Hot-Spare Rebuild in Transparent RAID

Warning

Although the idea of global hot-spare rebuild is charming, one should not discount the value of human interaction and decision making when it comes to data restoration.
In fact, using this automatic restore feature is NOT recommended.
Instead, you are advised to manually inspect the defective drive first, backup the array if possible, and then attempt the restore process.

Global Hot-Spare

Hot-Spares are global in Transparent RAID. Any unused registered disk is an automatic candidate to be used as hot-spare.

When a disk fails, and if the array it is in is configured for automatic rebuild on failure, the system will scan for the most appropriate free registered disk and use it as replacement disk for the failed disk.
