Hey folks,
I have deployed a 3 node dev cluster using cephadm. Deployment went
smoothly and all seems well.
If I try to mount a CephFS from a client node, 2/3 mons crash however.
I've begun picking through the logs to see what I can see, but so far
other than seeing the crash in the log itself, it's unclear what the cause
of the crash is.
Here's a log. <https://termbin.com/isaz>. You can see where the crash is
occurring around the line that begins with "Jun 08 18:56:04 okcomputer
podman[790987]:"
Hi Phil,
I assume you are mounting the kernel client, not ceph-fuse? If so,
what is the kernel version on the client node?
ceph version 16.2.4 (3cbe25cde3cfa028984618ad32de9edc4c1eaed0)
pacific (stable)
