Yes, I have all MDS running now and I am in the process of building ceph sources with your patch from the original thread. I also tried the command: ceph fs compat prod add_incompat 7 "mds uses inline data" Since I noticed that option was defined for two of the three file systems (the working ones) and not for the down / failed file system. That seemed to have no effect, I will try addfailed once I am done building ceph-mon. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
