OmniOS

Howto: https://napp-it.org/downloads/omnios.html

See also Shared Storage System Notes.

See also napp-it.

See also ZFS.

:!: For large-memory systems, choose a larger boot drive or disable dump because the swap and dump devices take up a lot of space by default.

Memory

echo ::memstat | mdb -k
swap -lh

Install Pkg File

pkgadd -d package_name.pkg

Full Reboot

A normal 'reboot' command does a fast reboot. This does a full reboot:

reboot -p

:!: The following commands change the default behavior of the reboot command to do a full reboot not a fast reboot.

svccfg -s "system/boot-config:default" setprop config/fastreboot_default=false
svccfg -s "system/boot-config:default" setprop config/fastreboot_onpanic=false
svcadm refresh svc:system/boot-config:default

Updating

Update the 'pkg' package manager first:

pkg install pkg:/package/pkg

You can then do a trial run image update:

pkg image-update -nv

Run the same command again without the 'n' flag to actually do the update.

Upgrading

Manage Boot Environments

http://docs.oracle.com/cd/E23824_01/html/E21801/administer.html

beadm list                                    # list BE's
beadm rename <be-name> <new-be-name>          # rename a BE - can't rename active BE
beadm destroy <be-name>                       # delete a BE
beadm activate <be-name>                      # make another BE active on reboot

Installing

http://omnios.omniti.com/wiki.php/Installation

If you are using SATA interfaces on the server mainboard, configure the BIOS to AHCI mode before installing OmniOS. If you forget, you will have to reinstall to fix this.

Download the CD image and burn it to a disc or download a USB image and burn it to a flash drive:

dd if=/path/to/image.usb-dd of=/dev/sdx bs=1M

Adjust Boot (GRUB) Timeout

bootadm set-menu timeout=5

Permit Root Login

:!: The system installs a root user with a blank password.

Set the root password with the passwd command.

Enable root login via ssh in the Napp-IT web interface: Services > SSH allow root

or by editing the /etc/ssh/sshd_config file, changing the PermitRootLogin option to yes.

Networking

http://docs.oracle.com/cd/E19963-01/html/821-1458/gkind.html

New tools supersede the older ipconfig and ndd tools:

  • dladm
  • ipadm
  • Changes persist after reboot

Useful networking commands (examples below):

dladm show-phys
dladm show-link
ipadm show-if [interface]
ipadm show-addr [addrobj]
ipadm create-addr -T address-type -a address/prefixlen addrobj
ipadm show-addrprop [-p property] [addrobj]

Basic Network Configuration

http://docs.oracle.com/cd/E23824_01/html/821-1458/gljtt.html

dladm show-phys                                        # list available interfaces
dladm show-link                                        # shows link status
dladm show-ether                                       # shows Ethernet info
dladm show-aggr                                        # shows aggregated interfaces
ipadm show-addr                                        # show IP addressing
netstat -nr                                            # show IP routes

Static

Disable nwam (Network AutoMagic):

svcs nwam
svcs network/physical:default

svcadm disable svc:/network/physical:nwam
svcadm enable svc:/network/physical:default

Delete an IP interface before configuring it, if it already exists:

ipadm show-if
ipadm delete-if igb0
ipadm create-if igb0
ipadm create-addr -T static -a 192.168.1.4/24 igb0/v4  # assign an IPv4 address
route -p add default 192.168.1.1                       # assign a default route if not already configured

DHCP

ipadm create-addr -T dhcp igb0/dhcp

Name Resolution

:!: Use your domain name and your internal DNS server.

echo 'domain domainname.tld' > /etc/resolv.conf
echo 'nameserver 10.0.0.5' >> /etc/resolv.conf
echo 'nameserver 8.8.8.8' >> /etc/resolv.conf
cp /etc/nsswitch.dns /etc/nsswitch.conf

SSH

vi /etc/ssh/sshd_config

PermitRootLogin yes
GSSAPIAuthenication no                    # Fix slow logins
AllowUsers root backupuser                # If you need another user to use SSH
svcadm restart svc:/network/ssh:default

See also UNIX Link Aggreagation (Bonding)

  • Napp-IT (free) doesn't do bonding
  • Use the CLI

Jumbo Frames

vi /kernel/drv/ixgbe.conf

default_mtu             = 9000;

Storage

Install LSI SAS2IRCU

:!: Needed for LSI HBAs

Download the SAS2IRCU archive from Broadcom and upload it to the desired server.

https://www.broadcom.com/support/download-search?pg=&pf=&pn=&pa=&po=&dk=sas2ircu

chmod +x sas2ircu
./sas2ircu list
./sas2ircu 0 display

Install LSI MegaCLI

:!: Only works with RAID controllers, not HBAs.

Download the MegaCLI archive from Broadcom and upload it to the desired server.

https://www.broadcom.com/support/download-search?pg=&pf=&pn=&pa=&po=&dk=megacli

pkgadd -d MegaCli.pkg

chmod +x /opt/MegaRAID/CLI/MegaCli
/opt/MegaRAID/CLI/MegaCli

Mirror the Boot Drive

FIXME This section is a mix of old and new information. It needs editing.

See also Napp-IT ZFS Storage Server

Read the help first in Napp-IT → Home → Disks → Mirror Bootdisk

List all disks and ZFS pools:

echo |format
zpool list
cfgadm -s "select=type(disk)"
zpool status rpool
  • p0 is entire disk
  • s0 is first slice

Create one large partition:

If there is any preexisting configuration on the disk (many drives come partitioned!), such as partition info, reinitialize it with Napp-IT → Home → Disks → Initialize

FIXME Is the following necessary?

Set up SMI label with same partitioning as original boot disk:

pfexec prtvtoc /dev/rdsk/c5t2d0s2 | pfexec fmthard -s - /dev/rdsk/c5t3d0s2

Add the second drive to the rpool:

pfexec zpool attach -f rpool c5t2d0s0 c5t3d0s0

If your bootdisk ends with s0 (ex c0t0d0s0), s0 is added to newdisk like: zpool attach -f rpool c0t0d0s0 c0t1d0s0.

:!: Do not continue until the resilver is finished.

Check resilver progress:

zpool status -v rpool

Make the mirror drive bootable:

bootadm  install-bootloader -Mfv -P rpool

:!: To boot to the second drive, select it in the BIOS as the first boot device.

reboot -p

Package Management

Configure Publishers (Repositories)

pkg publisher                                                        # list configured publishers
pkg set-publisher -g http://pkg.omniti.com/omniti-ms/ ms.omniti.com  # add a publisher
pkg unset-publisher ms.omniti.com                                    # remove a publisher

Managing Dump and Swap

Dump

:!: You only need a dump device if you need (and usually buy) help from OS devs, example from OmniTi. If so, you may need a larger rpool commensurate with your server's RAM size.

Estimate needed dump space (128GB RAM):

root@stor-01:/root# dumpadm -e
Estimated dump size: 61.5G

Query the current dump device size:

root@stor-01:/root# zfs get volsize rpool/dump
NAME        PROPERTY  VALUE    SOURCE
rpool/dump  volsize   17.7G    local

Change the dump volume size:

zfs get volsize rpool/dump

zfs set volsize=4G rpool/dump

Disable dump and delete the dump volume:

dumpadm -d none
zfs destroy rpool/dump

Swap

:!: You can probably skip this section if you are configuring a storage server as the swap space is not pre-allocated.

Note the change in blocks allocated to swap:

swap -lh
swap -d /dev/zvol/dsk/rpool/swap
zfs volsize=4G rpool/swap
swap -a /dev/zvol/dsk/rpool/swap
swap -lh

User Management

Add User

useradd -g staff -d /home/newuser -m -s /bin/bash -c "Full Name" newuser

Make 'newuser' an administrator (sudo privileges):

visudo

Check for errors:

pwck

User Roles (RBAC)

https://blogs.oracle.com/observatory/en_US/entry/understading_rbac

Allow 'newuser' to 'su' to 'root':

usermod -R root newuser

Services (Daemons)

List services:

svcs

After making configuration file changes:

svcadm refresh <servicename>

:!: If services show as 'maintenance' rather than 'online', there is probably a configuration error.

FTP

https://www.napp-it.org/extensions/proftpd.html

Install ProFTPd:

wget -O - www.napp-it.org/proftpd | perl

This starts the service and can also be used to restart the ProFTPd service after making configuration changes:

Services → FTP → Enable proftpd

svcs proftpd
svcadm enable proftpd
svcadm disable proftpd

FIXME So far, I have only used manual methods for controlling users, home directories and permissions!

NTP

Configure NTP:

vi /etc/inet/ntp.conf

Edit:

pool 0.us.pool.ntp.org iburst
pool 1.us.pool.ntp.org
pool 2.us.pool.ntp.org
pool 3.us.pool.ntp.org

Set the time and enable the NTP daemon:

ntpdate pool.ntp.org

svcadm enable ntp

NTP takes a while to get synchronized. Check the status (on localhost) like this:

ntpq -p

IPMI

pkg install ipmi ipmitool

Legacy Info Below

Add Unrecognized New Hardware

:!: While this section was written for the new Intel x540 10GbE NIC, it seems this driver has been updated and these steps are no longer necessary. These notes are left as an example only.

Determine the 'vendor' and 'device' id's that aren't being recognized by the 'ixgbe' driver, then add them to the list:

scanpci

grep ixgbe /etc/driver_aliases

update_drv -a -i "pci8086,1528" ixgbe

ifconfig -a plumb
ifconfig -a

modinfo|grep ixgbe

more /etc/path_to_inst | grep ixgbe

Add New Persistent NIC

:!: If you are using Napp-IT, use it for assigning IP addresses.

vi /etc/hostname.ixgbe0
10.1.10.5 netmask 255.255.255.0
vi /etc/hostname.ixgbe1
10.1.10.6 netmask 255.255.255.0
vi /etc/inet/hosts
10.1.10.5       10g-eth-1 
10.1.10.6       10g-eth-2

Configure Jumbo Frames

Intel X540 10GbE NIC

http://docs.oracle.com/cd/E19254-01/820-7895-11/cggfhffg.html
