How to resize filesystem by resizing the LUN without impact to applications.?
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 new LUN this as we virtualize all of our Linux. Not requiring a reboot is very important.
Thanks in advance.

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)

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.
