Re: Change block size.

Shalom,

You an surely change it with the newfs or the mkfs command.

But it won't help oracle performance a bit.

Re: Change block size.

Hi ,

These are the steps for changing the block size

1)Take the backup of FS using vxdump
2)unmount the FS
3)change the fragment size
4)mount FS
5)do the restoration of backup using vxrestore
For success, attitude is equally as important as ability
