Readynas Pro 6 - Err Used disks Check RAIDar
I have a ReadyNAS Pro Pioneer edition with six 2TB disks running OS6 that now displays "ERR: Used disks Check RAIDar" when booting. This problem occurred recently when i swith it on after s...
If it were my system, I'd test the disks with vendor tools in a windows PC (seatools for seagate, lifeguard for western digital). Replace any that fail (or which have more than 50 reallocated+pending sectors).
Then do a factory reset with all disks in place. Reconfigure the NAS and restore the data from the backup.

as far as i understand 4gb roos FS internal flash is broken (my NAS have about 6 years uptime). is it true?
I don't think your flash is damaged - if it were, you'd likely have failed to boot into tech support mode. It's more likely that the OS partition on the disks is damaged (along with the data volume's file system). /dev/md0 is the OS partition on the disks.
You can test this by installing a scratch disk in the NAS by itself, and attempt to do a factory reset from the boot menu. If that works, then problem is with the disks, not the flash.

exactly! you are right.
what should I do further?
I do a backup, of course. and... and what's next? my disks have 4-6 years uptime... I have to buy new disks?
and why system corrupt so heavy? volume was RAID5. Upon failure of a single drive, subsequent reads can be calculated from the distributed parity such that no data is lost.
