Re: Problems setting up Debian 7
After this error some more steps are taken. The system then reboots the only thing i get is a flashing underscore in the top left corner of the screen. Are you using a directly-connected console or some sort of serial console? When we see this problem, it's almost always an incorrect console setting on the command line of the newly-installed system, whether missing the serial console configuration or using the wrong speed, etc. The system is booting, just sending all the messages off into never-never land. Thanks for the reply. The PC is actually standing right next to me with its own screen. Did a short Google search but didn't find anything that might help me. Probably because i am not quite sure what i am looking for. Any hints on what and where i can fix this would be greatly appreciated. -- - Benedict Wright BSc Institut für Softwaretechnologie TU Graz Inffeldgasse 16B/II 8010 Graz tel.: 0316 873 5714 fax.: 0316 873 5706

If you would like compare your setup to a working one you might want to have a look at the Debian-LAN setup http://wiki.debian.org/DebianLAN>. Perhaps this helps in finding the error.

Re: Not all fixed. Re: Has anybody had good luck using FAI where it repartitions on a system that previously contained an lvm setup?
Hello, I'm worried I'm echoing in my own thread here, but here is what I've found: setup-storage depends on liblinux-lvm-perl While that library has been redone, both versions of it just seems to pass through the same problem. The ultimate problem is that logical volume information is derived from executing the "vgdisplay -v" command. The output from this command has changed between squeeze and wheezy. The older version of this command has fewer fields. snippet of older output: LV Name/dev/vg/var VG Namevg snippit of newer output: LV Path/dev/vg/var LV Namevar VG Namevg They've added a field, and changed what is contained in the old named field. I'm not sure if this is a change in the lvm tools or a change in the kernel interface, but it sure as heck messes with setup-storage. I'll go send a bug to the liblinux-lvm-perl debian package, but ultimately, I bet they just pass along another field as a fix. Anyway, apparently, this bug has legs. -Ken On 07/19/2013 05:14 PM, Ken Hahn wrote: > Hey, > > Still looking at this issue (been gone to a conference), but I'm noting > that FAI/debian changed from using liblinux-lvm-perl .14-2 to .16-1. > This ends up changing what the "current device tree" looks like. > Specifically it appears the lv's are represented by /dev/ paths in the > old version and by volume name only in the new version.
