RNAS-1200 Series Enabling Fast Synchronizations for RAID 1
10-2
Enabling Fast Synchronizations
The RNAS-1200 features Fast Synchronizations for its RAID 1 architecture. While this comes at a small cost
to regular access times, when this feature is enabled the file system will store the position of the last successful
write and, in the event of unexpected system crashes, begin resynchronization of the drives from that position.
This means that unexpected system crashes will no longer cripple your RAID with laborious, hours-long
resynchronization processes. When data inconsistencies occur, fast synchronizations will be able to
synchronize a two disk array in only seconds, or two or three short minutes at the very most. Please note that
fast synchronizations are only meaningful in RAID 1 architectures.
ATTENTION
To enable fast synchronizations, you must toggle the
Fast Synchronization box when you are configuring
your RAID 1 array.
