MySQL Volume Group - PP Size
Hi Friends-

We know that the Max PP size in a Normal VG and Big VG is 1 GB and in case of scalable VG it is 128 G.

My Questions:

1) What is the min PP size allowed for Normal VG, Big VG and Scalable VG?

2) Why is the max PP Size in Normal and Big VG is 1 G and 128 G in scalable VG?


Thanks in advance
Pandith

for scalables the min pp size is 1 mb - I believe 256 k for the others but since your choice depends pretty much on the disk sizes, its not very likely that you choose the very small ones anyway.

scalables support 256 petabyte disks, and can hold up to 2,097,152 (2048 K) PPs. Therefor you need a pp size corresponding to this.

Kind regards
