ZFS (notes)

Device Initialization

GPT

• Clean partition table zap-all device

• Clear all magic strings (mdadm, lvm, partition table, ...) dd if=/dev/zero of=device bs=512 count=2048

• Create fresh GPT sgdisk clear device

• Inform the kernel of the partition change partprobe device

MBR

• Clear partition table dd if=/dev/zero of=device bs=512 count=2048

• Create fresh MBR parted device mktable msdos

Create partitions

GPT but not UEFI (BIOS)

• Create BIOS boot partition (EF02) 2MB
• Create BOOT partition (8300) 512MB ext4

GPT and UEFI

GRUB Bootloader

• Create EFI partition (EF00) 200MB fat32
• Create BOOT partition (8300) 512MB ext4

systemd-boot (aka gummiboot), rEFInd Bootloaders

• Create an unique EFI/BOOT partition (EF00) 512MB fat32

MBR

• Create BOOT partition 512MB ext4

Create ZFS

• Create a SOLARIS type partition with the rest of the disk

• Create zfs pool named antergos

modprobe zfs

zpool create -f -m /install antergos device

• Set the mount point of the root filesystem

zfs set mountpoint=legacy antergos

• Create zfs vol swap

zfs create -V size -b sc_page_size -o primarycache=metadata -o checksum=off -o com.sun:auto-snapshot=false antergos/swap

Example: zfs create -V 524288 -b 4096 -o primarycache=metadata -o checksum=off -o com.sun:auto-snapshot=false antergos/swap

• Set the bootfs property on the descendant root filesystem so the boot loader knows where to find the operating system.

zpool set bootfs=antergos antergos

• Export the pool

zpool export antergos

Does not work (if I wait some time it does, maybe zfs is still working on something at this point?)

zpool export -f antergos

With force always works

• Reimport the pool

zpool import -d /dev/disk/by-id -R /install antergos

• Set the mount point of the filesystem

zfs set mountpoint=/ antergos

• Create zpool.cache file

zpool set cachefile=/etc/zfs/zpool.cache antergos

• Copy created cache file to destination cp /etc/zfs/zpool.cache /install/etc/zfs/zpool.cache
