[ENBD] Problem when restarting enbd-client

[Anders Blomdell]

enbd-client server:30000 -n 2 -i 2_disk_a -m -t 0 -b 4096 -e /dev/ndb
mkfs.ext3 /dev/ndb
# Up to this point everything is OK, formatting is finished
...
kill `cat /var/run/enbd-client-2_disk_a.pid`
...
enbd-client server:30000 -n 1 -i 2_disk_a -m -t 0 -b 4096 -e /dev/ndb
# Client seems to connect OK
mkfs.ext3 /dev/ndb

#########################################
At this point mkfs hangs on a disk sleep, and enbd-client loops doing:
   ioctl(4, 0x4004ab0b, 0x40018008)        = -1 ETIME (Timer expired)
(fd4 == /dev/ndb)

System is linux-2.6.3 + nbd-2.4.32, /proc/nbdinfo says:

Does anybody have a clue why?
