Warning Cache pool BTRFS missing device - But disk appears to be online?

Featured Replies

Hey,

 

I have a quick question, when I started up my array I got a warning:

 

unraidserver: Warning [UNRAIDSERVER] - Cache pool BTRFS missing device(s)
KINGSTON_SH103S3480G_50026B724B05B2DE (sdi)

 

But when I look at the Cache pool, it looks fine:

And the output of "btrfs fi show" is:

 

Label: none  uuid: 0130b325-8ce1-4ceb-a715-467c12ccc4eb
        Total devices 4 FS bytes used 252.93GiB

        devid    7 size 447.12GiB used 148.00GiB path /dev/mapper/sdi1

        Total devices 1 FS bytes used 8.12GiB
        devid    1 size 50.00GiB used 11.52GiB path /dev/loop2

Should I be worried? I can't restart the server atm because it is doing a rebuild and parity check

The server did restart like 4 to 5 times because I was diagnosing multiple disks being offline (and it is fine now)

 

Also it gives me a warning on the shares pages: "Some or all files are unprotected" even the shares without cache drive, or is this because of the rebuild? Don't remember seeing it before..

But finally I wonder, too, why this isn't visible in the GUI and only a notification comes up?!

 

Depending on the issue there might not even be a notification, I suggest using a script to monitor any pool.

No feature request to implement this directly into Unraid?
