Hello,

i am just trying to understanding the methods adopted for resizing a ZFS dataset. The way I am thinking is about creating a new ZFS with larger allocation and do a repro from a old ZFS. Then Update the BPXPRMxxx if required and with an IPL.

Could someone shed light on the above.

I have successfully used OMVS command zfsadm grow for resizing zFS file systems. The advantage is there's no need to copy anything, but the disadvantage is that the aggregate will be placed in Quiesce status while the grow command is underway. However, this is usually not a very long period of time and hence there is not usually a major impact. Also, there is no need to update BPXPRMxx since the aggregate name doesn't change.
