Enable rsync/ssh/frontview from tech support mode on ReadyNAS NV+?

[tinymonkey1]

My ReadyNAS NV+ went into storage, and came out copletely locked down.  It doesn't respond to http, https, ssh, rsync, and doesn't show up as any kind of network share.  I've tried booting via USB, and in the 5 I tried, I found a stick that actually worked.  Still nothing shared.  Did the OS reinstall, and got it to bind to a different IP address, so something changed.  But still nothing shared.  After repeating that, now it hangs during "Booting..."

I am able to boot into tech support mode and telnet in.  Now I just need to know what to do,,,  Can I enable a service somehow?  Where are the config files?  Do I need to mount something first?  Is it possible I could start rsyncd in tech support mode?

Thank you!

If sounds like you need to extract data from the NAS - is that correct?

Also, what firmware is your NAS running?  Do you recall if you were running XRAID or FlexRAID?

That's right, I'd like to get my data off of the NAS however I can manage.  I'd settle for something hacky.  It's running RAIDiator-4.1.16, and yes, XRAID I believe.

Assuming XRAID - once you are in tech support mode, you mount the OS partiton and chroot in

# start_raid.sh

# mount /dev/hdc1 /sysroot

# mount --bind /proc /sysroot/proc
# mount --bind /dev /sysroot/dev
# mount --bind /dev/pts /sysroot/dev/pts

# chroot /sysroot /bin/bash

If you were using flexraid, then the first mount would be /dev/md0 instead of /dev/hdc1.  Everything else is the same.

You can then attempt to mount the data volume (best to do this read-only)

# vgscan
# vgchange -a y

# mount -o ro /dev/c/c /c

If that all works, you can mount a USB drive, or try to use rsync to offload your data.

Of course if the RAID isn't in a good state, the commands will fail at some point.  If that happens, I suggest going to RAID recovery, and not attempting to fix it by hand.  If you can connect your disks to a PC (either SATA or USB dock), then R-Studio might be worth a look. https://www.r-studio.com/  Netgear also offers a data recovery service: https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service

Thank you so much!  I had figured out the first few steps, but the rest would have taken me quite a lot of time.  You just saved me a lot of pain and suffering!
