Re: Updated to 6.2.5. Started a rebalance, now nas dead

mgiammarco · ‎2015-08-24

Hello,

in the past I had several problems with my readynas 102: system was unstable expecially with nfs/array rebuild and so on.

Now I installed os 6.2.5 and things seemed to work better.

So I decided to start a rebalance because the nas tell me that my disks are almost full and it cannot be true.

The nas started a rebalance and at around 20% it started not responding.

Waited several hours then hard reset it.

This time the nas stopped at boot with power light flashing.

Following netgear guides I did an os reinstall.

Nas started working again but it did automatically continue rebalance operation.

Again a 35% it stopped responding.

This time reinstalling os did not work and now I have a stuck nas with power light flashing.

What can I do?

It is obvious it is again a software problem.

Thanks in advance for any help.

Mario

When it tells you your disk is almost full you should check for advice first before running a balance.

Before running a balance you should get volume usage down to the 80-85% range.

Do you have a backup?

I received the 80% full warning then 90% full warning. Then I checked and freed some space to came back to 80% warning.

So when I started the rebalance the volume was at 80%-85%.

I have backups but recreating and reimporting data in all virtual machines is a very time consuming process.

Anyway I could not understand how I can destroy the nas using an allowed operation from the gui. At least the system should boot. Is the boot partition on btrfs too?

Thanks again,

Mario

The OS runs in its own partition, on the RN102 that partition is formatted ext4.

So why it does not boot? I have reinstalled os several times. How can I debug it?

Sent you a PM.

I suspect it is stuck trying to mount the data volume. Was ssh enabled?

You can try the boot menu option for read-only (page 16 here: http://www.downloads.netgear.com/files/GDC/READYNAS-100/RN_OS_6_Desktop_HW_UM_26March2015.pdf)

Maybe also the disk tests.

I wouldn't try OS reinstall or factory default at this point. Someone from Netgear might want to try remote diagnosis.
