Hi Zheng,
I did some more tests with cephfs-table-tool. I realized that disaster
recovery implies to possibly reset inode table completely besides doing
a session reset using something like
cephfs-table-tool all reset inode
Would that be close to what you suggested? Is it safe to reset complete
inode table or will that wipe my file system?
Btw. cephfs-table-tool show reset inode gives me ~400k inodes, part of
them in section 'free', part of them in section 'projected_free'.
Thanks,
Tobi

These are essentially the first commands I did execute, in this exact order.
Additionally I did a:
ceph fs reset cephfs --yes-i-really-mean-it
how many active mds were there before the upgrading.
Any hint on how to find max inode number and do I understand that I should
remove every free-marked inode number that is there except the biggest one
which has to stay?
If you are not sure, you can just try removing 10000 inode numbers
from inodetale
How to remove those inodes using cephfs-table-tool?
using cephfs-table-tool take_inos <max ino>
