HI all,
I just did a fresh C7 install using kickstart.
fdisk -l /dev/sda shows:

win-xp guest after reboot: could not open disk image /dev/sr0: mo medium found and extreme sluggisch
Hi, 
win-xp won't boot after installation. The CD is needed to boot from. How can I 
convince win-xp to boot?
That's what I did: 
==================
I installed win-xp guest on debian squeeze: 
# virt-install --connect qemu:///system --name winxp-prof --ram 1024 \
--disk path=/dev/vg-levo/winxp-kvm,size=10 \
--network bridge:br0 --vnc --os-variant winxp --cdrom /dev/sr0

Strange (?) device.map in CentOS 7 VM installations
Hello,
After repeated failing efforts to restore CentOS 7 backups (taken using 
mondorescue software), I have found that all my CentOS 7 installations 
(VMs under KVM) have the same /boot/grub2/device.map, which seemingly 
refers to two HDs, although the VMs in fact include only one (virtual) HD.
For example: /boot/grub2/device.map
    # this device map was generated by anaconda

Kickstart putting /boot on sda2 (anaconda partition enumeration)?
Does anyone know how anaconda partitioning enumerates disk partitions when
specified in kickstart? I quickly browsed through the anaconda installer
source on github but didn't see the relevant bits.
I'm using the centOS 6.10 anaconda installer.
Somehow I am ending up with my swap partition on sda1, /boot on sda2, and
root on sda3. for $REASONS I want /boot to be the partition #1 (sda1)

mountmgr doesn't recognize d:: link to /dev/sr0
I am a Fedora 13 user, so HAL automounts CDROMs and DVDROMs on /media/<LABEL> (this node is also dynamically created and removed from the /media/ directory as needed).
II would like to assign a device drive letter to /dev/sr0 to reference any CD or DVD when inserted (e.g. d:: --> /dev/sr0), instead of having to manually create a symlink to the dynamically created /media/<LABEL>

Working example of logical storage pool and volume creation?
Hi all,
Does anyone have a working example of creation of a logical storage pool 
and volume?
I'm hitting a wall getting logical volumes to work on RHEL 6 beta.
There's a single drive I'm trying to setup (sdc) as a libvirt managed 
logical storage pool, but all volume creation on it fails.
Here's what I'm finding so far:
   Prior to any storage pool work, only the host

Yeah, probably some 'rpm -qV' (or whatever the command to verify all
packages is) could help as well.

Slow RAID resync
OK todays problem.
I have a HP N54L Microserver running centos 6.5.
In this box I have a 3x2TB disk raid 5 array, which I am in the
process of extending to a 4x2TB raid 5 array.
I've added the new disk --> mdadm --add /dev/md0 /dev/sdb
And grown the array --> mdadm --grow /dev/md0 --raid-devices=4
Now the problem the resync speed is v slow, it refuses to rise above
5MB, in general

creating partitions on a 2.7TB drive
Hello, sorry for the long email, it's a little hard to explain this issue. The gist of it is that the Ubuntu version of parted allowed me to do something which perhaps should not be allowed i.e. creating partitions on a 2.7TB drive when the partition table is not *gpt* but *msdos*.
I am trying to configure 2 identical servers, both are Dell Poweredge 2970 machines with 6 disks in them

Mailboxes not showing up in MS Outlook
Sat, 19 Jul 2014 15:03:03 -0400
I am not sure exactly where the problem is here. I am using a sieve script
that sorts various incoming messages into their own mailbox. MS Outlook does
not show those folders if they are not directly under INBOX.
EXAMPLE:
drwx------  31 vmail  vmail   1.0K 2014-07-19 14:46:55 EDT ./
drwx------   3 vmail  vmail   512B 2014-07-02 13:52:03 EDT ../

how can I tell what's on the MBR of /dev/sda?
Subject says it.
I would like to find out if I have anything written on the MBR of a disk 
in my system /dev/sda, or any other device.
If there is something there, is it readable, or recognizable to humans?
thanks,

Question Fe and BE device
Hello,
I try to install some applications on XEN. These applications have a 
automated install and are based on SLES10SP3. During the installation 
the device searches for /dev/sr0. Which fails in the xen enviroment. I 
now make a work around with booting a rescue system and mounting 
/dev/hdc and so on. But it should not be that difficult to install 
something into XEN.

sha256sum a dvd
CentOS-6.9
I am trying to verify a locally created dvd.  I am using sha256sum in
this fashion:
sha256sum /dev/sr0
Which gave this result:
sha256sum: /dev/sr0: Input/output error
So I tried this:
sha256sum /dev/cdrom
Which, after some time, also produces:
sha256sum: /dev/cdrom: Input/output error
What does this mean and how do I fix it?
