VDEV

Virtual Devices

• Not physical disks
• Logical groupings of
• Backbone of a ZPool
• Can be a single disk
  • Or multiple disks
    • Mirrors
    • RAID-Z

Striped

RAID-0

• Stripes data across all the drives
• No fault tolerance

sudo zpool create new-pool /dev/sdb /dev/sdc

Mirrored

RAID-1

• Survives failure of 1 drive (for mirror of 2 drives)

sudo zpool create new-pool mirror /dev/sdb /dev/sdc

# -m for mountpoint
sudo zpool create -m /usr/share/pool new-pool mirror /dev/sdb /dev/sdc

RAID-Z

• Data redundancy and protection
• RAID-Z[1/2/3]
  • Levels of parity
  • Disks that can fail

sudo zpool create myraidzpool raidz1 /dev/ada1 /dev/ada2 /dev/ada3 /dev/ada4

Detach

• Detach a mirrored device

sudo zpool detach zeepool c2t1d0
