Partitioning Schemes

Small root, large /a with LVM

Partman recipe es.cfg

Partition layout:

• 10-40G for /
• 8G for swap
• the rest for /a with LVM

This layout is used on:

• databases

Variants:

• in hosts with 1 disk
  • no change.
• in hosts with 2 disks
  • make / software RAID1
  • put a swap partition on both disks
  • make /a software RAID1, load LVM on top of that
• in hosts with more than 2 disks (12, 48, etc.) and hardware RAID
  • configure all the disks in one RAID10 array
  • configure as with 1 disk

Small root, large /a all LVM, separate /boot

Partman recipe lvm-noraid-large.a.cfg

Partition layout:

• 300M for /boot
• the rest for LVM with 3 volumes:
  • 40G for /
  • 8G for swap
  • the rest for /a

This layout is used on:

Variants:

Large root, separate /tmp

Partman profile mw.cfg

Partition layout:

• 70% of the disk for /
• 8G swap
• 20% for /tmp

This layout is used on:

• mw hosts

Variants:

Large root, nothing else

• Partman profile is raid1-1T-1partition.cfg

Partition layout:

• 99% of the disk for /
• 8G swap

This layout is used on:

• msfe hosts

Variants:

• on hosts with 2 1T disks
  • RAID1 on /
  • one 4G swap partition on each disk

Small root, remaining raw disks

Partition layout:

• 10-40G for /
• 8G swap
• everything else raw disks mounted in /mnt

This layout is used on:

• swift storage bricks

Variants:

• on ES hosts (12 disks, hardware RAID)
  • 2 disks RAID1 for /
  • 10 disks with 1 partition each formatted xfs mounted in /mnt/

Filesystems

• Use ext3 for /
• Use xfs for /a
