Subject: [PATCH 491/511] glusterd: mount directory getting truncated on
|
|
|
b7d4d7 |
mounting shared_storage
|
|
|
b7d4d7 |
|
|
|
b7d4d7 |
Issue:
|
|
|
b7d4d7 |
In case of a user created volume the mount point
|
|
|
b7d4d7 |
is the brick path 'ex: /data/brick' but in case of
|
|
|
b7d4d7 |
shared_storage the mount point is '/'.So, here
|
|
|
b7d4d7 |
we increment the array by one so as to get the exact
|
|
|
b7d4d7 |
path of brick without '/', which works fine for other
|
|
|
b7d4d7 |
volumes as the pointer of the brick_dir variable is
|
|
|
b7d4d7 |
at '/', but for shared_storage it is at 'v'(where v is
|
|
|
b7d4d7 |
starting letter of 'var' directory). So, on incrementing
|
|
|
b7d4d7 |
the path we get in case of shared_storage starts from
|
|
|
b7d4d7 |
'ar/lib/glusterd/...'
|
|
|
b7d4d7 |
|
|
|
b7d4d7 |
Fix:
|
|
|
b7d4d7 |
Only, increment the pointer if the current position is '/',
|
|
|
b7d4d7 |
else the path will be wrong.
