Ok, thank you.



I insert back node 2 then I run the second test:
unplug of /mnt/sheep/dsk01 on node id 2.
Note: I also run 'cluster reweight' without waiting the recovery to be done.

On node id 2 I get lots of

Is this right?

On node id 1 I get a single
Jun 25 11:22:59 [rw] sheep_exec_req(548) failed No object found

(Note: guest is always running and writing 1M of data each 3 seconds.
No error reported on guest side).



PS: by mistake I run vdi check while guest was (and is) still running.
I noticed this message on node id 0 (it's the node where the guest is
running on)
