Max Stripe Unit Size in LVM/HP-UX 11.00

[John Thykattil]

I remember from my hands on lvm class that the max for the -I flag in lvcreate was only 64k, eventhough the man page states 32MB. Does anyone know the real answer? I am running HP-UX 11.00 on V-class. Thanks.

Man page is wrong. You can create a stripe size of upto the extent size.

Hi John,

The answer is 32MB !

For 11.0, there is a cumulative path - PHCO_24437 (LVM Commands cumulative patch). This will change the current maximum stripe size from 64K to 32MB.

I read the man page wrong!!!.. :-). While the max limit is 32MB, you can only create the stripe size less than equal to the extent size.
