I am looking for opinions and personal experience on CentOS7 for both grid and virtualized web environments. I am currently on CentOS6.5 in a production environment.
I am about to add about 50 more servers to my grid and am trying to identify the advantages and disadvantages of going to CentOS7. The good part is, that I have some tolerance for backing out and installing CentOS6.5 if 7 does not work out.
I read the comments about what CentOS7 brings but want to make sure that I am not introducing undue risk. Not seen a lot of issues with it.
I also have a small private cloud (VMWare esxi) and wanted to know if anyone was using CentOS7 there.
The basic question: Should I be holding off a little longer on going to CentOS7 in production?
On the one hand, we're starting to roll it out... *only* on new servers, and the servers we're rolling it out on are *only* fileservers - a couple attached to RAID boxes, and the other two will be attached to RAIDs, but server home directories.
I feel that I'd stay with 6.x unless there's a must-have feature. Right now, I'm playing with stuff on those servers - for one, NetworkMangler is *extremely* noisy, and trying to find *full* examples of its configuration file... I've only found *tiny* bits and pieces. I think I got it to log only errors, but the startup was *noisy*, and the documentation leaves something to be desired.
Oh, and it enables wireless. On a server. With no wifi. And I don't see any ifcfg-'s to set them to *off*.
I really don't like this "we'll do everything" attitude, esp. when "everything" is intended for users of laptops....
And the install, as I think I posted last week, was nasty - if I want anything other than it's "let me partition *and* throw LVM on top", it goes to choose disks... and selects *ALL* by default.
So there's a bunch of stuff I don't like, and will wait to see if they fix it.
