Ultra2 stops working after boot
Hello. My RNDU2220 works fine since.... a lot of years Last month, after a long global power outage (UPS out of battery), the NAS runs strangely. It hangs just after the boot. Here's a sample o...
What firmware was the system running?
Do you have a backup for the files on the NAS?
I don't really remember... 4.2.26 or 4.2.29.
I tried to "reinstall the OS" via the boot menu, but nothing happen.
And I don't plan to lose data.
The NAS says it is shutting down, but you are still getting information via ssh?
Does that mean that the NAS is still running, but that the shares (and frontview) are not available?
If so, is the data volume still mounted?
- I just have the time to connect during the boot through a SSH connection (with private key), and to copy (with scp command) some log files.
The volumes seems to be mounted. All the shares are available.

You could boot up the NAS in tech support mode and then get to the linux command line with telnet. From there you can mount the OS partition and the data volume manually, and then back up the files to USB disks.
Not sure if you can block the firmware update process, it depends on what is triggering it. You could look for /.cf_update_in_progress, and delete it if you find it. Similarly for /.os_update
If those aren't there (or if deleting them doesn't help), then you'd need to do a factory default (and maybe a USB recovery).
Have you ever used tech support mode?
