Array degraded with spare

[knowles13088]

I have a TS-563 with 5 hard drives installed. Drive are configured in RAID 5 array, with Disk 1 set as spare. Disks 4 and 5 have failed. DIsks 1,2,3 are still showing good, but the spare is not coming online to rebuild the array. Array is showing as read only.

I don't see where the setting is to bring Disk 1 into the array and start a rebuild.

Current firmware is 4.3.3.0154 (2017/04/13)

Where do I go from here?

Thank you.

If you have two failed disks in a RAID 5 array there is no way to recover it.

It seems coincidental with 2 drives failing simultaneously. Using enterprise rated drives (Seagate ST2000NM033). Spare did not have time to come online/rebuild.

Open a ticket with QNAP to see if they can diagnose what happened and if they can recover your array.

Update.
As the QNAP only contains system backups, I decided that I could be aggressive in dealing with the situation. I rebooted the NAS. All drives showing as good and the array is rebuilding.
I'm going to locate a readable file and see how usable it may be. Initial peek into some of the folders appear promising.
I'm going to let the rebuild complete and then do some investigating.

New update:
It appears the TS-563 failed two drives in the array within moments of each other. The drives are Seagate enterprise class drives, so not a slouch approach.
Running the long (SMART) tests on the failed drives still indicated failures. Added two new drives to the system. Long tests on the 3 good original and new are so far showing good.

Other forum topics are causing concern:

I'm leery of accepting two near simultaneous drive failures.

I have a working ticket with QNAP supoprt and awaiting their input

doesn't matter if enterprise or not, even they too have MBTF. what are their condition, are they brand new? or are they old and heavily used? are they still under warranty? when you bought them were they factory sealed or 2nd hand (which i never recommend ).

Drives are/were new in March last year, so I am sure under warranty. Heavily used? Not unreasonably so. We use it to do image backups from three small-ish servers nightly, and to store some archived information. I know drives fail, no matter what one might expect (been in IT for decades )
I'm retrieving the subject drives tomorrow for further evaluation. My frustration is with the loss of the array (and its archived data) in what I still think is a suspect series of events.

well not charles xavier, i don't know your background thats why i asked anyway but good to know.

ok so rougly a year old enterprise drive and 2 failing at same time. okay thats sounds rather dodgy i'd be skeptical too.

guess checking if it's a false positive on qnap side makes sense. but only technical support can really help you with that assessment

We are sorry to hear you're running into trouble here. Since you mentioned the drives may be under warranty and you've got an ongoing situation via the QNAP ticket, we just wanted to make sure you know that you can go to our Warranty Validation tool if you decide to look into doing an RMA on the drives down the road, and that you can get in touch directly with Seagate Customer Support if needed.
