Hi Patrick,
The event log size of 3/5 MDS is also very high, still. mds.1, mds.3, and mds.4 report between 4 and 5 million events, mds.0 around 1.4 million and mds.2 between 0 and 200,000. The numbers have been constant since my last MDS restart four days ago.
I ran your ceph-gather.sh script a couple of times, but dumps only mds.0. Should I modify it to dump mds.3 instead so you can have a look? Yes, please.
The session load on mds.3 had already resolved itself after a few days, so I cannot reproduce it any more. Right now, mds.0 has the highest load and a steadily growing event log, but it's not crazy (yet). Nonetheless, I've sent you my dumps with upload ID b95ee882-21e1-4ea1-a419-639a86acc785. The older dumps are from when mds.3 was under load, but they are all from mds.0. I also attached a newer batch, which I created just a few minutes ago.
