I was posting with my office account but I think it is being blocked.
Our cephfs's metadata pool went from 1GB to 1TB in a matter of hours and after using all storage on the OSD's reports two damaged ranks.
The cephfs-journal-tool crashes when performing any operations due to memory utilization.
We tried a backup which crashed (we then did a rados cppool to backup our metadata).
I then tried to run a dentry recovery which failed due to memory usage.
Any recommendations for the next step?
