Fail to alter E-Series volume segment size

Last Updated:

Applies to

  • E-Series
  • Volume Group


The process of changing the segment size in the following sequence fails:
  1. Creating a new volume with a segment size of 8K.
  2. Increasing the segment size from 8K to 16K.
  3. Encountering an error when attempting to increase the segment size from 16K to 32K.
 The operation cannot complete for one of the following reasons:
    (1) The requested segment size is not valid,
    (2) The requested segment size is not allowed because it is more than twice or less than half the current segment size,
    (3) The requested segment size is not allowed because this volume has an odd number of segments, or
    (4) The segment size specified is not valid for the current cache block size.
 If case (3) applies, you may only decrease the segment size for this volume to a smaller number. (API 40)
