Description of problem:
Running a kickstart installation with PXE reports many error messages on console
F4 and hangs forever during postinstall.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Kickstart with PXE
Actual Results: The unattended installation starts and shows the following
error messages on console Alt-F4:
<6>attempt to access beyond end of device
<6>01:01: rw=1, want XXXX, limit 4608
Those two lines are repeated with incremental values for XXXX. The lowest value
for XXXX I could see on the console was 7418 (couldn`t scroll back more), it
went up to 7488.
Installation will run through then by installing RPMs. Once the postinstall
starts, the progress bar will hang at a little bit less than half and on console
F4 appear again the two famous lines mentioned above. The final value of XXXX is
Two more lines appear at the bottom of F4:
<4>Error -3 while decompressing! <4>c02a0a3c(-1296616283)->c4b2a000(4096)
Then nothing happens anymore.
Expected Results: Installation should run through and finish by rebooting.
A side effect is, that once the installation hangs in the postinstall, not a
single command on console F2 can be executed anymore. All you will get is
I tested it on two machines, one a standard PC and the other one a PE4600 from
Dell. I`ve installed both systems w/o any problems over PXE with RedHat 7.1,
To eliminate the possibility of a bug in the kickstart file, I copied it on a
bootnet floppy and run a "linux ks=floppy". Installation ran through flawlessly.
Created attachment 57104 [details]
Kickstart file used for unattended installation over PXE.
I forgot to mention that I tried both PXE initrds (initrd-everything.img and
initrd.img), the result was the same.
You need to be sure to pass ramdisk_size=8192 on the kernel command line from PXE.
If that's not the problem, feel free to reopen the bug.
Thanks for your quick answer!
ramdisk_size=8192 indeed fixed the "attempt to read beyond end of device"-problem.
Installations run through now. :)
The "Alt-F2"-problem remains, though, with a different error message. I get
"<command>: not found" for any <command> I enter except mknod (maybe there are
others, but it`s pretty tough to find anything with ls not working...).
Maybe the PATH ist just not set correctly?
echo $PATH works and returns:
Doing a "chroot /mnt/sysimage" at the end of an installation to check if my
postinstall scripts worked etc. helped me a lot in the past and I`d gladly see
it working in RH7.3, too. Thanks.
