Managing an MD Device
Stopping the MD Device
Stopping the MD Device
After you create an MD device, it begins to run. You need to stop the device and add the configuration into the raid.conf file. To stop the MD device, run the following command:
# mdadm -S <md_device name>
When you stop this device, all resources that were previously occupied by this device are released. Also, the entry of this device is removed from the /proc/mdstat file.
Example A-1 Stopping the MD Device /dev/md0
To stop the MD device /dev/md0, run the following command:
[root@dlhct1 dev]# mdadm -S /dev/md0
Once you stop the device, the entry is removed from the /proc/mdstat file. Following is an example of what the file contents will look like:
[root@dlhct1 dev]# cat /proc/mdstat
Personalities : [raid1]
unused devices: <none>
NOTE | This command and the other commands described subsequently are |
| listed as they may be used during cluster development and during some |
| recovery operations. |
