CentOS 5.3

With Red Hat Enterprise 5.3 released I figured it was time to talk about CentOS 5.3 which is an almost identical copy to RHEL.  As always Hawk Host runs the latest and greatest so CentOS 5.3 will be showing up on our servers once it’s available.  For the most part like any upgrade it’s seamless no one notices as package updates don’t mean any reboots or down time.  This is one thing worth noting though and that’s a new kernel!  So within the next month there are going to be maintenance notices for every machine to have a 5-10 minute down time in order to reboot the machine.  So that’s means users making tickets during the reboots as they fail to keep up with maintenance notices.  Even if we sent emails about this sort of maintenance notice we’d have complaints that this is unacceptable or they do not want maintenance notices at all.  Those are the few that do read them as most do not after our experience with the reseller name server IP change where a large amount of resellers did not bother to change IP’s until their sites went down.

Well here’s some information about the RHEL 5.3 release although more technical than anything I figure worth posting:

    I make it a habit to read your forums and blog 😀

    Not only does it tell me when my site may go down (which isn’t often) it also lets me know when I’m going to be stuck doing work (i.e. upgrading our work server to 5.3!!!)

    Luckily for the most part Linux doesn’t take after the “Bill Gates School of Upgrades” and everything goes like it should.

    Thanks for the great service!

    Congratulations with the blog – it makes for a very enjoyable and informative read!
    Having this insight into how your company operates certainly does give me a good impression, as someone who is currently evalulating the market and looking for a new web host.

    Here are a few points that have occurred to me following what I have read so far:

    1) This article suggests that Centos5.3 would be installed within a month of the post date. I’d just like to clarify that 5.3 has not yet been released, and is still not due for a couple of weeks yet.

    2) Can I suggest that you publish a mainentence schedule for planned maintenance, stating which time periods (pref at the weekend) that you will usually perform any updates or upgrades? I am concerned that, with most of my clients in the UK, your US working hours may conflict with our busiest period. Along with this, your timezone and main working hours would also be valuable information.

    3) Just a trivial point, while I think of it, your blog has no link back to your main website (as far as I can tell).

    That’s it for now.
    Thanks for listening! 🙂
    Hal
