All of its partitions were recognized, but the big partitions with the relevant data were listed as being of an "unknown" type. So I initialized the NAS on an SSD drive I had, and hooked the RAID1 drive up again. Inserted cloned drive, and got a message saying a drive with a QNAP signature was detected, but a factory reset was required. As I was shucking the surviving drive from its plastic cradle, I noticed one of the screws securing it was missing. (C) Are hardware failures as described above (except the external HDD, which was probably misconfigured) a regular occurrence, and is there a subsequent NAS purchase I could make to mitigate those risks? Yes, I know that all of this wouldn't be a problem at all if the external HDD had been properly configured.Įdit: And I -think- I've figured out why the system failed. (B) If mounting in Linux is not possible, what other solutions exist? (A) Can a single drive from a QNAP RAID1 created with the default firmware that comes with a TS-251+ be recovered with Linux? So, if anyone here could help me answer three questions, I'd surely appreciate it: However, at this point, I'd be happy to pay someone to fix this problem for me. (8) The people that own this thing have not properly budgeted for catastrophic data recovery. (7) MDADM cannot automatically mount raid arrays created by QNAP, apparently? It creates an MD for each RAID1 partition, but you cannot actually mount those. I'm cloning with DD because I have no idea what I'm doing and am properly terrified. (6) My MDADM-fu is basically limited to setting up new raid arrays and having it 'just work'. Its about 4TB, so it will be a little while. (5) Currently cloning the storage portion of the intact drive to a disk of identical size with DD. It refused to be recognized on multiple SATA ports with known good cables. (4) Connecting the drives via SATA to an independent machine revealed that one of the RAID1 drives was dead as a doornail. (3) The external hard drive which was serving as backup was either misconfigured or caught up in the same event.
(2) The firmware is reported as being whatever comes with the TS-251+.
Anyway, one drive in the RAID1 array is dead, and the TS-251+ refuses to power on further. (1) During a routine power-off to relocate the NAS, something happened. Getting roped in to a bad situation, it seems.
