My live mail server was due an update so I ran
yum update
All seemed file so I told it to proceed. HOwever it then hung for over 30
minutes.
I stopped the update and tried again. It complained about problems with the
update, so I tried
yum --skip-broken -y update
which then hung at a different place. After some Googling I tried
yum-complete-transaction
and
package-cleanup --cleandupes
both of which failed. I then using my "Microsoft" head I thought I'd try
rebooting to see if that fixes it. This of course was a big mistake as my
server now crashes on bootup.
I have managed to get it back up and running by selecting a version of the
kernel that is 3 versions old.
I have now tried
yum history
yum history remove 115 (which failed)
package-cleanup --cleandupes (which failed)
yum-complete-transaction (which failed)
yum-complete-transaction --cleanup-only (which worked)
followed by
[root@ollie2 /]# package-cleanup --problems

I'm now running
yum check
which has also taken 30 minutes so far.
Questions
1) Any ideas why my yum runs keep hanging, and what I can do to fix it?
2) How do I go about fixing the problems listed above?
3) What do I need to do to get my server back in a safe, consistant state?
