DL140 Generation 1 (G1) and LILO do not work

Byetzion 14/02/2007

I add to this blog all pieces of information which I might think could help other people.

One of the things I have encountered short while ago had to do with DL140 G1 system cannot boot Linux.

It’s Linux system (RedHat 4 32bit) was deployed by an external system and the system could not boot. However, when installed from CD, the system booted just fine. The symptom for this was that after booting, the screen showed:

LILO: Loading Linux…..

and that’s all. The system could have booted (and did so once) after several days, however, this is not really a desired status.

It seems to be an issue of Lilo and this specific hardware. Other systems (non DL140) were able to boot just fine using Lilo, and this same kernel version was bootable on that system through other means.

Replacing Lilo with GRUB during installation/deployment solved the isse. FYI.

HP EVA SSSU and fixed LUN WWID

Byetzion 14/07/2008

Linux works perfectly well with multiple storage links using dm-multipath. Not only that, but HP has released their own spawn of dm-multipath, which is optimized (or so claimed, but, anyhow, well configured) to work with EVA and MSA storage devices. This is great, however, what do you do when mapping volume snapshots through dm-multipath? For…

Better iostat visibility of ZFS vdevs

Byetzion 04/07/202111/03/2023

All ZFS users are familiar with ‘zpool iostat’ command, however, it is not easily translated into Linux ‘iostat’ command. Using large pools with many disks will result in a mess, where it’s hard to identify which disk is which, and going to a translation table from time to time, to identify a suspect slow disk….

Selective dnsmasq logging (split dnsmasq logging)

Byetzion 31/10/202127/01/2023

My system provides DNS services, using dnsmasq, to several different subnets. I wish to log specific queries to different files – as I want to identify, and maybe even respond to certain DNS queries of the IoT network. The (excellent) utility dnsmasq is unable to split the logging into multiple log files, or filter logging…

Linux Software Suspend (swsusp2) – Impressive Stability

Byetzion 28/12/2005

I know hibernation is cool, and I know it’s possible even under Linux, but up to now, I’ve never had it as stable and reliable as one could have expected. However, using SWSUSP2.2RC on 2.6.14.2, I am impressed. I’ve been using my laptop for the last week or so, ever since I’ve discovered the problem…

Hard Freeze when Using FireFox, Unison-GTK, and some other GTK apps

Byetzion 26/05/2006

Hard freezes are unpleasant at best. They also prevent you from tracking the source of the problem. You speculate, based on the "familly" of applications you encounter problems with, and try to obtain some resolution. At first it was FireFox. I’ve removed it to install Galeon instead. Didn’t help. I left it at that, and…

XenServer “Internal error: Failure… no loader found”

Byetzion 24/10/2009

It has been long since I had the time to write here. I have recently been involved more and more with XenServer virtualization, as you might see in the blogs, and following a solution to a rather common problem, I have decided to post it here. The problem: When attempting to boot a Linux VM…
