LV resize encrypted volume
Hi,
dom0: Debian Lenny 2.6.26-2-xen-amd64, domU: same. Xen 3.2-1
After resizing a LV on dom0, Xen is not reporting the new extended size
to the PV domU even though dom0 is well aware of the new size. I''ve
rebooted domU (not dom0 yet as that''s running a lot of other domU''s).
The LV I tried to resize is encrypted. Resizing unencrypted volumes
works as expected.

Expanding a virtual block device
Hi list.
I''m running Xen 4.0.1 on Debian.
I''m trying to live resize a block device :
- I have a arbitrary block device in my dom0 (/dev/mapper/vm-vol42).
- I start a PV domain with that device as a disk (disk =
[''phy:/dev/mapper/vm-vol42,xvda,w'']).
- I resize vm-vol42 in the dom0 (adding size only)
- the dom0 sees the device''s new size.

expand physical volume
Hi.
I added a disk to a hardware raid 5 array and now i want to expand the
LVM physical volume. There are now 4 sas 146GB disks in the server.
The virtual disk /dev/sdb from the raid controller has been resized
successfully with the server management software osma.
[root at srv1 ~]# fdisk -l /dev/sdb
Disk /dev/sdb: 438.4 GB, 438489317376 bytes

Using LVM snapshots to backup NTFS partitions for windows guests
Hi everyone!
I''ve been reading this list for a while and I''m thinking that the best
way to do backups is using LVM snapshots as discussed here several
times.
The problem is that when i use a LVM logical volume as windows disk,
windows writes the partition table onto the LV so the LV itself is not
a partition - it''s a whole disk.
lvm/device-mapper does not create the

Hi William, its the only HDD on that machine. All the partitions are
mounted. The error message refers to the HDD, not to any of the mounted
partitions.

Encrypting tmp swap and home
Hi everyone,
I added a page under the HowTos for Encryption, and then added a guide
for encrypting /tmp /swap and /home using cryptsetup and LUKS keys on
LVM, when you already have partitions setup.

potential wiki on encryption
Hello all,
I posted the whole disk encryption instructions in the forum that has been briefly discussed on the list. I joined the list per Ned's post on the thread.
http://www.centos.org/modules/newbb/viewtopic.php?viewmode=flat&topic_id=15923&forum=42
I have a couple of questions about the process of creating a wiki.
1. How does the peer-review process work?

Question re: CentOS-6.0, KVM, and /dev/sr0
I am experimenting with KVM and I wish to create a virtual machine
image in a logical volume. I can create the new lv without problem
but when I go to format its file system then I get these warnings:
Warning: WARNING: the kernel failed to re-read the partition table
on /dev/sda (Device or resource busy). As a result, it may not
reflect all of your changes until after reboot.

Re: ocfs2 and configfs.ko..fixed...but gnuparted has issues....
I was able to get the source code for ocfs2 and compile it. This worked and created the necessary .ko files
Now I have to figure out why gnu parted 1.6.15 has bugs. when I try a partprobe on a partitioned firewire maxtor drive
mount -t ocfs2 /dev/sdb1 /u01/oradata/orcl
It says no such device....
Any ideas anyone?...

CentOS 5 grub boot problem
- Ahh OK now I see why I was confused. The originally posted partition
map uses cylinders as units, not LBA. I missed that. Cylinder 1 is the
same as LBA 63. And that is sufficiently large for a GRUB legacy stage
2.
- OK this is screwy. Partitions 1 and 3 on both drives have the same
number of sectors, but partitions 2 differ:

Extending a CentOS disk without reboot
Hello,
Today a virtual server under my administration ran out of disk space, so
I had to get extra space to it.. while it was running, because it's an
important web server without any kind of HA/Load Balancing (don't do
that, kids).
So what happened, is that after another administrator had extended the
disk from VMWare, I tried to extend it from the OS side.
Everything went well,

How to make fdisk recognize increased iSCSI LUN?
Hello,
How to explain to fdisk that /dev/sda size changed? I increased LUN on storage, reloaded iscsi, did echo 1 > /sys/<something>/rescan. And I see in "dmesg" that kernel found new size of the LUN. But when I type "fdisk /dev/sda" it still shows old size. On /dev/sda1 sits LVM PV and I'd like to resize it instead of adding one more PV to volume group.

Rescan for new geometry without reboot?
Hello,
We just had our servers fitted with more disks. Most of the disks are
growing existing RAID 1+0 channels, some are in new channels.
Controllers and disks support live installation.
I'd like to avoid a reboot just to let the system find that the disks
are larger.
All I can find so far suggests that its possible to rescan the disks,
and even find the new geometry (e.g.

Can you convert Windows LVM domU to sparse img file?
I have a Windows 2000 domU running in an LVM partition. I need to move
it to another host, but none of my other xen servers have lvm or free
space to create an lvm. So I''d like to convert it to a sparse img file.
The file system in the domU is ntfs.
Can anyone suggest how to do this?
Thanks,

FW: FDISK Help please in Centos 4.3
Hi,
Is it possible to create one raid volume of 3.3 TB (9550SX-8lp X WD5000YS -
8nos) and create a file system with ext3? (CentOs4.3 64bit)
The maximum I am getting is 1.24tb and fdisk returns no more space
available. But when I say fdisk /dev/sda it list full size of 3.3 TB. But I
can not create partitions more than 1.24TB.
Any idea?
Thanks
