Hi,
sorry for my bad wording, i have no crash with btrfs, I'm considering to=20
switch to btrfs on ssd disk comming back from warranty claim.
I was just asking, whether it's posible to switch my old setup (i described=
 in=20
my first mail) using mdraid to using btrfs internal raid without using mdra=
id,=20
ie whether it's possible to resync changed data on iscsi disk when i come t=
o=20
work in morning.

With regards
Libor

PS. If this mailing list is for bug/patches reporting only, then i'm sorry =
for=20
making unvanted mail traffic.
