Unable to change virtual machine power state: The process exited with an error: End of error message. Thanks, VMware!

Today I wanted to test the raid5 reshape feature of Linux kernel >=2.6.17. My testing environment was VMware with 3 virtual disks each containing a partition of 200MB which should be resized to 500MB, using grml (featuring kernel 2.6.17-grml) of course. For real-live setup adjust the steps for stuff like switching harddisks of course. ;-) […]

vim-outliner let’s you use vim as an outline editor: # apt-get install vim-vimoutliner % $PAGER /usr/share/doc/vim-vimoutliner/README.Debian % vim ~/foo.otl :he vo If you want to export the otl file into HTML take a look at otl2html.py. Oh, did I already mention that vim-outliner is shipped with grml? ;-)

iwatch is a realtime filesystem monitoring program. It’s a simple perl script to monitor changes in specific directories/files and send email notification immediately. It reads the dir/file list from a xml config file or via commandline and needs inotify support in kernel (Linux Kernel >= 2.6.13). If you are using Debian/grml you can install a […]

Now I’m back again. Sorry for the downtime of grml.org and michael-prokop.at, the server was running out of mem (thanks to Robert for bringing it up again). A server upgrade will follow in the near future anyway. Now 3746 unread blogpostings, 716 mails in my inbox, lots of unread mailinglists and newsgroups are waiting for […]

JFYI: I’ll be offline for holidays in the next few days. I won’t be reachable via phone nor via instant messaging nor via irc nor via mail. EOF

Given: server with SCSI disk for the system plus a SCSI storage in the back. The SCSI disk uses another driver than the SCSI storage. Installing Debian etch via grml is no problem, the system disk is /dev/sda, the SCSI storage is bound to /dev/sdb. But: who guarantees that /dev/sda is always the systemdisk? Using […]

Want to install Debian etch? But the Debian etch-ISO does not detect all the necessary hardware? Or it even does not boot at all? Or you just can’t find your Debian etch CD-ROM? Or having $ANOTHER_PROBLEM? Use grml. :-) Take a look at my Debian etch via grml Howto. You can get this tip via […]

A RedHat 9 server had problems with its rpm database. Running strace showed that it’s hanging when accessing /var/lib/rpm/Packages (a Berkeley DB, wondering?). No rpm actions were possible anymore. Solution: # cd /var/lib # cp -a rpm rpm.backup # rm -f /var/lib/rpm/__db* # rpm -vv –rebuilddb

Yes, online resizing isn’t possible just with xfs but starting with Linux kernel 2.6.10 you can do it with ext3 as well. With e2fsprogs >=1.39-1 new filesystems are created with directory indexing and on-line resizing enabled by default (see /etc/mke2fs.conf). A short demo how online-resizing running on top of LVM works: cfdisk /dev/hda # create […]

Just feeding google and interested readers. DRI worked with X.org 6.9 but with version 7.0 it’s failing? % LIBGL_DEBUG=verbose glxgears libGL: XF86DRIGetClientDriverName: 1.5.1 i915 (screen 0) libGL: OpenDriver: trying /usr/lib/dri/i915_dri.so libGL error: dlopen /usr/lib/dri/i915_dri.so failed (/usr/lib/dri/i915_dri.so: cannot open shared object file: No such file or directory) libGL error: unable to find driver: i915_dri.so Ok, missing […]

Don’t forget – today (on 28th of july) we have the System Administrator Appreciation Day! Thanks for reminder, koki :)

Because it’s definitely worth a read: the proceedings of the Linux Symposium 2006 are now available for download (direct links: Volume 1, Volume 2 – PDF). Have a nice week reading them. :-)

First of all: thanks a lot to IBM/Lenovo! Michael Gebetsroither and me were working on the ‘Trusted Live Linux’ project at IAIK @ TUG. IBM/Lenovo kindly provided us a Thinkpad T60 1951-44G laptop so we were able to test and work with a TPM v1.2 chip. The results of the project will be available within […]

The black grml shirts will be available on linuxdays Graz 2006 at the grml-booth. The yellow and the pink shirts are available in the grml-shop at spreadshirt. The grml-CDs will be available with the upcoming LinuxUser magazine 06/2006! Oh, I won’t sell my laptop. ;-) BTW: being proud owner of 1000 grml-CDs rocks. :-) PS: […]
