Checking and resynchronizing stale mirrors
You can check if there is a stale mirror on any of your file systems. If there is a stale mirror, the stale mirror needs to be resynchronized, and the resynchronization process needs to be verified.
To check if there are stale mirrors on your file systems
- To check if your file systems contain a stale mirror, enter the following:
Storage> fs checkmirror
For example, to display the file systems that have a stale mirror, enter the following:
Storage> fs checkmirror fs_name: -------- mirror3
To resynchronize all stale mirrors or a stale mirror for a specified file system
- To resynchronize all stale mirrors or a stale mirror for a specified file system, enter the following:
Storage> fs resync [fs_name]
where fs_name is the name of the specified file system where you want to resynchronize for stale mirrors.
If you do not include fs_name, you resynchronize all the stale mirrors for all your file systems.
For example, to resynchronize all stale mirrors for all file systems, enter the following:
Storage> fs resync Resync stale mirror for file systems are started in background.
For example, to resynchronize all stale mirrors for a specified file system, enter the following:
Storage> fs resync mirror3 Resync stale mirror for file system mirror3 is started in background.
To verify the resynchronization process for your stale mirrors
- To verify the resynchronization process for your stale mirrors, enter the following:
Storage> fs checkresync
For example, to display the resynchronization progress running in the background, enter the following:
Storage> fs checkresync FS MIRROR TYPE PROGRESS START_TIME WORK_TIME ================================================================================== alltask_roll tier 1 ROLLBACK 0.16% Jun/20/2011/19:12:45 0:0:3 alltask_roll tier 2 ROLLBACK 0.29% Jun/20/2011/19:12:45 0:0:3 alltask tier 1,mirror 02 RESYNC 1.56% Jun/20/2011/21:20:02 0:4:18 alltask tier 2,mirror 02 RESYNC 0.21% Jun/20/2011/21:33:20 0:0:4 fsrelayout tier 1 RELAYOUT 0.04% Jun/20/2011/21:48:02 0:26:15 fsrelayout tier 2 RELAYOUT 9.44% Jun/20/2011/21:48:28 0:25:49 REMAINING_TIME ============== 30:29 17:01 4:30:54 32:03 1119:33:44 4:07:40
Note:
If a column addition to a file system is in progress, the output of the Storage> fs checkresync command will include RELAYOUT status.
