Hi,
sorry for my bad wording, i have no crash with btrfs, I'm considering to
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
my first mail) using mdraid to using btrfs internal raid without using mdraid,

adds ioctls necessary to start and cancel scrubs, to get current
progress and to get info about devices to be scrubbed.
Note that the scrub is done per-device and that the ioctl only
returns after the scrub for this devices is finished or has been
canceled.

each chunk, the contained extents are enumerated and the data checksums
fetched. The extents

- during a log commit, scrubbing of supers is disabled
- on unmount, the scrub gets cancelled
- on device removal, the scrub for the pa

iscsi lun was set writemostly.
So when i came to work, i fired up iscsi, added lun to raid and partial resync
went ahead.
