Hello,
os: ubuntu bionic lts
ceph v12.2.7 luminous (on one node we updated to ceph-mds 12.2.8 with no luck)
2 mds and 1 backup mds
we just experienced a problem while restarting a mds. As it has begun to replay the journal, the node ran out of memory.
A restart later, after giving about 175GB of swapfile, it still breaks down.
As mentioned in an maillist entry with similar problem earlier, we restarted all mds nodes causing all nodes to leak. Now they just switch around as they break down and the backup starts the replay.
Sincerely
Patrick
