Revision as of 11:29, 24 August 2024
This is the build about the hypervisor in 2024.
This is a 1 RU server with fast local SSD, aprox 18TB of storage.
Bios settings
A patched bios is needed for this to boot of UEFI and also enable PCI hotplug menu in the bios. I was able to edit this and have posted the latest version here.

Creating new GPT entries in memory.
Command (? for help): n
Partition number (1-128, default 1): 1
First sector (6-390624994, default = 256) or {+-}size{KMGTP}: 2048
Last sector (2048-390624994, default = 390624767) or {+-}size{KMGTP}: +384G
Current type is 8300 (Linux filesystem)
Hex code or GUID (L to show codes, Enter = 8300): BF01
Changed type of partition to 'Solaris /usr & Mac ZFS'

Partition table holds up to 128 entries
Main partition table begins at sector 2 and ends at sector 5
First usable sector is 6, last usable sector is 390624994
Partitions will be aligned on 256-sector boundaries
Total free space is 289961693 sectors (1.1 TiB)

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!
Do you want to proceed? (Y/N): y
OK; writing new GUID partition table (GPT) to /dev/nvme0n1.
The operation has completed successfully.
create the pool
Note that due to slot 8 and 9 being on their own 2 ports of 8 they will run faster than the rest and fill unequally if paired together.
zpool create -f -o ashift=12 -O compression=lz4 -O atime=off -O xattr=sa localDataStore \ mirror /dev/disk/by-enclosure-slot/front-slot000 /dev/disk/by-enclosure-slot/front-slot001 \ mirror /dev/disk/by-enclosure-slot/front-slot002 /dev/disk/by-enclosure-slot/front-slot003 \ mirror /dev/disk/by-enclosure-slot/front-slot004 /dev/disk/by-enclosure-slot/front-slot005 \ mirror /dev/disk/by-enclosure-slot/front-slot006 /dev/disk/by-enclosure-slot/front-slot008 \ mirror /dev/disk/by-enclosure-slot/front-slot007 /dev/disk/by-enclosure-slot/front-slot009 \ special mirror /dev/disk/by-enclosure-slot/nvme-upper-2-part1 /dev/disk/by-enclosure-slot/nvme-lower-0-part1
Backplane
The onboard backplane is a BPN-SAS3-116A-N2 which has 8 SAS disks and then 2 NVME or SAS. Howerver this last thing is not true if you want to run 10 SAS disks. The right most NVME/SAS ports are called "SAS2" ports on the backplane, but are really SATA ports, and connected to the onboard SATA. As this is a backplane only, not an expander each physical SAS port from the controller is connected to one SAS drive. Since the included controller only had 8 ports, a 16 port controller is used.
NVME name spaces
https://narasimhan-v.github.io/2020/06/12/Managing-NVMe-Namespaces.html
The NVME come setup as 1.88T disks:
tnvmcap : 1,880,375,648,256 unvmcap : 375,648,256
I suspect this is a 2.0 TiB (2,199,023,255,552b) provisioned down in the controller or about 85%. moving this to a 1.6TB disk will under provision this and make it perform better in the event we use it as log or write intensive.
Ensure we're on 4096 bytes
nvme id-ns -H /dev/nvme0n1 | grep "LBA Format" nvme id-ns -H /dev/nvme1n1 | grep "LBA Format" nvme id-ns -H /dev/nvme2n1 | grep "LBA Format" nvme id-ns -H /dev/nvme3n1 | grep "LBA Format"
1 & 2 Detatch the name space
nvme detach-ns /dev/nvme1 -namespace-id=1 -controllers=4 nvme detach-ns /dev/nvme3 -namespace-id=1 -controllers=4 nvme detach-ns /dev/nvme2 -namespace-id=1 -controllers=4 nvme detach-ns /dev/nvme0 -namespace-id=1 -controllers=4
Delete the namespace
nvme delete-ns /dev/nvme1 -namespace-id=1 nvme delete-ns /dev/nvme3 -namespace-id=1 nvme delete-ns /dev/nvme2 -namespace-id=1 nvme delete-ns /dev/nvme0 -namespace-id=1
Make the new namespace
nvme create-ns /dev/nvme1 --nsze-si=1.6T --ncap-si=1.6T --flbas=0 --dps=0 --nmic=0 nvme create-ns /dev/nvme3 --nsze-si=1.6T --ncap-si=1.6T --flbas=0 --dps=0 --nmic=0 nvme create-ns /dev/nvme2 --nsze-si=1.6T --ncap-si=1.6T --flbas=0 --dps=0 --nmic=0 nvme create-ns /dev/nvme0 --nsze-si=1.6T --ncap-si=1.6T --flbas=0 --dps=0 --nmic=0
Attach the namespace to the controller
nvme attach-ns /dev/nvme1 --namespace-id=1 --controllers=4 nvme attach-ns /dev/nvme3 --namespace-id=1 --controllers=4 nvme attach-ns /dev/nvme2 --namespace-id=1 --controllers=4 nvme attach-ns /dev/nvme0 --namespace-id=1 --controllers=4
reset the controller to make it visable to the OS
nvme reset /dev/nvme1 nvme reset /dev/nvme3 nvme reset /dev/nvme2 nvme reset /dev/nvme0
Confirm it

hostname
echo Fink >/etc/hostname
- Edit the /etc/hosts

- Reboot
snmp
- Install SNMP
sudo apt-get -y install snmp snmpd libsnmp-dev
- Stop the snmpd service so we can add a user
sudo service snmpd stop
- Add a SNMPv3 user:
sudo net-snmp-config --create-snmpv3-user -ro -A AuthPassword -a MD5 -x AES privUser sudo net-snmp-config --create-snmpv3-user -ro -A keeklespasswd -a MD5 -x AES KeeklesSNMP
- copy the /etc/snmp/snmpd.conf from eyes to the subject server
scp /etc/snmp/snmpd.conf bryan@p25hub.w9cr.net:/home/bryan mv /home/bryan/snmpd.conf /etc/snmp/snmpd.conf
- edit the /etc/snmp/snmpd.conf
vim /etc/snmp/snmpd.conf Update the syslocation and such
- restart snmpd
service snmpd start
- Test SNMP
# TEST snmpwalk -v3 -u KeeklesSNMP -l authNoPriv -a MD5 -A keeklespasswd 127.0.0.1
observium client
export SERVER=<hostname>
- on target server:
sudo apt-get install snmpd php perl curl xinetd snmp libsnmp-dev libwww-perl #only needed for postfix apt-get -y install rrdtool mailgraph dpkg-reconfigure mailgraph
- install the current distro program on the target:
sudo curl -o /usr/local/bin/distro https://gitlab.com/observium/distroscript/raw/master/distro sudo chmod +x /usr/local/bin/distro
- From eyes

- Edit /etc/xinetd.d/observium_agent_xinetd so the Observium server is allowed to connect. You can do this by substituting 127.0.0.1, or place your IP after it, separated by a space. Make sure to restart xinetd afterwards so the configuration file is read.
sudo service xinetd restart
- Test from eyes

default editor
update-alternatives --config editor Then select #3 vim.basic

sudo timedatectl set-timezone UTC
sudo config
add local user accounts
useradd -D -s /bin/bash -m -U -G sudo bryan
- copy over ssh
rsync -avz /home/bryan/.ssh root@192.168.8.186:/home/bryan/
Configure sudo
echo "bryan ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers.d/00-admins
Configure Postfix
Postfix is installed to forward mail for root to a smtp host.
apt-get install postfix mailutils
This will run an installer with a curses interface and you must select Satallite System. Check the System mail name is the hostname of the server, and the SMTP relay host is morty.keekles.org. Root and postmaster mail should be rootmail@allstarlink.org.
Should you need to reconfigure this use:
dpkg-reconfigure postfix
other aliases are setup in /etc/aliases. You must run newaliases after this is updated for them to take effect.
Network
NIC
The MLX4 2x40g nic needs some setting in it's module to set to ethernet and not infaband mode.
echo "options mlx4_core port_type_array=2,2" >/etc/modprobe.d/mlx4.conf
now to setup the mapping of port to mac for the qe0 and qe1 interfaces
echo -e \
'SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{dev_id}=="0x0", ATTR{type}=="1", ATTR{address}=="00:02:c9:37:bc:80", NAME="qe0"'"\n"\
'SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{dev_id}=="0x0", ATTR{type}=="1", ATTR{address}=="00:02:c9:37:bc:81", NAME="qe1"' \
>/etc/udev/rules.d/70-persistent-net.rules
/etc/network/interfaces
Setup this based on the other servers
/etc/network/if-up.d/00-keekles.sh
copy this file to the server for others.
/etc/pve/localfirewall.sh
Copy this from the other servers. this probally is not needed as once it joins the cluster it should appear there.
domain names
Edit this in the dns to set it up
