maxvol keyword

Postby jaggz » Thu May 16, 2013 4:37 pm

Hello,

I am trying to define a ZFS with a dynamic Count value of 5 using batch. I understand maxvol Keyword helps in defining but I am not sure what utility would accomodate the keyword maxvol while defining.

Any suggestions or advise would be really great.

Are you sure you are on the correct website? ZFS is a combined file system and logical volume manager designed by SUN Microsystems. This is an IBM website.
We know that the features of the Zettabyte File System ZFS include protection against data corruption, support for high storage capacities, integration of the concepts of filesystem and volume management, snapshots and copy-on-write clones, continuous integrity checking and automatic repair, RAID-Z and native NFSv4 ACLs.
And although ZFS can be implemented as open-source software, it is still a product of Oracle.
As a suggestion you might want to read the Oracle manuals

pmartyn, zFS is short for z/OS Distributed File Service (DFS) zSeries File System (zFS), which is the replacement file system for HFS in Unix System Services on z/OS systems. See http://www.redbooks.ibm.com/redbooks/pdfs/sg246580.pdf for details.

jaggz, your best bet would be to reference whatever material mentioned maxvol and use it. I've defined and grown plenty of zFS file systems over the years (some up over 40 GB total space) using IOEAGFMT, and the parameters are typically in MB not volumes. As long as the storage group has available volumes with available free space, zFS will convert the space request to cylinders. I've never heard of "maxvol" as a parameter, which is why I recommend you go back to wherever you got that information from.
