LaCie RAID Manager can help you maintain optimal performance on a virtual disk using Consistency check and Consistency fix.
A consistency check scans and reports the integrity of parity or mirrored data on the virtual disk. Periodic consistency checks are highly recommended as part of regular maintenance for virtual disks. Users should also run a consistency check when a virtual disk is not performing as expected.
A consistency fix scans, reports, and fixes parity or mirrored data on the virtual disk. You can choose to run the consistency fix instead of the consistency check if you suspect that your virtual disk is experiencing problems. A consistency fix can take longer to run than a consistency check.
As described in Create Arrays and Virtual Disks, LaCie RAID Manager runs an initialization on a virtual disk when it is first created. Similar to a consistency fix, the initialization scans the virtual disk’s hard drives for errors and performs repairs if necessary. There are two types of initialization:
The option to run a consistency check/fix is available only after a full initialization has been performed on a virtual disk.
A full initialization can be run as one of the following:
Follow the instructions below to run a consistency check/fix:
The consistency check/fix will take many hours to several days based upon the total capacity of the virtual disk. You can continue to use the hard drives but performance can be affected by the consistency check/fix.
LaCie RAID Manager gives you the option to schedule regular consistency checks/fixes and background initializations. Regular maintenance on the hard drives can help to prevent data errors and improve the health of the virtual disk.
Consistency checks/fixes and initializations can be scheduled:
