Subject: [PATCH 328/335] glusterd: Add warning and abort in case of failures
|
|
|
e3c68b |
in migration during remove-brick commit
|
|
|
e3c68b |
|

Problem -
|
|
|
e3c68b |
Currently remove-brick commit goes through even though there were files
|
|
|
e3c68b |
that failed to migrate or were skipped. There is no warning raised to the user.
|
|
|
e3c68b |
Solution-
|
|
|
e3c68b |
Add a check in the remove brick staging phase to verify if the status of the
|
|
|
e3c68b |
rebalnce process is complete but there has been failures or some skipped files
|
|
|
e3c68b |
while migration, In this case user will be given a warning and remove-brick
|
|
|
e3c68b |
commit. User will need to use the force option to remove the bricks.
