Hi there
In an Oracle RAC cluster using ACFS (as file-system) where we have a samba
server for sharing files to windows clients, we are suffering a strange
issue, from time to time, which it causes the Windows clients lock for a
while (10 min or a bit more) or even indefinitely when they are working
with the share resource, and sometimes we have to re-start the samba
service to come back to normality
We thought the problem was on the ACFS locks (incompatibility with samba
locks), so we tried to avoid them using some parameters in smb.conf but
unfortunately we are still having problems
Data:
OS: RHEL 6.4
samba server: samba-3.6.9-151.el6_4.1.x86_64
Oracle: 11.2
