Subject: [PATCH 205/221] glusterd: Can't run rebalance due to long unix socket
|
|
|
74b1de |
|
|
|
74b1de |
Problem: glusterd populate unix socket file name based
|
|
|
74b1de |
on volname and if volname is lengthy socket
|
|
|
74b1de |
system call's are failed due to breach maximum length
|
|
|
74b1de |
is defined in the kernel.
|
|
|
74b1de |
|
|
|
74b1de |
Solution:Convert unix socket name to hash to resolve the issue
|
|
|
