Simple Install of x86_64 CentOS 5 is failing
It gets all the way through the install, and then when it reboots,
grub can't find the kernel. Grub can't find the kernel because the
kernel was not instaled for some reason? I looked at the box through
rescue mode and in /boot there is no kernel.
Any ideas what might have happened?
Cheers...james

/dev/console not getting created...
Hi All,
I've been trying to put together a one off CentOS 4 based distro, and
I ran into some trouble. First off just so you know we've been doing
this with CentOS 3 and with RedHat 9 before that, so the inexperience
is only with the delta between CentOS 3 and CentOS 4 (and RHEL 3 and
RHEL 4 by extension).
Anyway, the problem is that for some reason /dev/console is not
getting created.

fitCopula
I am using R 2.5.0 on windows XP and trying to fit copula. I see the
following code works for some users, however my code crashes on the
chol. Any suggestions?

can''t mount vfat fs on lvm created by winxp guest
Greetings,
I''ve had no success with mounting a vfat file system created by a
Windows XP guest on a lvm volume.
# mount -t vfat /dev/vg1/win1 /mnt/
mount: wrong fs type, bad option, bad superblock on /dev/vg1/win1,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

LVM & volume groups
Can anybody tell me if it makes a difference if domU''s have separate LVM
volume groups?
For instance, the Xen User Manual
( http://tx.downloads.xensource.com/downloads/docs/user/#SECTION03330000000000000000) says, when setting up a domU''s disks with LVM, to do a
vgcreate vg /dev/sda10
Should each domU have it''s own volume group, or can all the domU''s share

/proc/mounts always shows "nobarrier" option for xfs, even when mounted with "barrier"
Ran into a confusing situation today. When I mount an xfs filesystem on
a server running centos 5.4 x86_64 with kernel 2.6.18-164.9.1.el5, the
barrier/nobarrier mount option as displayed in /proc/mounts is always
set to "nobarrier"
Here's an example:
[root at host ~]# mount -o nobarrier /dev/vg1/homexfs /mnt
[root at host ~]# grep xfs /proc/mounts
/dev/vg1/homexfs /mnt xfs

dm-multipath use
Are folks in the Centos community succesfully using device-mapper-multipath?
I am looking to deploy it for error handling on our iSCSI setup but there
seems to be little traffic about this package on the Centos forums, as far
as I can tell, and there seems to be a number of small issues based on my
reading the dm-multipath developer lists and related resources.

Accessing console for Xen 4.0 with 2.6.31 pvops kernel on Dell Poweredge R610
I am currently using a Dell PowerEdge server R610 with Xen 4.0 installed and
the 2.6.31.13 pvops kernel.
I am accessing the server console using the iDRAC KVM feature of the dell
management console.
Does anyone know how to configure the console option in the grub menu so
that all the boot messages can be seen on the
mgmt console?
Currently I can view only the Xen bootup messages if I dont specify

Unwanted Levels in R
I searched the mailing list archives and found one post relevant to my problem,
but it was not specific enough to solve my problem.
I am reading in a large file of data (I believe it is in ASCII format). I have tried
reading the file in as a data frame and as a list, and both methods result in
unwanted levels being created which leads to problems when I try to copy
or reference certain cells.

live migration to localhost with lvm based storage
I have lvm based (thin pool) storage on local disks. I need to move
vps from one vg on one disk to another. Does it possible to migrate to
localhost with blockcopy migration to another vg?
I'm understand that i can move lv from one vg to another, but i don't need that.

mirroring with LVM?
I'm pulling my hair out trying to setup a mirrored logical volume.
lvconvert tells me I don't have enough free space, even though I have
hundreds of gigabytes free on both physical volumes.
Command: lvconvert -m1 /dev/vg1/iscsi_deeds_data
Insufficient suitable allocatable extents for logical volume : 10240

Any ideas?

Install ubunto domU
Dear *,
I''m more used to work with RedHat like OSes. Still, I did not denied the
request from a user who wants a domU based on ubunto. I usually use
virt-install to do the job, with a script similar to this one:

[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.
