Growing Metadevices

To grow a metadevice, you must have a least two slices (disks) in different multihost disk expansion units available. Each of the two new slices should be added to a different submirror with the metainit(1M) command. You then use the growfs(1M) command to grow the file system.

When the growfs(1M) command is running, clients might experience interruptions of service.

If a takeover occurs while the file system is growing, the file system will not be grown. You must reissue the growfs(1M) command after the takeover completes.

The file system that contains /logicalhost/statmon cannot be grown. Because the statd(1M) program modifies this directory, it would be blocked for extended periods while the file system is growing. This would have unpredictable effects on the network file locking protocol. This is a problem only for configurations using Sun Cluster HA for NFS.
