Dear CEPHers, Adding some comments to my colleague's post: we are running Mimic 13.2.6 and struggling with 2 issues (that might be related): 1) After a "lack of space" event we've tried to remove a 40TB file. The file is not there anymore, but no space was released. No process is using the file either. 2) There are many files in /lost+found (~25TB|~5%). Every time we try to remove a file, MDS crashes ([1,2]). The Dennis Kramer's case [3] led me to believe that I need to recreate the FS. But I refuse to (dis)believe that CEPH hasn't a repair tool for it. I thought "cephfs-table-tool take_inos" could be the answer for my problem, but the message [4] were not clear enough. Can I run the command without resetting the inodes?
