Byetzion 17/06/2006

HP MSA1000 controller failover
Byetzion 27/03/2007

HP MSA1000 is an entry-level disk storage capable of communicating via different types of interfaces, such as SCSI and FC, and can allow FC failover. This FC failover, however, is controller failover and not path failover. It means that if the primary controller fails entirely, the backup controller will “kick in”. However, if a multi-path…

This is a day full of events, so… My first – to allow tsclient to work under Ubuntu 12.04, you should follow this guide: http://superuser.com/a/547102 To sum it up: Get tsclient to your architecture from http://pkgs.org Install it using ‘sudo dpkg –force-depends -i tsclient_0.150-3ubuntu1_amd64.deb’ Edit /var/lib/dpkg/status ,…

Allow Postfix to call custom scripts by using mail aliases
Byetzion 11/01/202411/01/2024

Using custom mail aliases to run scripts is an existing practice. However, on modern Linux distributions it is blocked as a security risk. Following Postfix common guidelines do not allow for it to run the scripts. It reports the script as called, however – it does actually nothing. This has been verified on Oracle Linux…

Quick and dirty – modifying Boel initrd files manually
Byetzion 02/07/2007

Boel initrd files are actually compressed cramfs files. This is a menuscript for authoring and modifying these files, if needed. Assume the file in question is /tftpboot/install-initrd-i386.img: cp /tftpboot/install-initrd-i386.img /tmp/ cd /tmp/ gzip -S .img -d install-initrd-i386.img mount -o loop install-initrd-i386 /mnt mkdir initrd cd /mnt/ tar cf – . | (cd /tmp/initrd/ ; tar…

Radeon 9600 Dual Display (dual-head)
Byetzion 21/06/2006

After much agony with my faulted NVidia Dual-head card, and the frequent hard-freeze which were part of this experience. A new and shining ATI Radeon 9600 has entered my AGP slot, and I was ready to make it rock. First thing first – I utterly failed to install the damn driver. ATI build their drivers…

Hot-resize disks on Linux
Byetzion 06/04/202019/01/2022

After major investigations around, I came to the conclusion that a full guide describing the procedure required for online disk resize on Linux (especially – expanding disks). I have created a guide for RHEL5/6/7/8 (works the same for Centos or OEL or ScientificLinux – RHEL-based Linux systems) which takes into account the following four scenarios:…
