RN104 degraded, but no prorgess
Hi all. I am using my RN104 as a backup device sonce a very, very long time w/o any issues... Cool thing, not high performance, but good it works :-). I changed in my RN104 one of the 4 harddriv...
I agree it doesn't look like it's expanding. First, make sure a 4th partition was created: fdisk -l /dev/sdd. You can also compare the size of the 4th partition to another drive's: fdisk -l /dev/sdc. If the partition is there and the right size, then the following should add it or give you an error message as to why it won't: mdadm /dev/md127 --add /dev/sdd4 --verbose.
If the partition isn't there, don't try to use fdisk to create it, it'll refuse to start it in the right place. I recommend you install and use parted for that.
Hi Stephan.
Thanks for your reply.
1. "SMR-Drives"--- I have them since almost 2 years now and yes, I am in the progress of replacing them step-by-step - the one I replaced was also an "SMR".
2. Is resync really running? Usually I see it in the /proc/mdstat. Any proposal where I can see if resync is running if it is not shown on the readynas itself, the web-interface or in the /proc/mdstat file?

That's a good question. Usually it is shown on the volume page. Your mdstat post shows sdd is missing from md127 (but it is in the md126 raid group).
What drive did you recently replace?
I replaced 1x WD60EFAX with 1x WD80EFBX...
And yes, I know the difference between md126 and m127...Any idea?

So that should be sda.

The puzzle is why sdd is missing from md127. Replacing sda worked, so it must have dropped out after the resync the WD80EFBX completed.
Have you tried rebooting the NAS?
Hi Stephan,
Thanks for your effort.
The newly added WD80EFBX is sdd - all other drives show 5.5 TiB:
fdisk -l /dev/sdd
Disk /dev/sdd: 7.3 TiB, 8001563222016 bytes, 15628053168 sectors
And a reboot has not fixed anything before. I followed the manual approach as posted and in a couple of days I will see if this was the magic trick.
