Hi!
I'm installing sheepdog-0.7.x, next:
# mkdir -p /mnt/sheep/{metadata,storage}
# for x in 0 1 2 3 4; do sheep -c local -j size=128M -p 700$x
/mnt/sheep/metadata/$x,/mnt/sheep/storage/$x; done
# dog cluster format -c 2
using backend plain store
# dog vdi create testowy 5G
# dog  vdi check testowy
PANIC: can't find next new idx
dog exits unexpectedly (Aborted).
dog() [0x4058da]
[...]

I'm getting SIGABRT on every try.
