I am having a weird problem where my 14tb WD disk (WDC_WD140EDFZ-11A0VA0_9KH23VWL in the diagnostics) will become unmountable while the array is up. I have had it happen a couple of times, and each time stopping the array, starting the array in maintenance mode, then running:
xfs_repair -L -v
on the drive fixes the problem for a while, before it then happens again. I had thought it was a bad SATA cable (had the problem every day or so), so replaced that and I had assumed that had fixed it as the problem went away for a few weeks, but it has started happening again over this week.
I have run extended SMART test, and getting no errors. The warranty for the drive runs out in Jan, so trying to work out if it is a drive problem, or if something else I am running is causing it.
I have run the above command and moved all data off the drive since the last time it did it, just incase there is a drive problem (I also know that I should be running a parity drive, but I set it up without one during testing and never got round to installing one - may repurpose this drive if it isn't on its way out).
Any help would be appreciated!
