GUI item
Description
Device
Displays the name of the RAID unit. This indicates whether it is used for log message data or for mailboxes, mail queues, and other email-related data. This is hard-coded and not configurable.
Unit
Displays the internal mount point of the RAID unit. This is hard-coded and not configurable.
Level
Displays the RAID level that indicates whether it is configured for optimal speed, failure tolerance, or both. For more information on RAID levels, see “About RAID levels”.
Resync Action
Displays the status of the RAID device.
• idle: The RAID is idle, with no data being written to or read from the RAID disks.
• dirty: Data is currently buffered, waiting to be written to disk.
• clean: No data is currently buffered, waiting to be written to the RAID unit.
• errors: Errors were detected on the RAID unit.
• no-errors: No errors were detected on the RAID unit.
• dirty no-errors: Data is currently buffered, waiting to be written to the RAID unit, and there are currently no detected RAID errors. For a FortiMail unit in active use, this is the expected setting.
• clean no-errors: No data is currently buffered, waiting to be written to the RAID unit, and there are currently no RAID errors. For a FortiMail unit with an unmounted array that is not in active use, this is the expected setting.
Resync Status
If the RAID unit is not synchronized and you have clicked Click here to check array to cause it to rebuild itself, such as after a hard disk is replaced in the RAID unit, a progress bar indicates rebuild progress.
The progress bar appears only when Click here to check array has been clicked and the status of the RAID is not clean no-errors.
Speed
Displays the average speed in kilobytes (KB) per second of the data transfer for the resynchronization. This is affected by the disk being in use during the resynchronization.
Apply

Part of Unit
Indicates the RAID unit to which the hard disk belongs, if any.
To be usable by the FortiMail unit, you must add the hard disk to a RAID unit.
Status
Indicates the hardware viability of the hard disk.
Size
Indicates the capacity of the hard disk, in gigabytes (GB).
Delete
(button)
Click to unmount a hard disk before swapping it.
After replacing the disk, add it to a RAID unit, then click Re-scan.
 
 
Back up data on the disk before beginning this procedure. Changing the device’s RAID level temporarily suspends all mail processing and erases all data on the hard disk. For more information on creating a backup, see “Backup and restore”.
2. In the Level column, click the row corresponding to the RAID device whose RAID level you want to change.
The Level field changes to a drop-down menu.
3. Select RAID level 0 or 1.
4. Click Apply.
