MDS is Readonly

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



 

We have ceph 12.2.4 cephfs with two active MDS server and directory are  pinned  to MDS servers. Yesterday MDS server crashed.  Once all fuse clients have  unmounted, we bring back MDS online. Both MDS are active now.

 

Once It came back, we started to see one MDS is   Readonly.

It health waring I see

    health: HEALTH_WARN

            1 MDSs are read only

            1 MDSs behind on trimming

 

There is no error on OSDs on metadata pool

Will ceph daemon mds.x scrub_path / force recursive repair will fix?.    Or offline data-scan need to be done
