Issue

  • Aggregate auto-provision command fails with the following error:
Error: Provisioning "Cluster_1_01_aggr_1" failed. Reason: [Job 452] Job failed: Failed to create aggregate "Cluster_1_01_aggr_1" on "Cluster-1-01". Reason: There are not enough spare disks with matching RPM. 11 disks needed from one pool, but not enough matching disks of the requested size are available in either pool.
 
  • Example:
Cluster-1::> aggr auto-provision -verbose
Per node summary of new aggregates to create, discovered spares, and also
remaining spare disks and partitions after aggregate creation:

New    Total New -Discovered Spare- -Remaining Spare-
Node               Aggrs  Usable Size  Disks  Partitions  Disks Partitions
------------------ ----- ------------ ------ ----------- ------ ----------
Cluster-1-01           1      13.05TB      0          12      0          1
Cluster-1-02           1      13.05TB      0          12      0          1
------------------ ----- ------------ ------ ----------- ------ ----------

New data aggregates to create with counts of
disks and partitions to be used:

RAID group layout showing how spare disks and partitions will be used
in new data aggregates to be created:

RAID Group In New                      Disk       Usable Disk Or   ---Count---
Data Aggregate To Be Created           Type         Size Partition Data Parity
-------------------------------------- ------ ---------- --------- ---- ------
/Cluster_1_01_aggr_1/plex0/rg0          SAS        1.61TB partition    9      2
/Cluster_1_02_aggr_1/plex0/rg0          SAS        1.61TB partition    9      2

Details about spare disks and partitions remaining after aggregate creation:

------------------ ------ ------------ --------- ---------
Cluster-1-01       SAS          1.61TB partition         1
Cluster-1-02       SAS          1.61TB partition         1
