Readynas Disappeared from network
Hi All, I set up my readynas in 2018 and it's been working fine since. Today I tried to access my files, and it wouldn't load. I tried to go to the IP address and it says not found. I checked my...
Since RAIDar found it diskless, then something has happened to the disks.
You can try booting up in read-only mode from the boot menu without disk 1 (but with the others), and see if that works.
If it does: the volume will be degraded (meaning no RAID redundancy). Offload your data before proceeding further, since it is at risk.
If it doesn't work: you can power down the NAS, and try again without disk 2 (but with disk 1). Similarly with disk 3 and disk 4.

The OS partition that the NAS boots from is RAID-1 (mirrored on all drives in the system). Normally the boot loader will boot from the first bootable disk it finds in the system - it doesn't fail over to the another drive if that disk fails to boot, and it doesn't take advantage of the RAID redundancy.
If the system fails to boot with disk 1 installed, but boots without it, then that generally points to a bad drive, and not a failed update. In that situation, I'd personally look at the log zip fip file for errors, and would also test the drive in a PC with vendor tools before reinstalling the drive.
Putting back in the original Drive 1 was probably not your best move, since it likely has errors and new problems could have arisen during the re-sync, but I'm glad it worked out for you.
