Subject: [PATCH 226/255] geo-rep : fix gluster command path for non-root
|
|
|
233933 |
session
|
|
|
233933 |
|
|
|
233933 |
Problem:
|
|
|
233933 |
gluster command not found.
|
|
|
233933 |
|
|
|
233933 |
Cause:
|
|
|
233933 |
In Volinfo class we issue command 'gluster vol info' to get information
|
|
|
233933 |
about volume like getting brick_root to perform various operation.
|
|
|
233933 |
When geo-rep session is configured for non-root user Volinfo class
|
|
|
233933 |
fails to issue gluster command due to unavailability of gluster
|
|
|
233933 |
binary path for non-root user.
|
|
|
233933 |
|
|
|
233933 |
Solution:
|
|
|
233933 |
Use config value 'slave-gluster-command-dir'/'gluster-command-dir' to get path
|
|
|
233933 |
for gluster command based on caller.
