Re: [Linux-cluster] SEMI OT. Synchronizing jboss cache dir.





There is a good documentation at http://www.drbd.org/ search for
primary-primary mode and make sure the replication channels is the same as for
the cluster communication to avoid split-brain and data corruption

I´ll check it, thanks

you should format and mount /dev/drbd0 which is made on top of /dev/sda1, not
/dev/sda1 itself

for now this kind of device drbd0 is totally strange for me ;-). 

I´m going to read about drbd and I suposse I´ll finally understand it, 

Thanks again,
