Subject: [PATCH 322/335] glusterd: display correct rebalance data size after
|
|
|
9f5ccc |
glusterd restart
|
|
|
9f5ccc |
|
|
|
9f5ccc |
Problem: After completion of rebalance, if glusterd is restarted,
|
|
|
9f5ccc |
rebalance status displays wrong rebalance data size in its output.
|
|
|
9f5ccc |
|
|
|
9f5ccc |
Cause: While glusterd restoring the information from /var/lib/glusterd/
|
|
|
9f5ccc |
into its memory, glusterd fetches rebalance_data from
|
|
|
9f5ccc |
/var/lib/glusterd/vols/volname/node_state.info. This value is
|
|
|
9f5ccc |
converted into an integer using atoi(), which is returning
|
|
|
9f5ccc |
incorrect value for larger values.
|
|
|
9f5ccc |
|
|
|
9f5ccc |
Solution: use sscanf() instead of atoi() to convert string to
|
|
|
9f5ccc |
integer(in this case it is unsigned long)
