No Volume Exists - Remove inactive volumes in order to use the disk
Hi,
Running v6.9.3
After a reboot the NAS came up saying "No Volume Exists".
Have done another couple of shutdowns and startups and it's now saying "Remove inactive volumes to use the disk....

2. Get output of current disk stats by running command:
# get_disk_infoYou can also get the disk stats from the logs if you like: disk_info.log
There's some additional information if you run
# smartctl -x /dev/sdX
using the actual disk (/dev/sda, etc).
In particular there is an error log for disk commands. I've been seeing some issues with one of my disks - volume reads sometimes time out (for instance, media playback freezes). Nothing shows up in disk_info.log. But when I use smartctl -x I am seeing stuff like this:

Though I'd expected that a UNC would either increase the reallocated or pending sector count, that doesn't seem to be happening on this particular disk. FWIW, kernel.log shows something like this when these errors occur:

So the lesson here is that disk issues might not show up in the SMART stats.
FWIW, I will be replacing the disk shortly (as soon as I finish testing the replacement). Then I'll test it more extensively with Lifeguard.

As for balance and defrag. I think a schedule of monthly defrag and balance is fine. I would also recommend doing a disk health check every quarter. A scrub is enough to do every 6 months or so. If your disk health is good and the initial scrub completes fine then you should be good to run scheduled tasks going forward.
There's no one right answer on this. Personally I do each test once a quarter. Though if a lot of files are changing on your NAS, then I think it does make sense to increase the frequency of balance. Defrag with btrfs is a mixed blessing - while reducing fragmentation will increase transfer speed on the the main shares, it also increases the amount of space used for snapshots. So there is a tradeoff there that you should be mindful of.
FWIW, The scrub also functions as a disk test, since every sector in the data volume is read as part of the test.
Disk tests passed fine, only incremented the power-on-hours and the disk stats now has a self-test Extended offline Completed without error.

Well, there was this error on sda (perhaps related to the ATA error)
Error 1 [0] occurred at disk power-on lifetime: 40806 hours (1700 days + 6 hours) When the command that caused the error occurred, the device was active or idle. After command completion occurred, registers were: ER -- ST COUNT LBA_48 LH LM LL DV DC -- -- -- == -- == == == -- -- -- -- -- 10 -- 51 03 b8 00 00 33 d8 ea c0 40 00 Error: IDNF at LBA = 0x33d8eac0 = 869853888
But it occured quite a while ago, so I wouldn't be concerned about it.

Just to follow up on my own smartctl -x issue...
That disk failed Lifeguard's extended test (too many bad sectors), It had 35 days of warranty left, so I started the RMA today.
