Dear All,
I've tried to upgrade a Centos 3.3 installation to 4.0 using YUM and
some instructions I found in a thread on the Centos Forum.
The initial problem I had with Python 2.3/2.2 has been resolved, and now
I am trying to upgrade the kernel to 2.6 prior to the yum upgrade,
unfortunately it bails out at the end with dependancy erros on Xfree86.
At this point I decided to use the CDs with a the "upgradeany" option.
This went fine initally but then bails out with a swap error, this is
because swap on this machine is on /dev/md2 (a mirrored set) and this
was not set up at the original install time, as all the other partitions
were: when the machine was installed, one of my staff did not set the
swap up mirrored, so I had to mirror the swap partition manually after
the original install. This works fine, but the machine cant enable the
swap at boot becuase it does this prior to enabling the RAID subsystem,
so the swap startup fails, but once the machine is up, the swap is
actually running without any manual intervention. Its this error, that
stops anaconda from upgrading the OS from the CDs
I note on other machines I have installed when the swap was mirrored on
the original install, it still appears to enable swap prior to the RAID
subsystem, without any errors. So I guessed this might be a problem
with the ram disk image, so I created a new one using mkinitrd, but the
swap still fails at startup, thus preventing me from using the CDs to
upgrade the box.
I guess I could set the swap back to an unmirrored set, run the upgrade
from the CDs then mirror it again, but this is not ideal, does anyone
have any suggestions as to how to fix this little RAID niggle with the
swap caused by not RAIDing the swap parition originally on install?
Regards
Pete
