I use HBase0.96 and CDH4.3.1.

I use Shor= t-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_socket<=

</property>

When one disk is bad=
, because the RegionServer open some file on the disk, so I don't run &=
quot;umount", example:
sudo umount -f /disk10
umount2: Device or=
 resource busy


umount: /disk10: device is busy
umount2: Device or resource busy
umou=
nt: /disk10: device is busy

I must stop Reg=
ionServer in order to run umount command.

How can don't stop RegionServer and delete the =
