data degraded, however resync completed
I was upgrading other devices drives and I swapped a good working drive in my ultra 4 (6.6.1), the volume resynced completed, however then it says degraded. All drive lights are green on the volu...
Sounds like removing disk 3 and readding it after a minute would be the way forward, yes.
It's weird that it failed to rotate the journal when there is so much free space on the 4GB root volume.
well i found the answer to the scrub, there is an X on the progress bar that will stop the scrub.
i was also able to download the logs and I'm looking through them to see if anything stands out
I got ~2k lines of this;
[Tue Jan 10 19:06:06 2017] systemd-journald[1349]: Failed to write entry (19 items, 549 bytes), ignoring: Input/output error [Tue Jan 10 19:06:06 2017] systemd-journald[1349]: Failed to rotate /var/log/journal/f1dc4eef9ce14c55ad1d8a43499867d2/system.journal: No space left on device
which doesn't look good
Physical disk 3 is the one I had swapped, both disks are good, I just swapped a seagate 4tb to a hitachi 4tb, all disks are now hitachi 4tb.

It's weird that it failed to rotate the journal when there is so much free space on the 4GB root volume.Ok giving it a shot, thanks for the confirmation.
While browsing the various logs, I saw a few different errors related to disk full or to that effect.
edit: ok it's resyncing again. Hopefully it will finish cleanly this time.
thank you again!
