BTRFS drive is readonly

[bar1]

Hi, having a lot of issues here with my 8TB drive.

I currently removed it from the array and trying to troubleshoot it as a mounted drive.

 

Drive only mounts as read only and if i try get files off it i often get an error.

i can start a btrfs scrub (with or without -r)

but when i check:

Status:           aborted
Duration:         0:00:00
Total to scrub:   5.85TiB
Rate:             0.00B/s
Error summary:    no errors found

 

btrfs check --repair /dev/sdd1
enabling repair mode
WARNING:

        Do not use --repair unless you are advised to do so by a developer
        or an experienced user, and then only after having accepted that no
        fsck can successfully repair all types of filesystem corruption. Eg.
        some software or hardware bugs can fatally damage a volume.
        The operation will start in 10 seconds.
        Use Ctrl-C to stop it.

Opening filesystem to check...
ERROR: cannot open device '/dev/sdd1': Device or resource busy
ERROR: cannot open file system

 

....anything else i can do to recover files from the drive before format?

most of the stuff on the drive is backed up anyways, so not a big deal

I attached the SMART log....drive should still be under warrenty

See here for some recovery options.

But there might be a serious issue with the drive, in that case you can also try ddrescue first.
