Hi Frank, I have not experienced this before. Maybe mds.tceph-03 is in standby state? Could you show the output of “ceph fs status”? You can also try “ceph tell mds.0 …” and let ceph find the correct daemon for you. You may also try dumping “~mds0/stray0”.

Whatever I try, I cannot figure out how to pull the root inode into the MDS cache - if this is even the problem here. I also don't understand why the annoying ms_handle_reset messages are there.

I have ca. 1mio stray entries and they must be somewhere. mds.tceph-03 is the only active MDS. > > Can someone help me out here? > > Thanks and best regards, > ================= > Frank Schilder > AIT Risø Campus > Bygning 109, rum S14 > _______________________________________________ > ceph-users mailing list -- ceph-users@xxxxxxx > To unsubscribe send an email to ceph-users-leave@xxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
