Subject: [PATCH 540/540] extras: Disable write-behind for group samba.
|
|
|
b7d4d7 |
|
|
|
b7d4d7 |
when write-behind is enabled with Samba it could be a
|
|
|
b7d4d7 |
source of data corruption. The translator, while
|
|
|
b7d4d7 |
processing a write call, immediately returns success but continues
|
|
|
b7d4d7 |
writing the data to the server in the background. This can cause data
|
|
|
b7d4d7 |
corruption when two clients relying on Samba to provide data consistency
|
|
|
b7d4d7 |
are operating on the same file.
