環境
- Red Hat Enterprise Linux 6.5
- multipath
- XFS
問題
- We are copying(rsync) data from current file system to new file system but after few GB copied the job aborted.
- System log shows these errors:
Jan 18 23:46:53 multipathd: checker failed path 8:96 in map mpatha

決議
- Add the queue_if_no_path (or no_path_retry=queue) option to the multipath configuration.
- Unmount and check the XFS filesystem for any on disk errors due to the shutdown.
