I have a super simple home setup. 2x2TB drives, each its own static volume, with a nightly backup job.
The system volume is a bit iffy, SMART info shows it has 7 pending sectors (raw value), so it is mounted RO.
Say I'm OK with the risk, and would like to mount it RW. Like I wrote above, it's a simple home setup, I'm not afraid of data loss and willing to take the risk.
I have scanned for bad blocks, checked the file system and did the SMART quick test. Still, it is mounted RO.
What are my options? How can/should I convince QNAP to mount RW?

Re: DataVol1 (System) is read only
probably none at all(GUI)..swap the disk for a new one
Or you could wade through the md documentation and see if there is a way to force r/w
e.g.

Re: DataVol1 (System) is read only
thank you, dolbyman. Just to reiterate, I'm not using RAID at all.
Couldn't a simple remount do the trick? I'm just unsure what options I should use.
I've no problem using SSH. Although I haven't done that in a long while, I'm no stranger to linux or man pages.

Re: DataVol1 (System) is read only
Do you even know why the volume is read only? Is it because the system detected errors on the drive, or because the volume is full?
You can try to remount it read/write behind QTS' back. Don't know why you would want to do that or what good it will do, but whatever. If that's what you want, have at it, using SSH:
Have fun
* I don't know what the mount points for static volumes look like. Replace /share/CACHEDEV1_DATA with the actual mount point for your first volume as applicable.

Re: DataVol1 (System) is read only
It must be the bad sectors. The volume is most definitely not full, just about 90% full.
I was, wrongly, it seems, under the impression that mount/umount is the way to go since it's not a RAID. I'll do some reading about mdadm and Any more information you'd suggest I try to collect before attempting to do that?

Re: DataVol1 (System) is read only
Go to QuLog Center and look at the System Event Log. There should be some past message(s) there showing when the system put the volume in read-only mode and why.
