Can anyone point me towards a pre-built kernel 2.6.20 for CentOS 5?
I need the later version to run Yosemite backup. I thought I was being clever and installed a Fedora kernel and it worked 99%, sadly the bit that didn't was the tape device which rather spoiled things.
thanks, Kevin Thorpe

what part of the .20 kernel is required ? could you just backport the driver once and for all and not need to worry about it then ?
Just download the source code for whatever version you need and compile it yourself. This isn't as painful as it sounds.

Yes, it really can be that painful and much moreso. Depending on how it's built, all sorts of random issues will creep up. Anything from not enough random data for ssh connections to function, to wtmp failure for login records to application malfunction. We're not even talking about future upgrades breaking because they rely on a particular kernel rpm being installed (think iptables) or the complete lack of upgrade path for security updates in the future. Rebuilding is a BAD idea.
It's much more sane to simply try to backport the module.
You're welcome to rebuild your own kernel all you want. However it's not 'recommended' advice. If it breaks, you get to keep all the pieces.
Compiling a new kernel isn't a one way trip.
Since you can boot multiple kernel images it's pretty easy to just revert back to what was working.

Exactly, it's a repeat many times trip. Each time there is a new bugfix/sec.fix you'll have to redo (and re-test) your kernel. These things quickly cost more than you'd expect...

Yeah, but it isn't as CentOS as it sounds, either. The distributed kernels have up to 700 patches (2.6.9 last time I counted) against them, stuff tends to get backported into the released kernels, there are performance patches and other patches for whatnot in that kernel.
So yes, it might be that it is easy to just compile the kernel. But the outcome might not be what you expect it to be.
Cheers,
Ralph
Agreed.
It's not a one way trip ... you can always revert back.

I run Yosemite backup on EL4, which has a much older kernel than Centos5.
What does not work and what error message do you get?

When I start ytadmin after a reboot I get a message in the alerts: Error 4463 - Kernel version not supported due to a bug in the scsi generic kernel driver. Device access restricted to file based devices only. It also mentions something about not supporting 2.6.18 and needing 2.6.20. I've seen comments about tape blocksizes on some versions of the kernel. I suspect that's what the problem is.
When I loaded the Fedora 2.6.20 kernel the system ran perfectly ok but the tape just kept giving me Input/Output errors, even in mt and tar. I'm not particularly surprised at that though, it is a different distribution even if it is related.

What kind of backup software does not support EL5/Centos-5? Contact the software vendor. It's also quite likely that any bugs in the 2.6.18 scsi layer is fixed in the centos 2.6.18.
