Ultra 6 Replacement Drive Not Syncing
I've been running a ReadyNAS Ultra 6 Plus (latest official firmware) for some six years (and an NV+ for years before that), so when I got messages that one of the six 2-TByte drives (Seagate ST2000DL...
Just came across this thread again and thought I'd give those who have been following these travails with rapt attention some closure: Six months later, the system runs fine under OS 6 without any more disk troubles.
Thanks. I knew that drives which already are partitioned may not be promptly recognized. It is for that reason that I deleted all partitions on the PC before returning it to the ReadyNAS. Also, if I interpret the sgdisk output correctly, ReadyNAS does not see any pre-existing partitions on the replacement drive (/dev/sdb) either.
For lack of any guidance, I zapped the partition table on the new drive (sgdisk -Z /dev/sdb) and rebooted. On boot, the front panel indicated "testing disk 2" for a few minutes, followed by "disk 2 passed" But I can see now indication that the sync is actually taking place. Is there any log/etc I can look at using ssh that would give me some clue about what, if anything, is happening. All the relevant lines from /var/log/syslog were in the original post.
There is an expansion log (expand_md.log in /var/log/frontview).
If you hover your mouse of the disk "ball" icons in frontview or RAIDar, you also get some status.
Thanks, StephenB. After the 'sgdisk -Z' and reboot, I think the expansion actually has started. The NAS emailed me "Data volume will be rebuilt with disk 2." The volume and disk balls in frontview are blinking yellow.
The expansion log follows. I *think* that means that expansion is proceeding, but only waiting 24 hours will tell.
