8.2 with 9.0 kernel?
I have a couple of 8.2 servers that I exclusively use to run Samba. I need to upgrade to a newer kernel, and I'm wondering if it is safe to just upgrade to the latest 9.0 kernel, or if I need to upgrade the full distribution. Background: Recently I have had a couple of kernel lockups. I'm not too concerned about that, but they in turn caused some file corruption on files that had been in use hours before, but not at the time of the lockup. I've done research and this is a problem with XFS 1.2, which is what I am using on those servers. (Included with the 8.2 kernel.) XFS 1.3 is supposed to have this issue resolved. ie. There was apparently a sync bug in XFS 1.2 that kept files from being flushed to disk on a regular basis. With 1.3 the disk cache is sync'd to disk every 30 seconds like it should have been all along. The 9.0 kernel has XFS 1.3 (or 1.3.1) included. Thanks Greg -- Greg Freemyer

Any reason why you can't just build a new kernel from www.kernel.org? 2.4.23 is now the latest. Running it here with xfs. -- +----------------------------------------------------------------------------+ + Bruce S.

I've done it in the past and can do it again, but for production servers I really believe there is a value-add from the SUSE distro kernels. One simple example is if there is a security issue with a kernel. If it is a SUSE kernel, then SUSE will patch it and release an updated kernel via YOU. If it is a vanilla kernel, then you are on you own. Admittedly, it is not that hard to do yourself, but I like knowing that SUSE is out there looking for issues and fixing them for me. One less thing I have to do. Greg -- Greg Freemyer

Yeah, that'll be just fine--they're both 2.4 kernels. It's only when going with 2.6 one might need some util upgrades. -- Mads Martin Joergensen, http://mmj.dk "Why make things difficult, when it is possible to make them cryptic and totally illogical, with just a little bit more effort?" -- A.
