okay, i run this command: rados rm -p cephfs_metadata mds0_openfiles.0
start the MDS daemons and the "Malformed input" error seems to fixed. i
have 3 MDS daemons, two of them are running in "standby" modus and the
active one (pve04) is restarting in an endless loop with the attached
log output.
I have read a couple of threads about duplicate inodes. And like Dan
said [1] "The developer at that time suggested some manipulations to
remove the omap entries for the older version of the inode from the
stray dirs, and also to eventually run cephfs-data-scan scan_links."
But ... in your log the object id is not printed
"mds.0.cache.dir(0x100) _fetched badness: got (but i already had)
[inode 0x600 [...2,head] ~mds0/stray0/ auth v10386"
I would have expected the object right after ~mds0/stray0/. So I'm
unsure how to find the right omap entry to delete.

by the way, my complete "proxmox stack" is now out of service? the
simple output is "failed to mount /mnt/pve/cephfs". so, do you see an
another step to fix my problem?

sounds bad! what does it mean? can we fixed it?
If you still have any clients that have (or try to) mount CephFS, umount
them for now.
AFAIK you cannot fix this, but you can remove it (it's corrupt anyway):
- Stop all the MDSes.
- rados rm -p cephfs_metadata mds0_openfiles.0. This is more or less
harmless [1]
Not sure if that is the only issue, but you will find out after you
start an MDS and try to mount it from a client.
