direct links of old sources may well be a few messages off.


Hi,
 
I have ran into a similar problem with Symantec Backup Agent running on the
same network and for some reason killing the tcp/ip stack.  More than likely
this issue will be related to the network. Any chance of sharing your
configs?
 
Cheers,

Subject: [DRBD-user] DRBD Sync stalls



Hi,

Does anybody have an idea how should I troubleshoot the following problem?

 

My peers were connecting and syncronizyng without any problem until network
guys introduced a firewall between the peers
(this is all in my lab but I wanted to emulate remote site replication)

As you can see the peers are still connecting OK and synchronization starts
but in a few second it stalls and remains in this state for ever.

 

What is even worse is that this introduces some kind of kernel problem as
with time the machine becomes inaccessible through ssh.

Ping is alive but no telnet can be established to any of the active service
ports.

 

Please help with any troubleshooting suggestions or ideas!

 

Thanks!
