[Gluster-users] Issue with Samba over Gluster

[Irshad Ahmed]

Thanx....I will surely do what you have asked.
I was using 3.0.5...But had to remove it as my Jira Atlassian applications
were crashing and i dont know why.
So reverted back to 3.0.4 and they started working normally.
Whenever i mounted my gluster volume it used to show split brain afr error
in the logs.
But as far as samba is concerned it not working in 3.0.4 nor in 3.0.5.
I will send in logs asap.
