Hi guys,

Seem to have hit a snag on a 2.6 FC2 machine running drbd-0.7.5-3

This pair had been running fine for a couple of months, then the Primary 
(Machine A) died, a manual failover worked and we're currently running 
on the Secondary (Machine B).

Machine B is now running and in WFConnection. Whenever I try to sync 
Machine A back up with it I get a hard kernel panic:
Sep 26 11:41:54 ipadca kernel: drbd2: Secondary/Unknown --> 
Secondary/Primary
Sep 26 11:42:00 ipadca kernel: drbd1: [drbd1_worker/3807] sock_sendmsg 
time expired, ko = 4294967295
Sep 26 11:42:03 ipadca kernel: drbd1: [drbd1_worker/3807] sock_sendmsg 
time expired, ko = 4294967294

time expired, ko = 4294967289
Sep 26 11:42:24 ipadca kernel: drbd1: [drbd1_worker/3807] sock_sendmsg 
time expired, ko = 4294967287
Sep 26 11:42:24 ipadca kernel: drbd1: Got NegRSDReply. WE ARE LOST. We 
lost our up-to-date disk.
Sep 26 11:42:24 ipadca kernel: Kernel panic: drbd1: Got NegRSDReply. WE 
ARE LOST. We lost our up-to-date disk.

I tried to "drbdadm invalidate all" on Machine A, but had no luck...
I notice in the CHANGELOG for drbd 0.7.6 that "'drbdadm invalidate 
[res]' was not working correct", perhaps that is why I can't invalide my 
Machine A.
Is there some other way I can invalidate the data so the sync happens ok?

Is it possible to upgrade my Machine A to 0.7.6 whilst leaving Machine B 
on 0.7.5 (They both use proto 74, but different api's)????

The big problem is that these machines are about 400km away in the 
middle of the Australian outback :)

Any suggestions would be most appreciated.

Cheers

Jon
