arcserve-KB : How to Unload the xofs driver on linux/Unix platforms.

Last Update: 2015-12-15 22:31:27 UTC

Description:  How to Unload the xofs driver on linux\Unix Platforms

If some of the directories were inadvertently left under xofs control during the uninstall procedure (for example, the scenario was running and the directory was mounted by xofs), the uninstall procedure cannot unload the xofs driver from your system.

In this case, you can either reboot the computer or unload the xofs driver manually.

To unload xofs drivers:

  1. Check if there are any xofs mount points using the following command:
  2. #cat /etc/xofs_mnttab
  3. Stop all the processes that hold your directory. Use the fuser command appropriate for your platform to discover processes that have open files in your directory:

AIX and Solaris:

#fuser -c

Linux:

#fuser -u

  1. Use the following umount command for the directory discovered in step 1.
  2. #umount
  3. Check that no process is using the xofs driver and manually unload it. Follow the appropriate instructions for your platform:

AIX:

Run as Root the following command to check whether xofs is loaded into the kernel:

echo lke | kdb| grep xofs

Run as Root the following command to unload the xofs driver:

/opt/CA/ARCserveRHA/bin/xoctl u /opt/CA/ARCserveRHA/bin/xofs.ext

Solaris:

Run the following command to check whether the driver is loaded into memory:

modinfo|grep xofs

Run the following command to manually unload the xofs driver:

modunload -i

Linux:

Run the following command to verify that the reference counter of the xofs driver is 0:

/sbin/lsmod|grep xofs

Run the following command to manually unload the xofs driver:

/sbin/rmmod xofs
