RAID Recovery is a QNAP exclusive and unique feature for RAID data protection during accidental disk removal or SATA connector failure.
http://docs.qnap.com/nas/en/index.html? ... gement.htm
"When the NAS is configured as RAID 5 (or RAID 6, 10) and any number of hard drives is uplugged from the server accidentally, you can plug in the same hard drives into the same drive slots and click ‘Recover’ to recover the volume status from ‘Not active’ to ‘Degraded mode’."
RAID from other competitors will crash and cause data loss if you unplug more than the allowed disk numbers in RAID.
RAID Recovery is available for QNAP NAS models with HDD hot-swap function.
TS-212 can still perform RAID rebuild if 1 HDD failed in the RAID 1 setup. You just nee to turn off TS-212, and then replace the failed HDD, and then power on the NAS for automatic RAID rebuild.
RAID recovery, as described by QnapJason, is only applicable when using RAID 5, 6 or 10 so not an option on any two-disk unit.bosk wrote:After a long search I found an entry in the QNAP FAQ. As the TS-210 is very similar to the TS-212 this NAS does NOT support any RAID recovery!
The lack of Online RAID Migration feature is a limitation of the low-end models TS-210/212 that is clearly communicated in the marketing material. That feature is not the same as recovery of a degraded RAID 1. The latter is supported on all models that have RAID 1.How can I migrate from Single Disk to RAID 0/1 in TS-210?
