yes, xfs does; we have "-o norecovery" if you don't want that, or need

That option also works with Ext3/4 so it seems to be a standard way of
dealing
with this. I think that BTRFS should do what Ext3/4 and XFS do in this
regard.
BTW, does -o norecovery implies -o ro?
If not, how does it keep the filesystem consistent?
I'd like to follow that ext2/xfs behavior, but I'm not familiar with
those filesystems.
Thanks,

OK, norecovery implies ro.
So I think it's possible to do the same thing for btrfs.
I'll try to do it soon.
Thanks,
Qu
