I will need to perform a maintenance on one of storage servers that provides GFS2 volume to a three node pacemaker cluster. Same cluster has an addition of 2 GFS2 volumes as well. Would it be safe to run pacemaker resource disable on GFS2 resource which needs to be stopped due to maintenance, without risking other GFS2 volumes to be stopped or possibly cluster fenced? These are constraints: Ordering Constraints: start dlm-clone then start clvmd-clone (kind:Mandatory) start clvmd-clone then start gfs2-ISO-clone (kind:Mandatory) start clvmd-clone then start gfs2-shared-clone (kind:Mandatory) start clvmd-clone then start gfs2-qcow-clone (kind:Mandatory) Colocation Constraints: clvmd-clone with dlm-clone (score:INFINITY) gfs2-ISO-clone with clvmd-clone (score:INFINITY) gfs2-shared-clone with clvmd-clone (score:INFINITY) gfs2-qcow-clone with clvmd-clone (score:INFINITY) The volume i would like to stop is gfs2-qcow that is gfs2-qcow-clone. If i run pcs resource disable gfs2-qcow-clone will other GFS2 volumes die?
