Always considered best practice to have OS and data/VMs on separate drives. Can use same controller. For example, I use two small drives to ZFS RAID-1 Promxox and rest of drives for OSDs. As for the controllers, the drama with Dell PERC RAID controllers in HBA/IT-mode using the megaraid_sas...

When PVE 8 was going EOL in one-week, I backed up the /etc directory and existing LXCs (don't run any VMs) via the native backup functionality. Did a clean install of PVE 9 and restored the LXCs. LXCs came up with no issues. I didn't do an upgrade because didn't want to deal with a one-off...

I had a use case to mounting a non-boot/root encrypted ZFS pool. This was for a bare-metal Ubuntu machine. As you know, Proxmox is Debian with an Ubuntu kernel. Called this systemd unit file "late-zfs-mount.service". I made sure it was the very last systemd unit file to run on the system, so...

None. These are headless Proxmox Ceph cluster nodes at work. Workloads are Linux VMs. I am guessing passing through a discrete GPU is another set of problems. At home, I have a Supermicro 1U server with a Intel CPU with integrated Quicksync. It gets passthrough to the Jellyfin LXC created by...

I am guessing you are running the latest BIOS and firmware for the R630. Using E5-2650L v4 without issue in production. Yes, I do have I/OAT DMA and X2APIC enabled. Do NOT have SR-IOV enabled because don't need it. Don't know if matters, I use Dell Intel X550 rNDC NICs running latest firmware.

So far, E810 issues have been resolved at work. As with all things, one must do their own due diligence and test their own infrastructure. YMMV.

I don't enable SR-IOV on the 13th-gen Dells at work in production. Running without issues. I do enable X2APIC and I/OAT DMA though. All servers are running latest firmware (BIOS, NIC, iDRAC, etc, etc).

At work, the order of precedence for reliability is: 1) Mellanox (CX-6) 2) Intel (E810) 3) Broadcom (NetXtreme/Thor)

Probably a long shot but the only clusters I manage at work are Ceph. Not ZFS. For testing, try setting the VM cache to none/default (obviously reboot the VM). YMMV.

I found out through trial-and-error live migrations with Ceph, I had to set the VM cache to none/default. Started doing this way back with Proxmox 6. Today's AI bots confirm this is correct setting for Proxmox Ceph live migrations. YMMV. I don't use ZFS on clustered machines except mirroring...

LOL, as I mentioned before, to avoid megaraid_sas driver drama, get a Dell HBA330 (which are cheap to get and uses the LSI3008 chip) which is a true IT/HBA-mode controller. Flash with latest Dell firmware. It uses the much simpler mpt3sas driver. No issues in production.

Since the base reference PowerEdge server for the E660 is the R650, it should work. I suggest you "de-brand" it to a standard R650. That requires flashing the PowerEdge Identify Module, factory reset the iDRAC, then flash the R650 BIOS, iDRAC, and any other firmware (NIC, etc).

Missing the the '-N/--no-hostonly' option for dracut which loads all drivers for initrd. This is my procedure way back migrating from ESXi to Proxmox https://forum.proxmox.com/threads/debian-11-not-booting-with-virtio-scsi-single-but-works-with-vmware-pvscsi.144806/post-652170

Need to be more specific on installation issues. I have successfully installed Proxmox 9 on Dell PowerEdge R730s (all R730s are updated with latest firmware) which is equivalent to a HPE DL380 GEN9. I did have to enable X2APIC and I/OAT DMA in the UEFI/BIOS though. I use Balena Etcher to...

Just did a clean install of my Supermicro home rack server from PVE8 to PVE9. Yeah, I wait until the last minute. No worries, I've been clean installing PVE9 at work on Dell servers since PVE9 came out. Prefer clean installs. Got punked too many times with major operating system upgrades...
