Issue

  • The proposed partition sizes are displayed correctly in the storage disk create-partition command. Example:

::(star)> storage disk create-partition -source-disk 4.10.20 -target-disk 4.10.23

Warning: Disk "4.10.23" will be partitioned as follows:
                      Usable     Container  Container
        Partition     Size       Type       Name       Owner
        ------------- ---------- ---------- ---------- ----------
        4.10.23.P1    1.69TB     spare      Pool0      node1
        4.10.23.P2    1.69TB     spare      Pool0      node1
        4.10.23.P3    107.7GB    spare      Pool0      node1
{{Do you want to continue? \{y|n}: y
Disk "4.10.23" is now partitioned.
  • However after confirming and having the disk become partitioned, the partitions show incorrect size:

::(star)> storage disk partition show -owner-node-name node1

                          Usable  Container     Container
Partition                 Size    Type          Name              Owner
------------------------- ------- ------------- ----------------- -----------------
...
4.10.23.P1                1.72TB  spare         Pool0             node1
4.10.23.P2                1.72TB  spare         Pool0             node1
4.10.23.P3                61.56GB spare         Pool0             node1
