I had 2 MDS servers (one active one standby) and both were down. I took a dumb chance and marked the active as down (it said it was up but laggy). Then started the primary again and now both are back up. I have never seen this before I am also not sure of what I just did.

I was creating a new user and mount point. On another hardware node I mounted CephFS as admin to mount as root. I created /aufstest and then unmounted. From there it seems that both of my mds nodes crashed for some reason and I can't start them any more.

I have never had this happen in my tests so now I have live data here. If anyone can lend a hand or point me in the right direction while troubleshooting that would be a godsend!
I tried cephfs-journal-tool inspect and it reports that the journal should be fine. I am not sure why it's crashing:/home/lacadmin# cephfs-journal-tool journal inspectOverall journal integrity: OK
