Subject: Re: [ceph-users] Clear health warning
Right, so you have 3 active MDS's and 0 on standby, which is generating a (correct)
health warning. You need to either add more MDS' to be standbys, or reduce the fs to 2
active MDS'.

How many MDS's do you have total, and how are they assigned? 'ceph fs

Hi, (nautilus, 14.2.8, whole cluster)
I doodled with adding a second cephfs and the project got canceled. I removed the unused
cephfs with "ceph fs rm dream --yes-i-really-mean-it" and that worked as
expected. I have a lingering health warning though which won't clear.
The original cephfs1 volume exists and is healthy:
[root@cephmon-03]# ceph fs ls
name: cephfs1, metadata pool: stp.cephfs_metadata, data pools: [stp.cephfs_data ]
[root@cephmon-03]# ceph mds stat
cephfs1:3 {0=cephmon-03=up:active,1=cephmon-02=up:active,2=cephmon-01=up:active}
[root@cephmon-03]# ceph health detail
HEALTH_WARN insufficient standby MDS daemons available
MDS_INSUFFICIENT_STANDBY insufficient standby MDS daemons available
have 0; want 1 more
[root@cephmon-03]#
I have not yet deleted the pools for 'dream', the second cephfs definition. (There
is nothing in it.)
Before deleting the pools is there a command to clear this warning?
Thanks!
