Red Hat Bugzilla – Bug 508189
"/sbin/grub-install /dev/cciss/c0d0" results in unbootable system
Last modified: 2010-06-28 09:18:01 EDT
Description of problem:
If I run
to install GRUB, it complains
expr: non-numeric argument
and if I then reboot, the system hangs, displaying only "GRUB".
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. /sbin/grub-install /dev/cciss/c0d0
I get the following output:
# /sbin/grub-install /dev/cciss/c0d0
expr: non-numeric argument
Installation finished. No error reported.
This is the contents of the device map /boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.
# this device map was generated by anaconda
If I reboot, the system prints simply "GRUB" and hangs.
The OS is installed on an HP Smart Array Controller, device /dev/cciss/c0d0 and the following partitions:
/dev/cciss/c0d0p1 3020140 301340 2565384 11% /
/dev/cciss/c0d0p3 12096756 721628 10760644 7% /usr
/dev/cciss/c0d0p2 12096756 531176 10951096 5% /var
The problem is in the script's attempt to break up the device name into a disk and partition, for use by GRUB. (If I run instead /sbin/grub-install '(hd0)' everything works fine.) The regular expression to populate $tmp_part does not match (line 120 in my copy) so $tmp_part ends up as "/dev/cciss/c0d0" rather than "". Obviously that is an invalid partition number, and so later on the script tries to install GRUB on (hd0,) rather than (hd0).
I can fix the problem by adding
if echo $tmp_part | grep "^/dev" >/dev/null; then
immediately after the regular expression that populates $tmp_part, but this doesn't seem like the cleanest solution to me.
I also reproduced this bug.
Same bug in RHEL is closed errata.
This patch should apply Fedora's grub package.
grub version: grub-0.97-51.fc11.i586
RAID Controller: SmartArray E200
/dev/mapper/VolGroup00-LogVol00 215G 6.2G 198G 4% /
/dev/cciss/c0d0p1 190M 28M 153M 16% /boot
This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '11'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 11's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 11 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
