How can I modify CFSMount resource options without having to offline the mount?
Configuring the mount options for a CFS Cluster can be done in two ways.
1. Using hares to modify the CFSMount resource by modifying the MountOpt attribute of the resource.
hares -modify MountOpt cluster,rw,convosync=direct,mincache=direct
-- Requires an offline and online of the resource for the mount option to take effect.
2. Using the mount command directly to update the mount options.
mount -F vxfs -o remount,cluster,rw,convosync=direct,mincache=direct /dev/vx/dsk// /
--- Your are still required to modify the resource MountOpt so that on the next reonline the correct mount options are used by VCS. Although the remount does not require downtime.
--- The remount would have to be done on each node in the cluster.
