Is my Duo v1 dead?

I have a ReadyNAS Duo v1 with twin 1TB drives that has served me well until recently.

After a number of power cuts that affected the area where I live, I now have a NAS that won't boot properly.

It seems impossible to connect to its FrontView interface, and neither of my copies of RAIDar (one on Windows and
one on Linux) seem able to detect it. I only know it's there because I have given it a fixed IP address from my
router and I can ping it.

I've tried just about everything I can think of;
- booting with disk 1 removed
- booting with disk 2 removed
- OS re-install (quick reset press)
- Factory reset (long reset press)

None of these seem to have made any difference - the power LED sits blinking at a rate just over 1 per second

I know that at least disk 1 is good - I can see the files using the FUSE on Ubuntu procedure described elsewhere
in these forums, and although disk 2 does not show this, it is correctly identified in terms of manufacturer and
size etc by Linux. Disk 1 still shows the files AFTER the factory reset, which implies that that did not work?

The interesting thing is this. With both disks installed in the Duo, if I perform the "Tech Support Mode" boot
and login, there is only 1 log file in /var/log/frontview. It's called enclosure.log and contains this:

# cat enclosure.log
model!!0!!mode=home::descr=ReadyNAS Duo::arch=nsp
fan!!0!!status=ok::descr=3921RPM
disk!!1!!status=not_present
disk!!2!!status=not_present
#

If I repeat this boot, the RPM speed shanges slightly which implies that the log is being written to on boot (there
appears to be no timestamp on the file).

So .... it appears to me that the Duo is not seeing either disk. This explains why neither the factory reset or
OS re-install boot worked, and why the NAS itself won't boot. But, I know that disk 1 is perfect, and disk 2
is probably good (I may well try and restore to it outside of the Duo to prove this), so, to me, this implies that
my Duo is dead.

Perhaps (hopefully :)) someone will correct me? Is there anything else I can check or do?

    If you still see the files, then you are correct - the factory default didn't work.

    If you have all the files backed up, try deleting the partitions on drive 1 on a Windows PC, and power up the NAS with only [blank] drive 1 installed.

    What happens if you do

    # sh /bin/start_raid.sh

    ?

    If using X-RAID post the output of

    cat /proc/xraid/configuration

    If using Flex-RAID post the output of

    cat /proc/mdstat
  • Many thanks to both of you for replying.

    StephenB, I will try your suggestion over the weekend if I get a chance - I'd like to secure another backup before blowing up what at the moment is my only good copy with all the files in 1 place. I do have everything secure, but it would take a bit of effort to put it all back together.

    mdgm, as your suggestions only take a few seconds to run, here is what I found;

    # sh /bin/start_raid.sh
    # echo $?
    0
    #

    # cat /proc/xraid/configuration

    Now if I read that correctly, it's saying I have 2 drives (both "present"), 1 of which is faulty? Physical drive 0 (can I assume disk 1) is the faulty one? If this is correct - it doesn't make sense - disk 1 is the one I can read the files from through Ubuntu.

    My need to check disk 2 and copy everything to it outside of the Duo just increased!!
  • One other thing; why would the xraid config file suggest both disks are present when the enclosure.log suggests they are not?
  • Ok, so I've done a bit more digging. I can present disk 2 to my Linux box, partition the drive, create a filesystem across the whole device and then copy all of my files to it without error. I'm taking this as a perfectly working drive - unless someone can explain otherwise :)

    I've re-run some of mdgm's suggestions with disk 2 still removed from the Duo. The enclosure.log has been updated as the fan spin rate has changed again (by 300 RPM due to only 1 drive?), but this log is still claiming that I have no disks:

    # cat enclosure.log
    model!!0!!mode=home::descr=ReadyNAS Duo::arch=nsp
    fan!!0!!status=ok::descr=3614RPM
    disk!!1!!status=not_present
    disk!!2!!status=not_present
    #

    The xraid config file now has it that drive 2 is "faulty", but present :? and drive 1 is good:

    # cat /proc/xraid/configuration
    VERSION/ID::superblock=(0.1.0),ID=0e2087bf.00000000.00000000.00000000,create_time=516c5f19

    I'd really appreciate any comments on this. I feel that I need to either fix this or replace the unit - afterall, I don't have to repalce the disks!!

    That's not the way to detect a failing disk. Hook the drive up to an internal SATA port in your Linux box, boot off the Ultimate Boot CD and check the health of the disk using the manufacturer's tool e.g. SeaTools for SeaGate disks.

    Odd. The earlier post suggested disk 1 (0) not disk 2 (1) was faulty whilst your latest post in this threads suggests the opposite. Do you have an explanation for this?

    Tech support mode is a low level diagnostics mode. In this mode the disk status isn't necessarily accurately reported in the enclosure.log file.
