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_socket</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 command.
How can don't stop RegionServer and delete the bad disk.
Thanks,
LiuLei

LiuLei,
Using your example you can run umount -l /disk10 ( Lower case L ) on the disk and it will lazy dismount and will not wait for a disconnect.

Subject: umount bad disk
To: user@hadoop.apache.org<ma...@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_socket</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 command.
How can don't stop RegionServer and delete the bad disk.
Thanks,
LiuLei

LiuLei,
Using your example you can run umount -l /disk10 ( Lower case L ) on the disk and it will lazy dismount and will not wait for a disconnect.
