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.
