  50. 50. 08 ZFS on Amazon EC2 How to install and run ZFS on Amazon EC2 (yes, you can!) Thanks to: Constantin Gonzalez Dougal Ballantyne (demo coming soon) 50
  51. 51. What is ZFS? ZFS is a file system + logical volume manager. Features: - protection against data corruption - support for high storage capacities - integration of filesystem and volume management - snapshots and copy-on-write clones - continuous integrity checking and automatic repair - RAID-Z - native NFSv4 ACLs. OpenZFS is an Open Source implementation of it. 51
  52. 52. How can I use it? Launch an EC2 instance with an AMI which supports ZFS. 1) Linux 2) OmniOS (native ZFS support based on a fork of the original OpenSolaris project that open-sourced ZFS) 3) FreeBSD (native ZFS support based on a port of the OpenSolaris ZFS code) 52
  53. 53. 1) Linux Linux AMI: https://aws.amazon.com/amazon-linux-ami/ http://zfsonlinux.org/ 53
  54. 54. 2) OmniOS 54
  55. 55. 3) FreeBSD 55
  56. 56. And now what? It works the same as with any other hardware platform: 1) Attach a few EBS volumes to your EC2 instance; 2) use them as you would use regular disks with ZFS An example follows. 56
  57. 57. $ sudo modprobe zfs [attach 3 EBS volumes to the instance] $ sudo zpool create test raidz sdf sdg sdh $ sudo zpool status pool: test state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM test ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 sdf ONLINE 0 0 0 sdg ONLINE 0 0 0 sdh ONLINE 0 0 0 errors: No known data errors 57
  58. 58. $ mount /dev/xvda1 on / type ext4 (rw,noatime) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) test on /test type zfs (rw,xattr) $ df -h Filesystem Size Used Avail Use% Mounted on /dev/xvda1 7.9G 1.6G 6.3G 20% / tmpfs 15G 0 15G 0% /dev/shm test 196G 0 196G 0% /test 58
  59. 59. What can I do with ZFS? Many things! Here’s one example: Use an EBS Provisioned IOPS volumes as ZFS cache and log (ZIL) devices to accelerate your zpools. This works much like you would use SSDs in the real world to accelerate ZFS reads and writes. For instance, you could provision an EBS volume with 1000 IOPS and use it as a ZIL device for your zpool in order to accelerate database writes. 59
