again. OSDs get marked down all the time and come back later. Peering never stops.
Below is the current status, I had all OSDs shown as up for a while, but many were not responsive. Are there some flags that help bringing things up in a sequence that causes less overload on the system?
osd_recovery_delay_start
We have that set on 60 seconds. So the OSD first gets some time to peer
before starting recovery. That might help in this case. Worth a shot.
Maybe increase it to 5 minutes or more just to get all OSDs stable
before recovery starts going?
Good luck!
Gr. Stefan
