<div class="">Hi Andreas,<br class="">
<br class="">
Thank you for your insightful reply. I didn't know Rocky; I see there's a version 9 as well - is ver 8 better, since it is more mature?<br class="">

There is an el9.2 ldiskfs series that would likely also apply to the Rocky9.2 kernel of the same version. We are currently using el8.8 servers in production and I'm not sure how many people are using 9.2 yet. On the client side, Debian/Ubuntu are widely used.</div>

<div class="">You mention zfs, which I really liked when I worked on Solaris, but when I tried it on Linux it seemed to perform poorly, but that was in Ubuntu; is it better in Redhat et al.?<br class="">

I would think Ubuntu/Debian is working with ZFS better (and may even have ZFS .deb packages available in the distro, which RHEL will likely never have). It's true the ZFS performance is worse than ldiskfs, but can make it easier to use. That is up to you.</div>

<blockquote type="cite" class="">The first yes toon to ask is what is your end goal? If you just want to build only a client that is mounting to an existing server, then you can disable the server functionality:<br class="">
./configure --disable-server<br class="">
and it should build fine.<br class="">
If you want to also build a server, and *really* want it to run Debian instead of eg. Rocky 8, then you could disable ldiskfs and use ZFS:<br class="">
./configure --disable-ldiskfs<br class="">
You need to have installed ZFS first (either pre-packaged or built yourself), but it is less kernel-specific than ldiskfs.<br class="">

My best guess is that it is because the running kernel version doesn't exactly match the kernel source tree, but I can't seem to find that version. Am I right - and if so, where would I go to download the right kernel tree?<br class="">
