This article describes the booting process of SME Server.
Installation
When booting from the installation CD you will get a boot prompt where you can simply press Enter to start the standard installation (or upgrade) routine. On i586 (e.g. VIA C3) based machines type smei586 and press Enter.
After showing the boot prompt for some time SME will start the installation process automatically. It will then afford you the opportunity to test the installation medium.
Afterwards you can choose which language you want to use for the following installation process.
Boot Options
You can use the function keys F1 to F5 to get more information about different boot options.
Installer Boot Options
Normal installation
sme
Set raid type
sme raid=[none,0,1,5,6]
Set number of spares
In case you have 3 or more hard disks in your server and don't want to have a spare disk
sme spares=[0-(disks-2)]
Set drive type to include
Nominate which drives the installer will use to put the OS onto, not nominating a drive will exclude it from use, if left blank will include all drives
sme drives=[hda,sda,xvda,...]
Set drives to exclude
Nominate which drives the installer will not try to install the OS to eg a boot USB with the iso on it, or other connected backup USB drives, see note below
sme exclude= sdc
To install SME without software RAID
For example MB with fake raid or with 'Config Disk' issue bugzilla:5850
sme raid=0
To install SME without a logical volume manager type
sme nolvm
To have /, /tmp, /var, /home/e-smith/files and swap on separate partitions type
sme multipart
If you have a driver disk type
sme dd
Installation hangs
The last screen shown is "Welcome to SME Server".
sme ide=nodma
Installation errors when disks previously used with fake raid.
sme ide=nodmraid
SATA Driver installation error
eg IBM IntelliStation M Pro stalls
sme acpi=off
Intel DG965 Motherboards (G33xx)
sme pci=nommconf acpi=off all-generic-ide
To enable the rescue mode type
sme rescue
To use an ext4 file system
(except for /boot) instead of the default ext3.
sme ext4
Notes
The installer without anything being passed should behave identically for disks < 10 with the exception that it won't include any device that is housed on a drive that needs the usb-storage or spb2 module.
If you want to include drives that are on USB or firewire you must use the drives= option and specify all drives (not just the usb/firewire drives) that you want to use.
If you don't want to use raid at all specify raid=0 or raid=none (they are identical, 0 means none).
If you don't want a spare you should use the spares= option and specify a value of 0. By default 1 spare will be added for disks > 3. Another spare drive will be added for every additional 7 drives you add (10, 17, ...).
If you specify a raid level but don't have enough drives it will fall back to the next highest raid level (ex. 5 drives, 2 spares, raid 6 will fail back to raid 5 as 5-2=3 useable drives).
From SME ISO releases 7.5.1 and SME 8.0beta6 the installer will automatically exclude the drive containing the install media or ks files. Refer http://forums.contribs.org/index.php/topic,46866.msg230681.html#msg230681
General Boot Help
Certain hardware configurations may have trouble with the automatic hardware detection done during the installation. If you experience problems during the installation, restart the installation adding the noprobe option. With the standard installation that would be
sme noprobe
or e.g. if you don't want a software RAID:
sme noraid noprobe
and so on.
Kernel Parameter Help
Some kernel parameters can be specified on the command line and will be passed to the kernel. This does not include options to modules such as ethernet cards or devices such as CD-ROM drives.
To pass an option to the kernel use the following format:
sme <options>
If a different installation mode is desired, enter it after the option(s).
For example, to install on a system with 128MB of RAM using noprobe mode, type the following:
sme mem=128M noprobe
To pass options to modules, you will need to use the noprobe mode to disable PCI autoprobing. When the installer asks for your device type that needs an option or parameter passed to it, there will be a place to type those in at that time.
Rescue Mode Help
The installer includes a rescue mode which can be used when a system does not boot properly. The rescue mode includes many useful utilities (editor, hard drive and RAID tools, etc.) which will allow one to restore a system to a working state.
To enter the rescue mode, boot your system from the installation CD-ROM and type:
sme rescue
To actually be able to edit files, remount the root partition by typing:
mount -n -o remount /

Some problems with booting that cannot or will not be fixed through development of SME7 and solutions how to bypass them can be found here.
You can run Memtest86 to check your RAM by typing
memtest
at the boot prompt and pressing Enter afterwards.
