[PATCH 1/1] appliance: init: Avoid running degraded md devices
'--no-degraded' flag in the first mdadm call inhibits the startup of array unless all expected drives are present.
This will prevent starting arrays in degraded state.
Second mdadm call (after LVM is scanned) will scan unused yet devices and make an attempt to run all found arrays even they are in degraded state.
Two new tests are added.
This fixes rhbz1527852.

lvm errors after replacing drive in raid 10 array
I thought I'd test replacing a failed drive in a 4 drive raid 10 array on
a CentOS 5.2 box before it goes online and before a drive really fails.
I 'mdadm failed, removed', powered off, replaced drive, partitioned with
sfdisk -d /dev/sda | sfdisk /dev/sdb, and finally 'mdadm add'ed'.
Everything seems fine until I try to create a snapshot lv. (Creating a

LVM encryption and new volume group
Hi Chris,
thanks for your answer.
It is the first time I decided to encrypt my lvm. I choosed to encrypt the volume group, not every logical volume itself, because in case of doing lvm snapshots in that group they will be encrypted too?
And how do I create a new encrypted volume group?
Regards
Tim

Setting up large (12.5 TB) filesystem howto?
Hi,
I'm trying to set up an iscsi 12.5 TB storage for some data backup.
Doing so, I had some difficulties to find the right tool, maybe it's
also a question of the system settings...
The server is a 32Bit CentOS 5.3 with the recent updates. Ths iscsi
connection can be establised.
fdisk and parted fail to create any information on the device or fail
completely.

best practice backup
Hi there,
I am using tar to backup the whole system (specific directorues usr,lib,sbin,etc,var,home,root).
On bare metal recovery I install the minimal portion of the syetm and then I throw the tarballs.
Any opinions?

LVM recovery after pvcreate
Hi all,
I had centos 5.9 installed with one of its volumes (non-root) on LVM:
...
/dev/vgapps/lvapps /opt/apps ext3 defaults 1 2
...
Then installed centos 6.4 on this servers but without exporting this volume (I wanted to reuse it).
After that instead importing it I did:
# pvcreate /dev/sddlmac
# vgcreate vgapps /dev/sddlmac
And then realised that I should have

LVM Input/output error
Hi,
I recently installed centos for the first time and I like it!
Also, I just started working with lvm. The following warnings
are genertated whenever I run one of lvm commands on the external
usb disk (MyBook by Western Digital).
* What could be the source for those messages?
* Should I worry about them (writing into the created LV's
seems to work)?
* If yes, how to fix them?

RE: RedHat DomU hanging
Hello,
Maybe someone can help me.... I have a guest XEN image that ran well until today. I use an LVM partition to host the guest and today on Dom0 I added another LVM to be available to this domU.
This were all the commands I issued :
On hypervisor
lvcreate -n lintra02data -L 30G rootvg

what''s correct way of shrinking LVM based domU?
Hi all
I want to shrink one of my LVM based domU''s, but don''t quite know how to
do it.
I have searched the Wiki & HOWTO''s, and they all show you how expand /
enlarge a LVM based domU, but not shrinking it.
So, I stopped (destroyed) the domU, and then resized it as follows:
lvresize /dev/data/cpanel1 -L10GB (It was 100GB), but when I a started

[PATCH] mkfs: add 'label' optional argument
Add the 'label' optional argument to the mkfs action, so it is possible
to set a filesystem label direct when creating it. There may be
filesystems not supporting changing the label of existing filesystems
but only setting it at creation time, so this new optarg will help.
Implement it for the most common filesystems (ext*, fat, ntfs, btrfs,
xfs), giving an error for all the others, just

For this test I created a 40GB lvm volume group with /dev/sdb and /dev/sdc

then a 60GB VDO vol (for testing purposes)
