| Fixed In Version: | samba-4.6.0-0 | Doc Type: | Bug Fix |
| Doc Text: |
In the samba configuration, by default the 'posix locking' is enabled and 'stat cache' is disabled. Enabling 'posix locking' sends the file lock request to the bricks too, and disabling 'stat cache' blocks samba to cache certain information at the samba layer. This led to decrease in performance of SMB access of Red Hat Gluster Storage volumes
As a fix, the following two options are included in the samba configuration file:
posix locking = No
stat cache = Yes
Due to this, a slight improvement in the performance is observed.
