This script supports the following parameters for Windows & Linux platforms:
|
|
-d <deviceNames>, REQUIRED, Space separated list of devices to mount /data on,
|
|
i.e., "xvdb xvdc", more than one device indicates a RAID set.
|
|
For Windows, specify the drive letter, i.e., "d".
|
|
-r <raidDeviceName>, REQUIRED, if more the one device is specified in <deviceNames>,
|
|
i.e., md0.
|
|
Not supported on Windows.
|
|
-t <fsType>, File system type, defaults to '$fs_type'.
|
|
Not supported on Windows.
|
|
-o <mountOptions>, File system mount options, i.e., "-m crc=0,finobt=0".
|
|
Not supported on Windows.
|
