Boot sector getting full

offworld21 · August 17, 2011, 9:51am

Hi

System: FreePBX 2.9.0.7, installed from an AsteriskNOW 1.7.1 distro and fully updated to Asterisk 1.8.5.0 as of 17.08.11

After a yum update in the last two days I noticed the /boot sector is now yellow and at 70%. This is the highest it’s been and caused me some concern. I ran uname -r to check what kernel was in use which returned 2.6.18-238.19.1.el5PAE. I then ran rpm -q kernel and this was the following output:

kernel-2.6.18-194.17.4.el5
kernel-2.6.18-194.32.1.el5
kernel-2.6.18-238.9.1.el5
kernel-2.6.18-238.12.1.el5
kernel-2.6.18-238.19.1.el5

I attempted to remove the old kernels to free up space, however, my attempt failed due to dependency issues:

rpm -e kernel-2.6.18-194.17.4.el5
error: Failed dependencies:
kernel-i686 = 2.6.18-194.17.4.el5 is needed by (installed) kmod-dahdi-linux-fwload-vpmadt032-2.4.0-1_centos5.2.6.18_194.17.4.el5.i686
kernel-i686 = 2.6.18-194.17.4.el5 is needed by (installed) kmod-dahdi-linux-2.4.0-1_centos5.2.6.18_194.17.4.el5.i686

Should I remove the old kernels or do I need to free up space another way?

TIA

Hi

Still having issues trying to remove un-needed kernels from my PBX.

When I try and remove old kernels by running rpm -e kernel-2.6.18-194.26.1.el5 for example, I get the following error:

error: Failed dependencies:
kernel-i686 = 2.6.18-194.26.1.el5 is needed by (installed) kmod-dahdi-linux-2.4.0-1_centos5.2.6.18_194.26.1.el5.i686

Can anyone suggest how to ‘trim the fat’ in my boot sector please.

TIA

Any update?

Slow down mate…I had the same trouble (not so bad after all) you have and I solved (freeing /boot partition limited space by removing unused Kernels) in this way (which, IMHO, is far more secure than removing kernels as you’re trying to do) in my FreePBX Distro (which is CentOS 6.4 based).

Kind regards, Davide.
