If the failed disk is used in a RAID level 1, 5, or X-RAID volume, please note that volume is now unprotected, and an additional disk failure may render that volume dead. It is recommended that you replace the failed disk as soon as possible to maintain optimal protection of your volume.
How can I ensure if this disk is really failed? Before this year I never had any hard drive issues. (Unfortunatelly I have two Hitachi Touro Desktop as well, and after one month of use of of them crashed - 2T drives). Now I have issue with Seagate 3T drives (two in my duo v2). Is this high capacity drives not as reliable as hard drive were is past? hmm.
So Please advise me how to perform some tests before complaining to Seagate.
I have removed failed disk from bay. The indicator led is flashing. Does it mean anything?
Attach to data is a bit pain as having iMac and laptops. I may need some data-usb cable. No way to check from NAS? (I have this duo v2, and an old duo v1. V1 has root access, any linux tools to check?)
On both the v1 and the v2 via SSH you can use the smartctl command (google for MAN page) to check the SMART stats on a drive. On the Duo v1 with 2 drives installed the drives are /dev/hdc and /dev/hde. On the Duo v2 with two drives installed the drives are /dev/sda and /dev/sdb.
Of course if you like you could open a support case (please post case number preferably editing the thread title - that is the subject of the first post in the thread - to include it) and seek their assistance for confirming why the disk is considered dead. . If you look at the status log (Dashboard > Configure > System > Info > Logs) do you see any reports of errors on the disk?
If you download the logs zip file (Dashboard > Configure > System > Info > Logs > Download logs), extract the zip contents there are disk_smart logs which may also indicate problems with the disk.
not yet unfortunately. Just turn on back today with a single disk (what was reported earlier good, today this is the one having issues). My biggest problem now, unable to stop, turn off. On raidar a yellow box as status. Should I unplug? Pressed power btn for 20 secs, but nothing happened.
disks have been replaced by seagate, and it seemed to be fixed. But this afternoon again received a Smart error:
Detected increasing command timeouts[65537] on disk 2 [ST3000DM001-9YN166, W1F064BP]. This often indicates an impending failure. Please be prepared to replace this disk to maintain data redundancy.
