Adding Cache Devices to an Existing Pool

  1. Install the new Readzilla or Logzilla device into the first available slot. See the Overview in Oracle ZFS Storage Appliance Installation Guide for slot locations.
  2. At the command line, enter:
  3. : poc:> configuration storage
  4. Specify the pool you want to add the device to:
  5. : poc:configuration storage (pool_2)> set pool=pool_2
  6. : pool = pool_2
  7. : poc:configuration storage (pool_2)> add
  8. :A message reminds you to verify that the device is correctly installed. Note that mixing device types and speeds is strongly discouraged.
  9. Show the device information for the pool:
  10. : poc:configuration storage (pool_2) verify> show
  11. : ID STATUS ALLOCATION DATA LOG CACHE RPM
  12. : 0 ok custom 0 0 0/4 1.86T
  13. : 1 ok custom 0 0/2 34G 0 15000
  14. : 2 ok custom 0 0/2 34G 0 15000
  15. Specify which disk shelf and the number of Logzillas or Readzillas to use. In the following example, 1-log=1 allocates one Logzilla from the first disk shelf.
  16. : poc:configuration storage (pool_2) verify> set 1-log=1
  17. : 1-log = 1
  18. :Note: A value of "1-log=2" would allocate two Logzillas from the first disk shelf.
  19. :This example allocates one Readzilla from the first disk shelf.
  20. : poc:configuration storage (pool_2) verify> set 1-cache=1
  21. : 1-cache = 1
  22. Enter done.
  23. : poc:configuration storage (pool_2) verify> done
  24. : Note: If you add an odd number of Logzilla devices to a pool, or if a pool does not have already a profile, enter set log_profile=log_mirror to set the log profile.
  25. Enter show to display the profile.
  26. : poc:configuration storage (pool_2) config> show
  27. :
  28. : PROFILE CAPCTY NSPF DESCRIPTION
  29. : log_profile = log_stripe 17G no Striped log
  30. Enter done to complete the task:
  31. : poc:configuration storage (pool_2) config> done
  32. : poc:configuration storage (pool_2)>
