ReadyNAS Pro Stuck at Booting…
I’m trying to resurrect my ReadyNAS Pro and it’s stuck at Booting… It will complete the FS checks, but can’t get past Booting…. I’ve attempted an OS Reinstall and a USB Recovery, but the USB ...
Not sure this helps, but I had a similar situation many years ago. I apologize if my recollection of some of the details are a bit fuzzy.
My ReadyNAS (RAIDiator 4. something or other I suspect) declared a drive unusable due to unrecoverable read errors. Many many sectors were lost.
While hot swapping a replacement, another drive got jiggled sufficiently that it lost communication and the system said the RAID was gone. For reasons I can't recall, reinserting the good but disconnected drive did not appease the ReadyNAS and the RAID remained unusable.
The failing drive could not be copied due to unrecoverable read errors. As a hail Mary, I cloned the drive using the (somewhat infamous) Linux dd command. The trick was you can tell dd how many retry attempts to make when a sector can't be read. I told it to retry as many as 1000 time and if that failed, to write zeros into the definitively lost sector.
Cloning with dd this way recovered most, but not all of the lost sectors. When it finished cloning, I prayed a little, installed the clone drive, and booted the ReadyNAS. Miraculously this worked.
After that, I always used RAID6.

Better to have a backup strategy, as no RAID mode is enough to keep your data safe.

Cloning the drive can help (and often is recommended before trying to recover data, since the recovery process can stress the a failing drive more than cloning it).
It’s a hard lesson to learn and hopefully I’ll be able to clone my way out of my problem this time, but going forward, cold offsite backups will be used.
