Me again! I now have a successful build of lustre server with ZFS support, thanks all for your help with this. I'm now stuck on getting ldiskfs support to work - specifically it requires the kernel-debuginfo and debugsource packages, which on Rocky 8.6, don't
exist for the kernel I'm building against (4.18.0-372.9.1.el8.x86_64). I've installed the only ones that exist, for kernel 4.18.0-477.15.1.el8_8 and hackily symlinked it to the current kernel to get lustre to build against it, which it does, but then it fails
on applying patches, which I suppose is not surprising. I assumed that having the e2fsprogs devel installed would do the trick but the build is specific in looking in /usr/src/kernel and /usr/src/debug/kernel, neither of which have it.</div>

I'd like ldiskfs support as we currently run this fs on the MDT. However, we're only doing that because when we put the filesystem in place (which was a while ago) I'd read a fair amount warning against using ZFS on MDT due to potential performance issues.
I've had a trawl through the mailing list and I can't see anyone having issues with newer ZFS versions so I guess my question is, is this still a thing? I've been planning to move to ZFS at some point anyway and it seems like this would be a good opportunity
to do so but I thought I'd check and see if anyone had any advice.</div>
