> 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.
