I tried using Ceph twice at home. Once was via Proxmox, and it installed and ran perfectly fine, although tbf I didn't load it with much.
The next was via Rook, since I have a Kubernetes cluster, and it was a nightmare. I spent a week or so reading through all the docs I could find before I felt prepared to go through with it, only to have random clock sync issues that Reddit informed me were due to me enabling power savings mode in the BIOS for my nodes.
ZFS's biggest hiccup for me is when I do a kernel update and DKMS borks the upgrade. Other than that, it's been rock-solid. I run a normal and backup node with it, no regrets.
- gkhartman 4y agoI solved the ZFS DKMS bork issue by moving to Debian 11 from Centos 8. I've had zero openZFS issues since the move. On Centos it would require work every time a sufficient kernel upgrade came in. Since I'm familiar with RHEL I just swapped some of the Debian default services for RHELish alternatives (Firewalld, Podman, etc.).
- sgarland 4y agoI'm also using Debian; have been since Wheezy. I also template my VMs with Packer/Ansible though, so in the event it gets too messy or annoying to fix, I just export the pool and import it to a new VM. The last issue I had was that linux-headers didn't get installed with the kernel update, so DKMS couldn't build on them. I assumed they were a dependency for zfs-dkms, but no.
