Thanks for the comments.
Sorry for the delay.
Trying to find out if there is any pending concerns...
Hopefully, per-filesystem hot-spares will be a high priority too, as
that type of usage is pretty much required for many enterprise type
uses, although that doesn't need to be the same code

Aside from what Duncan said (and I happen to agree with him), there is
also the fact that hot-spares are (at least traditionally in most RAID

Thanks for the comments.
Let's take the following example:
1) 2 RAID1 + 1 spare
(A + B) + C
2) 3 RAID1
(A + B + C)
At least in normal operation case, case 1) makes device C useless, and
Yes.
For case 2), we can just relocate and recover the bad chunks in B.
It it should only

Hi Anand,
is there any reason to put this kind of logic in the kernel space ?

It's absolutely awesome to see that someone picked up this project, it's
something that's very useful and helps BTRFS to compete with many
