Boot Disks
rpool The sata disks will be linux boot disks in a standard linux raid (maybe zfs mirror?)
- underprovision the sata boot disks
hdparm -Np976762584 --yes-i-know-what-i-am-doing /dev/disk/by-enclosure-slot/sata-bottom
Note that you must power cycle (hard not a reset) the box to get the disks to take this.
SAS controller
The built in controller supports HBA mode per supermicro.
https://docs.broadcom.com/doc/pub-005110
I had to pickup an AOM-S3008M-L8 HBA, which fits in place of the included RAID controller, as even in JBOD mode the controller will not talk to the expanders allowing ledon to identify the failed disks.
https://www.reddit.com/r/homelab/comments/iqz7xc/supermicro_s3108_in_jbod_mode/
Doesn't work in JBOD mode, everything is proxied.
Updating Disks
Firmware
Current firmware on the disks is E004, but disks have E002 on them

Low Level Format
It's necessary to low level format these disks as we need to turn off Protection Type 2, test the sectors of the drive and make it a 4096 sector size.
# SeaChest_Format --protectionType 0 --formatUnit 4096 --confirm this-will-erase-data --poll -d /dev/sg2
NVME Config
This was the most dificult. The onboard NVME ports under the power supply will take a standard NVME cable, but do not supply any power. The M.2 to SFF-8612 adapters don't have a power connector, so I was able to add some 3.3v inputs on the filter cap. This was kinda hacky, but it works.
Optane
The optane SSD needs to be changed to 4k sectors, but the nvme command doesn't work. Intel has a intelmas program that does https://community.intel.com/t5/Intel-Optane-Solid-State-Drives/4K-format-on-Optane-SSD-P1600X/m-p/1477181

Phsyical layout
Mandatory config
The disks don't deal with the old NVME support on this box (it's listed as oculink .91, not 1.0) and there are some bugs in linux around this and power handling.
A config must be added to the kernel cmdline
vim /etc/kernel/cmdline
add this to it:
nvme_core.default_ps_max_latency_us=0 pcie_aspm=off
then
proxmox-boot-tool refresh
udev rules
https://www.reactivated.net/writing_udev_rules.html#strsubst
https://github.com/bkus/by-enclosure-slot
Updated code for the supermicro:
https://github.com/W9CR/by-enclosure-slot/tree/Supermicro-server
to get this working on boot with proxmox you need to do do the following:
in /etc/default/zfs ZPOOL_IMPORT_PATH="/dev/disk/by-enclosure-slot"
rm /etc/zfs/zpool.cache update-initramfs -u
then power cycle it and confirm the new names are in use. Once that's done run update-initramfs -u again to store the zfs cache in the initramfs (optional but boots faster)
iscsi target
https://forum.level1techs.com/t/has-anyone-here-tried-to-create-an-iscsi-target-in-proxmox/193862
https://www.reddit.com/r/homelab/comments/ih374t/poor_linux_iscsi_target_performance_tips/
mtu!
sudo ip link set eth1 mtu 9000
"Backstore name is too long for "INQUIRY_MODEL" iscsi"
Initator = client
target = server
Provision FatTony as the iSCSI Target
- create the iscsi point on the datastore
zfs create localDataStore/iscsi
- Install the server on FatTony
apt install targetcli-fb
- start the service
systemctl enable --now targetclid.service
- fix the missing /dev/<zpool-name>.
Per the latest debian they are only located under /dev/zvol/<zpool-name>.
This has a bug in proxmox, as the /dev/<zpool-name> is hard coded.
A forum post on it is here https://forum.proxmox.com/threads/missing-path-to-zfs-pool-in-dev-dir-after-recent-updates.139371/
KERNEL=="zd*", SUBSYSTEM=="block", ACTION=="add|change", SYMLINK+="%c" >/etc/udev/rules.d/99-zvol.rules
Prepare the Proxmox Clientnodes
Now on the clients we need to configure the access to the iscsi target so it can ssh to it. It does this to run ZFS commands and make the block devices that are exported
The IP of the target here in the keyname is important, this is used by PVE as the default. IPV6 is equally possible.
mkdir /etc/pve/priv/zfs ssh-keygen -f /etc/pve/priv/zfs/192.168.8.187_id_rsa ssh-copy-id -i /etc/pve/priv/zfs/192.168.8.187_id_rsa.pub root@192.168.8.187
- verify this key works
ssh -i /etc/pve/priv/zfs/192.168.8.187_id_rsa FatTony
- Read out the ISCSI Initiator name from each node
for i in carbonrod moleman fink spiderpig fattony ; do ssh $i 'cat /etc/iscsi/initiatorname.iscsi | grep ^InitiatorName' ; done InitiatorName=iqn.1993-08.org.debian:01:5f09136632 InitiatorName=iqn.1993-08.org.debian:01:28601263f0ff InitiatorName=iqn.1993-08.org.debian:01:e45a7fa9d6ec InitiatorName=iqn.1993-08.org.debian:01:cf88d296de8d InitiatorName=iqn.1993-08.org.debian:01:51de7eb4a092

If you can't or get an error, it's prob an ssh key issue. From the affected node do:
ssh -i /etc/pve/priv/zfs/192.168.8.187_id_rsa root@192.168.8.187
