RN314 problems after Readynas 6.10.7
After install of 6.10.7 (apparently trouble free) on a RN314 (4*6TD WD drves) that has been in use for years, the gui degrades to the point where no data appears in the admin page. In the short time...

One caution is that the error in the screen shot is a read error - normally if mdadm is rebuilding a disk, it is writing to it. So there still is some uncertainty on exactly what is going on.
sdb is normally the second disk from the left (the disk in the first slot normally is sda).
If you aren't certain, you can also get the serial number with smartctl -x /dev/sdb (along with a lot of other information). Then you could power down the NAS, check the disk serial, and boot up the NAS read-only without it. If the volume is there, but degraded, then you could reboot again normally. Then do a hot-insert of the replacement.

StephenB,
Thanks for this recommendation. I used journalctl -r and found many references to errors on sdb and sdb4 .
The only way I know to show others is with a screen shot so my output is in .png format. But this limits me to a single page.
So should I hot swap sdb (drive 2 as 1,2,3,4) or is it sbd (drive 2 as in 0,1,2,3) The output from mdstat infers drive numbers are 0,1,2,3
And are these numbers from left to right as looking from the front??
I am still seeing ~7.5% completion on the resync after 4ish days. So waiting for a completion may see me being a very old man.
If swapping sdb ends in failure, I guess my next step is to do the factory reset reboot?? Or is there a wiser way?
Regards, and thanks, Alf
