    Default Centos update = system failure .. Please advise

    Night all,

    Today i did some software updates of the linux OS centos.. I did read through most of the changes that would happen when i do..

    Sadly enough on reboot my softraid(raid1) was broken in the update and there isnt any way to fix it..and the drives wouldnt boot in single mode.. so i am going to use a live cd to copy my /opt/zimbra folder(havent run a backup for a week or 2).

    My problem is that i want to move away from CEntos onto Ubuntu (this gives me the best opinion to do this)

    any pointers.. or advice.

    I have read this "Moving ZCS to New Server - Zimbra :: Wiki"

    but i dont know if that would apply to my situation.

    PS please dont laugh at my softraid.

    I am currently running 5.5 and was about to do an update. Wondering now if I ought to hold off.

    Anyone else out there running CentOS 5.6 64-bit ?

    Were you using Intel Software Raid by any chance ?

    I did a little searching, and if you search google for

    "Centos kernel upgrade breaks dmraid on Intel Software Raid"

    you will find a lot of information on what may be your issue. If I read it right, it seems like if you boot your old kernel it might start up correctly - but I haven't delved into it too much.
