Defines the disk layout for the installation. Specify a comma-separated list of partition definitions using: mountpoint=size[:filesystem][:drivenumber]
- mountpoint — Target mount location (e.g.,
/, /var, /data). Use none to create an unformatted partition.
- size — Either a size in megabytes (e.g.,
102400), a percentage of total disk space (e.g., 50%), or rest to consume remaining space.
- filesystem (optional) — Defaults to
ext3 (ext2 for /boot) if omitted. Supported filesystems include ext2, ext3, ext4, xfs, and jfs. Use none for unformatted partitions.
- drivenumber (optional) — Target disk number (e.g.,
1, 2). Starts at disk 1. If omitted, the primary disk is used.
Examples
- One Drive Partitions String:
/=102400,/var=204800,/data=rest
- Drive 1 has a 100GB root (/) partition, a 200GB /var partition, and a /data partition using the remainder of the space on the drive, all with ext3 formatting
- Multiple Drives Partitions String:
/=102400:ext4:1,/var=204800:ext4:1,/data=rest:ext4:1,/backup=rest:xfs:2,/tmp=102400:ext4:3,none=rest:none:3
- Drive 1 has a 100GB root (/) partition, a 200GB /var partition, and a /data partition using the remainder of the space on the drive, all with ext4 formatting
- Drive 2 has a single /backup partition formatted in XFS using the entire drive
- Drive 3 has a /tmp partition using 100GB formatted in ext4, with the remainder of the space on the drive in an unformatted partition
Software RAID can be configured using the partitions string with the following format: raid=size:raidlevel:drivenumber,raid=size:raidlevel:drivenumber,mountpoint=rest[:filesystem]:raid
- size — Functions as before, with
rest being the recommended value to consume the full drive for RAID usage
- drivenumber — Functions as before and is used to indicate which drives are participating in the RAID
- raidlevel — The requested RAID level. Supported are
1 (mirroring) and 0 (striping)
- mountpoint — Functions as before, except that
raid is used instead of drive number for any partitions intended for the RAID
Examples
- RAID 1 partitions string:
raid=rest:1:1,raid=rest:1:2,/=102400:ext4:raid,/data=rest:xfs:raid
- RAID 1 has both drives allocated fully with a 100GB root (/) partition formatted with ext4 and the remainder in the
/data partition formatted with XFS
- RAID 0 partitions string:
raid=rest:0:1,raid=rest:0:2,/=102400:ext4:raid,/data=rest:xfs:raid
- RAID 0 has both drives striped with a 100GB root (/) partition formatted with ext4 and the remainder in the
/data partition formatted with XFS
