Raid1 resync
Hi,
before my ssd crashed, my /home partion was sitting on md raid1 consisting of partition on disk and iScsi LUN in network, it was created with bitmaps and iscsi lun was set writemostly.
So when i came to work, i fired up iscsi, added lun to raid and partial resync went ahead.
Before leaving work, i failed iscsci disk and kicked it from raid. I would like to use something like this with btrfs, without mdraid below it.
Is it somehow posible?
1) I can't go below 2 devices.
2) Does btrfs support resync only of changed blocks like mdraid with bitmaps?
Thanks
Libor
Hi Libor:
Maybe, you can attach your oops at first.

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, ie whether it's possible to resync changed data on iscsi disk when i come to work in morning.
With regards
Libor
