Sunil, I'm confused. You advice me to get e newer kernel version, xen doesn't work beyond 2.6.18 kernel version, so I'm planning to leave it and migrate to a regular environment in this way I could obtain up to 2.6.26 kernel version from Debian Backports, but when I went to ocfs site to look for a suitable ocfs2 version for that kernel, I can't find any package beyond 2.6.18.92! Following my questions: - why seems old to you my kernel version? - what could be more stable? 1 Centos 5.2 (kernel 2.6.18.92.1.13) with ocfs2 1.2 or with ocfs2 1.4? 2 Debian's 2.6.26 kernel with ocfs2 1.2 or with ocfs2 1.4? - if I switch to Debian's 2.6.26, what version of ocfs2 can I use?

I know my kernel it's a bit old, but I'm not feel so brave to try a xen's kernel compilation.... I've talked about the case of a node crash, it never will shutdown the service orderly. In this case a with just one node running are there a way to keep it running avoiding panicing itself?

But for it to work correctly, it does require proper configuration. For example, correct service shutdown ordering. The FAQ explains one such issue that you are probably encountering. BTW, this version is 2.5yrs old. Upgrade to kernel 2.6.21+. Atleast.

For starters, (RH)EL5 2.6.18 is not the same as 2.6.18 mainline. Secondly, we backport the latest file system to enterprise kernels, (rh)el and sles. We do not backport to older mainline kernels. The fs in mainline 2.6.18 is very very old. If you are on an enterprise kernel, you could go with ocfs2 1.2.9 or ocfs2 1.4.1. ocfs2 1.4.1 is newer and thus has more features. If you are on (RH)EL5 U2+, go with 1.4.1. Debian uses the mainline kernel. Meaning you don't get a choice of the fs version. Use the one the distro ships. For more, refer to the ocfs2 1.4 user's guide.

Thanks for your quickly response... So to get miself clear, to resolve my ocfs2 issues I need to migrate to Centos 5.2 and still can use xen, because the point is on the quality of kernel nor on the version of it, does it?
