Sorry, but I have to ask: why increase the root to such a large size if it's more sensible to create new logical volumes for those directories using the most space, eg /usr or /opt?
If you
really need to increase the root filesystem itself:
- Take a backup!
- Verify that backup!
- Do not continue unless you did both steps!
- Increase the size of the LVOL
- Reboot into single-user mode
- Resize with the tool appropriate to your filesystem (ext2resize for Ext2/Ext3, resize_reiserfs for ReiserFS, xfs_growfs for XFS, mount -o remount,resize / for JFS)
- Reboot and verify everything is still working
- Do not throw away your backup until you're absolutely sure everything works

This is actually a VxVM question. I have a volume/filesystem spread over 4*146G disks. Now I want to shrink the filesystem - which I can do using vxresize. However, I want to shrink so that two of the four disks that the filesystem occupies are removed from the volume. Can I do that? (3 Replies)

Is it possible to resize a filesystem by resizing the LUN on RHEL 6.4 64-bit with LVM and no impact to running applications? The research I have done so far seems to take the approach of adding a new LUN and then expaning the volume group to the new LUN. I'm looking for an approach that avoids a... (7 Replies)

memprobe
MEMPROBE(1) General Commands Manual MEMPROBE(1)
NAME
memprobe - ROOT utility to examine memory usage
SYNOPSIS
memprobe [options]
DESCRIPTION
To activate the memory checker you have to set in the .rootrc file the resource Root.MemCheck to 1 (e.g.: Root.MemCheck: 1) and you have
to link with libNew.so (e.g. use root-config --new --libs) or use rootn.exe.
When all this is the case you will find at the end of the program execution a file memcheck.out in the directory where you started your
ROOT program. Alternatively you can set the resource Root.MemCheckFile to the name of a file to which the leak information will be written.
The contents of this memcheck.out file can be analyzed and transformed into printable text via the memprobe program (in /usr/bin).
