We have a Slackware 9.1 box that our ASP controls. We use it to see the logging of our Weblogic-clusters.
All the logging is auto-mounted in /rmt which is fine, as long as you know the names of the mountpoints. When you don't access the mountpoints for a certain period of time, the mountpoint... (0 Replies)

xen-resize-guest
XEN-RESIZE-GUEST(8) Perl Programmers Reference Guide XEN-RESIZE-GUEST(8) NAME
xen-resize-guest - Resize a loopback or LVM based xen guest. SYNOPSIS
xen-resize-guest [options] Help Options: --help Show help information. --manual Read the manual for this script. --version Show the version information and exit. --verbose Show diagnostic output. General Options: --add Specify the amount of space to add, e.g. --add=1gb --dir Specify the path to the loopback image root. --force Force the resize to happen without a last-chance delay. --hostname Specify the hostname of the guest to resize. OPTIONS
--add Specify the amount of storage to add to the primary disk. --dir Specify the directory where the loopback files are based. --force Don't pause for 10 seconds prior to commencing. --help Show help information. --hostname Specify the hostname to delete. --lvm Specify the volume group to use. --manual Read the manual for this script. --version Show the version number and exit. DESCRIPTION
This tool will ease the resizing of Xen guests, whether they are based upon loopback files or LVM partitions. Whilst the process of resizing a guest is pretty simple it can be fiddly to do the steps correctly in the right order: 1. Shutdown the guest. 2. Unmount the volume, if it is mounted. 3. Add to the space. 4. Check the filesystem. 5. Resize the filesystem. 6. Restart the guest. More than once I've heard of users making mistakes and breaking their filesystems; hence this tool. AUTHORS
