NAS/RAID problem

    Hello all,
    I have a problem with my NAS and I need to clarify if one of the disc went bad or the unit itself.

    Suddently one time I could connect to NAS over the network. It was pinging but no web interface, so ssh (Ihave the Jac2b firmware installed btw). When I went to physically see the unit I saw the power and hdd's leds flashing. I pulled the plug and put it back. The unit powered up a bit slowly. After the double beep I accessed the web interface and saw in Volume Status: Rebuilding Disc 1 from Disk 2. I let it finish -like 30 hours- and after it finished I initiated a scandisk remotely and found out afterwards that the leds were flashing again and had no access to the unit.
    After restarting the unit it was rebuild once more from Disc 2 to Disk 1.

    What do you recon? In case it is the HDD and I replace it with another brand same capacity (I have Seagate 1TB disks) will it have complications in rebuilding Disk 2 to new Disk 1 ?

    When the lights are flashing that way, it means the unit is checking the disks and/or rebuilding the mirror. If you switch it off, it will have to start over.

    If it keeps rebuilding disk 1 it probably means the one that's in there is unreliable. You can replace it with another disk and the NAS will rebuild the mirror with the new disk automatically (although it's possible that you have to do a format from the web interface first but I kinda doubt it).

    Note, the NAS200 doesn't support hot swapping, so turn it off with the power button (and wait for the lights to go out) before you change the disk.

    OK I have to check that disk to see. But what I have noticed is that when rebuilding, the LED pattern is flash first HDD1 then HDD2 and PWR steady. When I cannot login to the unit all three LEDs flash simultaneously approximately every second. I dont know what that pattern means.

    Check the manual of the NAS200. There you will find the red flashing patterns and their meaning.

    One disc went bad and caused the whole thing. The power company had a failure and the whole neighborhood was out of electricity for a couple of hours. The UPS couldn't last that much and the disc failed...

    Sheez, we've had some pretty bad power outages here recently, and because i don't own an UPS, the whole PC went down hard a few times. But no HDD failure. To me, it seems odd that you HDD failed catastrophically after one lousy power outage.
