Hi, thanks for your help.
I am using ceph Pacific 16.2.7.
Before my Ceph stuck at `ceph fs status fsname`, one of my cephfs became readonly.
Probably the ceph-mgr is stuck (the "volumes" plugin) somehow talking to the read-only CephFS. That's not a scenario we've tested well.
The metadata pool of the readonly cephfs grew up from 10GB to 3TB. Then I shut down the readonly mds.
Your metadata pool grew from 10GB to 3TB in read-only mode? That's unbelievable! We would need a lot more information to help figure the cause. Such as: `ceph tell mds.X perf dump`, `ceph tell mds.X status`, `ceph fs dump`, and `ceph tell mgr.X perf dump` while this is occurring. -- Patrick Donnelly, Ph.D. He / Him / His Red Hat Partner Engineer IBM, Inc.
