Not sure myself.
Can you download the log zip file, and post mdstat.log and mdconfig.log?
Had to covert files to PDF. Looking at this file, it is obvious that the RNP thinks I only have 4 working disks yet Frontview shows different.
You can just copy/paste text snippets from the logs.
mdstat shows the system is somewhat confused.
- md1 and md4 are using all disks (including the missing/dead one)
- md0 and md3 are using the missing/dead disk, but not the new one
- Only md2 is correct.
This could probably fixed with ssh (or by paid support). Another approach is just do a factory reset, and restore the NAS from backup.
Hi Stephen,
I am happy to try fixing with SSH. If that fails I can always do a factory reset but it will take a long time to resore everything due to only having USB2 speeds.
Can you tell me what I should modify?
File "/proc/mdstat" is a zero length file but when I type "cat mdstat" it shows what is in the log file. And if I try "vi mdstat", i get a new file.
Thanks,
Andy.

It's quite a bit faster to connect the USB drive to a PC and transfer over the network.

You'd need to run mdadm to add drive 5 to the RAID groups that are missing it, and then remove drive 1 one from the RAID groups that still have it.. I'm not certain of exactly what the commands would be. Sandshark probably has a better idea, since he has recently been playing with mdadm on OS-6.
