When a disk is added to a VG it is divided in parts the size of PPsize.

So you can tell by applying LVM restrictions: a single disk can hold max. 1019 PPs. If you have disks approximately 32GB in size you can go with a PP size of 32MB, arriving at ~1000 PPs per disk. If your disks are considerably larger than this you would only be able to use the first 32GB (1019x32MB to be exact) of the disk, losing the rest of it.

Since it is a good idea of leaving room for expansion everywhere consider using a PP size which divides the disk in 200-500 parts. For example: for 72GB disks use a PP size of 256MB giving ~300 PPs. This would allow for the use of disks up to 260GB without losing space.

I hope this helps.

IPTABLES-RESTORE(8)                                               iptables 1.6.1                                               IPTABLES-RESTORE(8)

NAME

       iptables-restore -- Restore IP Tables

       ip6tables-restore -- Restore IPv6 Tables

SYNOPSIS

       iptables-restore [-chntv] [-M modprobe] [-T name] [file]

       ip6tables-restore [-chntv] [-M modprobe] [-T name] [file]

DESCRIPTION

       iptables-restore  and ip6tables-restore are used to restore IP and IPv6 Tables from data specified on STDIN or in file. Use I/O redirection
       provided by your shell to read from a file or specify file as an argument.

       -c, --counters
              restore the values of all packet and byte counters

       -h, --help
              Print a short option summary.

       -n, --noflush
              don't flush the previous contents of the table. If not specified, both commands flush (delete) all previous contents of the  respec-
              tive table.

       -t, --test
              Only parse and construct the ruleset, but do not commit it.

       -v, --verbose
              Print additional debug info during ruleset processing.

       -M, --modprobe modprobe_program
              Specify  the path to the modprobe program. By default, iptables-restore will inspect /proc/sys/kernel/modprobe to determine the exe-
              cutable's path.

       -T, --table name
              Restore only the named table even if the input stream contains other ones.
