Hello!
my btrfs nvme drive won’t mount by default.
I am able to mount -o ro,rescue=all and am copying files to external HD.
any way to save the filesystem? or is this a reinstall?
Or should I get a new nvme?
Thanks.
mount: /var/mnt: can't read superblock on /dev/nvme0n1p3.
dmesg(1) may have more information after failed mount system call.

I tried a btrfs check:
sudo btrfs check /dev/nvme0n1p3

I think the nvme is ok:
do smartctl -x /dev/nvme0n1
