Resizing est4 filesystem while mounted
Greetings -
I had a logical volume that was running out of space on a virtual machine.
I successfully expanded the LV using lvextend, and lvdisplay shows that it
has been expanded. Then I went to expand the filesystem to fill the new
space (# resize2fs -p /dev/vde1) and I get the results that the filesystem
is already xx blocks long, nothing to do. If I do a # df -h, I can see that

Failing to start or create VM, cannot connect to hypervisor host

Selecting raw logical volumes during guest VM creation
Greetings -
I have stepped through the first guest OS installation (a testing VM) on my
new server and have a technical question that I hope someone might be able
to help me with. I have exhausted my google search ability and have not
been able to find the details I am looking for. In general the question I
am trying to answer is how to select and use multiple raw logical volumes

Issue with hard links, please help!
Hello,
Sometimes when creating hard links to the rsync destination directory,
it seems like the new directory (created from the cp -al command) ends
up with all the data. This causes a problem in the sense that if the
rsync destination directory had 21GB, after the cp -al command, it ends
up having only 8mb, then the rsync source directory determines that it
now requires 21.98GB to update the

[PATCH] kinit/kinit.c
A patch for a few more hiccups and trivialities in kinit.c:
* The check_path() calls check for "/root" and "/old_root" - I believe
that should be "/root" and "/root/old_root".
* chdir("/") is recommended after pivot_root()
* init_argv[0] isn't set properly to the basename pointed to by char *s

Confusion over steps to add new logical volume to guest VM
Greetings -
I am hoping someone can confirm for me the steps that I am using to add an
LV to an existing Guest in KVM, and what I am seeing as I do some of these
steps. My host (earth) is CentOS 6 and so is my guest (disect). The guest
(disect) is my testing server. The main objective of what I am trying to do
is add a logical volume for /var into my guest. The LV (lv_disectvar) is

[patch] trivial cleanup
remove 'NFS-Root' from an error message, and get rid of the old_root
check, as it's unused and fails if the target filesystem is mounted

Resize ocfs....?
I've tried several times to resize one of my ocfs volumes[see emcpowere1 below]
I'm on the latest [prod] version of ocfs/ocfs-tools as of 3pm EST on 18JUL04.
Per instructions...
Take down db, unmount all ocfs drives, use ' tuneocfs -F -S 100G /dev/emcpowere1 '
Supposedly this should work, but I get get....
The size specified, 100G, is larger than the device size, 59G.

libvirt support for qcow2 rebase?
I have not found support in libvirt (nor virsh) for doing the equivalent
of "qemu-img rebase ....".
The use case:
You have copied a qcow2 stack and the new files have different names or
reside in a different directory. Therefore you need to change the
backing file.
Is there a way to do this? Is this a planned addition to libvirt?

[PATCH 0/8] switch_root() enhancements
On a train ride to Bruxelles, brought out my axe and directly attacked
run_init(8). run_init(8) is dead, long live switch_root(8).
The next run on switch_root(8) involves fdopendir,
so another push for the upcoming stdio 1.6 branch.
The following is boot tested with initramfs-tools,
kinit(8) tests would very much be appreciated!?

help with signal from monitor
I have an Alienware laptop that has Nvidia GTX 880M hardware driven by
this driver. I recently purchased an ASUS_VN289H monitor. When my system
gives a blanking command, the monitor returns some sort of lost signal
message which causes the monitor to unblank and the time out I requested
is cancelled. This is probably more of an HDMI question than specific to
this hardware, but I was wondering
