How to do it...
Perform these steps on any Pacemaker node as the root user:
- Export our list of XFS mount options to avoid long lines by executing these commands:
export OPS=noatime,nodiratime,logbufs=8,logbsize=256k export OPS=$OPS,attr2,allocsize=1m
- Add an XFS primitive to Pacemaker with crm:
crm configure primitive pg_fs ocf:heartbeat:Filesystem \
params device="/dev/VG_POSTGRES/LV_DATA" \
directory="/db" \
fstype="xfs" \
options="$OPS" \
op start interval="0" timeout="60" \
op stop interval="0" timeout="120"
- Clean up any errors that might have accumulated with crm:
crm resource cleanup pg_fs
- Display the status of our new XFS resource with crm:
crm resource status
