rsync from partition to partition fastest
Gentleman,
Please move if I have chose the incorrect forum section. I am trying to move data that is not backed up from partition 1 to partition 2 on a SAN that has a GFS2 filesystem. Since the data is not backed up I am rsyncing this data and once verified I will delete from the source partition.

The command that I am using is painfully slow. However this is the way that I was taught to use the rsync command and I am having trouble sorting out the options from the man page.

Can someone please recommend a better or faster command set?

Here is the command I am currently using.

Code:
[rubedo@NYOTS01 ~]$ /usr/bin/rsync  -rlvtzgoD /mnt/onetick2/data/taq_nbbo/ /mnt/onetick1/databases/

At the rate that I am currently syncing it will take days to copy the 2TB's that I am trying to move.

partitio

PARTITION(8)						      System Manager's Manual						      PARTITION(8)

NAME

       partition - make a partition table

SYNOPSIS

       partition [-mf] device [type:]size[+*] ...

DESCRIPTION

       Partition  makes  a partition table on device using the types and sizes given.  It may be used in combination with repartition(8) for auto-
       matic installation of Minix.

       You may give up to four type:size[+*] specifications for the partitions.  You may also specify holes before, between, and after the  parti-
       tions.  A hole differs from a partition specification by not having a type.

       The first hole is by default 1 sector to make space for the primary bootstrap and the partition table.  The other holes are 0.

       The  type  field is the type of the partitition in hexadecimal.	The size field is the partition's size in sectors.  The + or * may option-
       ally be added to indicate that the partition must be expanded to contain any leftover space on the device or to mark the partition active.

       Partitions are padded out to cylinder boundaries, except for the first one, it starts on track 1.  Some operating systems care about  this.
       Minix and MS-DOS do not.

OPTIONS

       -m     Minix only, no need to pad partitions.  This is the default for subpartition tables.

       -f     Force making a partition table even if the device is too small.

EXAMPLE

       partition /dev/hd0 01:16384 81:40000 81:2880* 06:20000+

       Partitions  disk 0 into an 8 Mb DOS partition, 20 Mb Minix /usr, 1.44 Mb Minix / (active), and a DOS partition of at least 10 Mb at the end
       of the disk.  (06:0+ would have been ok too, it's just a sanity check.)

SEE ALSO

       hd(4), part(8), repartition(8).
