Errors: fatal: Bad handle c1c176c4 != 00000000!

Hi, i started tesing a storge cluster configured as follows:


Server "data1" (192.168.1.1)
slackware linux 9.1
kernel 2.4.22
enbd 2.4.32
enbd-server 6661 /dev/hdc1 -i data1 -b 4096

Server "data2" (192.168.1.2)
slackware linux 9.1
kernel 2.4.22
enbd 2.4.32
enbd-server 6662 /dev/hdc1 -i data2 -b 4096

Server "data" (192.168.1.3)
slackware linux 9.1
kernel 2.6.16.16
enbd 2.4.32
enbd-client 192.168.1.1:6661 -n 1 -b 4096 /dev/nda
enbd-client 192.168.1.2:6662 -n 1 -b 4096 /dev/ndb

Now when i start enbd-client this is the dmesg output:

ENBD #3868[0]: fixup_slot failed to find slot for pid 1630 ioctl MY_NBD_SET_SIG arg bff6a9d0 (61746164)
ENBD #3868[1]: fixup_slot failed to find slot for pid 1628 ioctl MY_NBD_SET_SIG arg bfb2a000 (61746164)

mdadm --create /dev/md0 --level=1 --bitmap=/root/md0bitmap -n 2 /dev/nda /dev/ndb

And the device is created correcly.

now i type:
mkreiserfs -b 4096 /dev/md0

The journaling process stops at abut the 80% and the dmesg start to print lines and lines of these errors:

ENBD #1165[15]: enbd_rollback (0): rollback req c1c176c4!

I don't understand anything.
