Hello,
today I wanted to remove one drive from raid1, and people at #btrfs advised me
to use '-dconvert=single' before 'btrfs device delete'.
I thought of adding '-mconvert=dup' too, but the kernel does not let me do that.
It looks like 'dup' is disallowed for an array of multiple devices. So, to go
back to a single-drive (single/dup) setup, should I go through having the
metadata with 'single' profile?
I can't use 'btrfs device delete' either, because that wouldn't respesct the
raid1 profile.
Maybe then the easiest I could do is to use the computer degraded, until I get
some new disk in some days? That'd be equivalent to metadata=single, as I
understand.
And having a totally new disk, having removed the broken one, I'd have to:
1) mount degraded
2) btrfs device delete the missing disk (will I be allowed? due to raid1 profile)
3) btrfs device add another disk
Should that work?
Regards,
Lluís.
