Boot Partition Problems

llbbl · 08-01-2006, 03:29 PM

I installed this machine a while ago when FC3 was the newest thing out. It has a couple HD's in the machine. I forget the size and how many. We have been using nightly Yum updates to keep everything running smooth. When it was installed I decided to use software raid controller to create Logcial Volumes. Here is the disk layout:

Code:

~$ df Filesystem 1K-blocks Used Available Use% Mounted on 
/dev/mapper/VolGroup00-LogVol00 120365124 2985716 111166596 3% / 
/dev/sda1 101086 91025 4842 95% /boot 
/dev/shm 256576 0 256576 0% /dev/shm

The problem is that we are no longer able to run Yum because /boot is full of crap. I think it is putting everysingle dot release of the kernel in there so that now there is no more room. I don't want to delete anything and cause problems.

How big should the /boot partition be if we want to run Yum nightly? 500 MB ? Can I delete the older kernel versions?

-rw-r--r-- 1 root root 1639539 Jun 2 2005 vmlinuz-2.6.11-1.1369_FC4

After installing FC5 on a different machine I noticed that the /boot partition wasn't very big either. I do not want to run into the same problems. Please advise.

yum shouldn't be installing kernels wildly at all. you csay the partition is full, yet you've not given us an ls output to show what actually is there...! run "rpm -qa | grep kernel" and see what kernels currently are installed. you only need to one that matches the output of "uname -r", other ones can be very safely removed.

I didn't give you full ouput but I quoted the earliest kernel that is in the /boot folder. The latest one that is installed is vmlinuz-2.6.16-1.2096_FC4smp. Why do you want to see all of them? There are at least 10 different ones along with system.map files initrd and config files associated with each version of the kernel.

[llbbl@localhost boot]$ rpm -qa | grep kernel
kernel-smp-2.6.14-1.1653_FC4
kernel-2.6.16-1.2096_FC4

kernel-smp-2.6.16-1.2096_FC4

Ok there is all of them.

Ok so this is the command to remove the versions I dont want right?

Quote:

rpm -e kernel_version

I wonder if I can write a cron job to run and delete everything but the current version.

ok, so assuming you don't have a multi cpu system, start by running "rpm -e $(rpm -qa | grep kernel-smp)" that'll nuke the smp ones, then fine tune further pulling out old normal ones you no longer want.

llbbl · 08-01-2006, 03:52 PM

I am running SMP version, so I want to keep those.

Sorry I didn't say what uname -r says. Thats good info thou.

llbbl · 08-01-2006, 04:05 PM

Yea it's all fixed. Back down to 24%. I really need an automated way to get rid of those. TYVM for the help.

acid_kewpie · 08-01-2006, 04:08 PM

in my experience yum will always remove the kernel before last, only leaving the two newest ones. is your yum itself totally up to date... bit of a stupid question i guess if it's all automatic, but that behaviour isn't exactly great.

I tried yum update but had this problem.

Hopefully I figure this out and get yum to update the system than yum will stop doing this with the /boot partition.

I guess you have redirect yum to the legacy site?

I got it working after a bit of work.
