Yum failing in update

unix1adm · 11-24-2009, 01:59 PM

I was trying to update my OS using yum and get...

Total size: 46 M
Is this ok [y/N]: y
Downloading Packages:
Running rpm_check_debug
Running Transaction Test
Finished Transaction Test

Transaction Check Error:
installing package kernel-2.6.18-164.6.1.el5.x86_64 needs 4MB on the / filesystem
installing package cups-1.3.7-11.el5_4.4.x86_64 needs 4MB on the / filesystem

Error Summary
-------------
Disk Requirements:
At least 4MB needed on the / filesystem.

Not sure why.

So I am assuming I need to increase root. I found this link but not sure if this is the correct command:
http://kbase.redhat.com/faq/docs/DOC-3175

parted /dev/mapper/VolGroup00-rvg_root print

Model: Linux device-mapper (dm)
Disk /dev/mapper/VolGroup00-rvg_root: 1074MB

Also found this link...

http://kbase.redhat.com/faq/docs/DOC-3175

one talks about parted and one talks about lv commands.
I dont seem to have this command on my system
ext2online
no man or anything
What is my best method to grow root? this is a prod system so I dont want to do the wrong command.

unix1adm · 11-24-2009, 02:09 PM

I am guessing i need to do

lvextend -L+256M /dev/mapper/VolGroup00-rvg_root
Then i would need to do (if the command was there)
ext2online /dev/mapper/VolGroup00-rvg_root

But I dont have ext2online command
mount
/dev/mapper/VolGroup00-rvg_root on / type ext3 (rw)

This may be a problem with yum ...
see....
https://bugzilla.redhat.com/show_bug.cgi?id=495911

nasty bug and almost caused me to corrupt my prod system.

i would reinstall and give more room to / and /home

yes resizing a LVM is nice but it can be a pain to do if new to linux
/ = 992M LESS that one gig for the top root ????? what???????
/home = 992M
/usr = 3.9G
/var = 992M
/tmp = 992M
/boot = 99M
?? tsom = 20G
-- what --

try something like this
/tmp - not needed
/var -- not needed
/usr - might not be needed if there are only 1 or 2 users

Code:

/boot 72 to 100 meg 
/ 9 gig  ( 4 gig should be THE VERY smalest min. used) 
/home 5 gig 
tsom ??? the rest of the drive 
swap = 1 to 2 gig

Reinstalling is not an issue for me. This is a prod system. I could have sworn when it was built root was given 1G

unix1adm · 11-25-2009, 04:41 AM

I did a "yum clean all" and that cleaned up the other errors I had. I did have that bug. Not to increase root.

unix1adm · 11-25-2009, 04:52 AM

When the box was built it was set to the following so not sure why it has smaller partitions.

/boot - set by the system ( ~200 MB)
/ - 1024 MB
/usr - 4096 MB
/var - 1024 MB
/home - 1024 MB
/tmp - 1024 MB
/opt - 1536 MB
This is its sister system and yum works fine. They both have more than 4M on /

tsom is our application directory... Not RH.

unix1adm · 11-30-2009, 09:29 AM

this is what i did by the way...
lvextend -l 42 /dev/VolGroup00/rvg_root

Then;
resize2fs /dev/mapper/VolGroup00-rvg_root
(resize trhe filesystem to expand to fill the entire logical volume).

df -h

OK so after many tries and restores etc this upgrade still fails horribly. I still have a 9.04 disk around that I imaged but I decided on a clean install of Ubuntu and fedora12 and Have successfully migrated my user data over to the new system.

If I get the urge int he next few days/weeks when things slow down for the holiday I may try this again and strip the user of any custom setting like comiz etc and see what happens.
