In some situations it may be neccessary to increase the amount of disk space allocated to a Messaging Gateway virtual machine to accomodate increased log or quarantine storage requirements. Prior to SMG 10.8.0 it was not possible to expand the SMG filesystem even though the underlying virtual disk had been expanded. This has been addressed with the 10.8.0 and later releases.
Release : 10.8.0
To expand the disk space availe able to SMG for virtual machines under VMWare, Hyper-V, and Linux KVM:
usage: grow-disk [ --resize | --status ]
Just perform the final resize of the filesystem
Will perform a reboot
Show the characteristics of the physical disk and partitions,
but make no changes
If no option is provided, the system will be rebooted, and the disk
partition table will be modified to increase the size of the /data
partition to the maximum space available.
