I'm trying to set up two standalone JMS servers, MS1, MS2 using JBoss 6.3 EAP. While the primary will come up and creates folders/files (bindings, journal, & large-messages) on the shared drive the backup reports an error every time. The error indicates some kind of permissions problem but I'm not sure with what. For troubleshooting, I tried switch the two (made MS2 primary, MS1 backup) to make sure they're both able to write to the shared drive which they do. But the backup server never comes up and reports the same error. Tried googling this error but I come up with nothing. Any ideas?
