[DRBD-user] kernel traceback with 0.7.22

[Jon Nelson]

I'm not sure if this is the right mailing list or not.

I got this traceback while testing drbd between two machines. The
version I am using is 0.7.22 as built for openSUSE 10.2. I'm trying to
remember the exact conditions under which the tracegack occurred, but I
seem to recall that I did something like this:

P = "primary" (source), S = "secondary" (dest)

P: drbdadm disconnect notebook
P: edit /etc/drbd.conf and change protocol from 'A' to 'C', also change
   send buffer size from 512 to "commented out"
S: edit /etc/drbd.conf and change protocol from 'A' to 'C', also change
   send buffer size from 512 to "commented out"
P: drbdadm adjust notebook
S: drbdadm adjust notebook
P: drbdadm connect notebook <- this fails
P: drbdadm up notebook <- this also fails
P: rcdrbd restart <- this fails (drbd in use)
etc...

Eventually, I noted in the 'S' side the following in /var/log/messages

This is on openSUSE 10.2 (although latest 'default' kernel
from them) with the openSUSE drbd kernel modules and userland.
The version of the software is reported to be:

drbd-kmp-default-0.7.22_2.6.18.2_34-30
drbd-0.7.22-30

Is there anything else I can provide?
