NAS540 RAID1 to RAID5 migration incomplete
I have a NAS540 device and it was configured in RAID1 on 2 4TB drives. after adding the 4TB drive I started migrating to RAID5. after reaching 100% (and it took 2 days) and after the next 24 hours, the spinning circle is still shown and the process has an incomplete status. On the Hard Disk tab, three disks are described as forming a RAID5 array. What to do now ?

Login over ssh, and execute
cat /proc/mdstat
to see what the kernel thinks about the conversion. I think the firmware daemon just missed the 'operation completed' signal.

Before restarting, I logged in to the console via SSH and checked the matrix status:
Everything seemed to be OK

After the restart, however, the system performed some other operations and after over an hour the system recovered and is in the RAID5 configuration. Nevertheless, thanks for your reply
