Subject: umount bad disk
To: user@hadoop.apache.org
I use HBase0.96 and CDH4.3.1.
I use Short-Circuit Local Read:
<property>
 <name>dfs.client.read.shortcircuit</name>
 <value>true</value>
</property>
<property>
 <name>dfs.domain.socket.path</name>
 <value>/home/hadoop/cdh4-dn-socket/dn=5Fsocket</value> </property>
When one disk is bad, because the RegionServer open some file on the disk, so I don't run "umount", example:
sudo umount -f /disk10
umount2: Device or resource busy


umount: /disk10: device is busy
umount2: Device or resource busy
umount: /disk10: device is busy

I must stop RegionServer in order to run umount comm= and.  
How can don't stop RegionServer and delete the bad disk.
Thanks,
LiuLei
