Re: [ceph-users] cephfs miss data for 15s when master mds rebooting

hi John thanks for your answer. in normal condition, i can run "ceph mds fiail" before reboot. but if the host reboots by itself for some reason, i can do nothing! if this happens, data must be losed. so, is there any other way to stop data from being losed? thanks 13605702.
