Top Forums Shell Programming and Scripting rsync from partition to partition fastest Post 302475248 by jaysunn on Saturday 27th of November 2010 12:14:15 PM

@danmero,

Are you suggesting. I use:

Code:
cp -r /path/to/data /path/to/data2

I was worried that the shear amount of data would not work well with cp command.

Note that this is a GFS2 redhat filesystem on 2 separate partitions.
I am getting great speeds now with the rsync - av command.

Not there is no backup for this data so I wish to be as careful as possible.

gfs2_convert(8) 					      System Manager's Manual						   gfs2_convert(8)

NAME
gfs2_convert - Convert a GFS1 filesystem to GFS2 SYNOPSIS
gfs2_convert [OPTION]... DEVICE DESCRIPTION
gfs2_convert is used to convert a filesystem from GFS1 to GFS2. Do not attempt to convert a GFS1 filesystem which is not clean - the process of conversion will reinitialise the journals. We highly recommend that fsck.gfs is run successfully before attempting to convert a filesystem. Many of the on-disk structures are identical between GFS1 and GFS2, so the conversion process updates the journals, a few items of incompatible metadata (mostly indirect pointers and inodes) and adds the per-node directories required by the gfs2meta filesystem. The conversion process is performed in-place and does not require any extra disk space so that it is possible to successfully convert a GFS1 filesystem that is completely full. Always ensure you have a complete backup of the data on any filesystem before starting the conversion process. OPTIONS
-h Help. This prints out the proper command line usage syntax. -q Quiet. Print less information while running. -n No to all questions. -V Print program Version information only. Print out the current version name. -v Verbose operation. Print more information while running. -y Yes to all questions. By specifying this option, gfs2_convert will not prompt before making changes. EXAMPLE
gfs2_convert /dev/vg0/lvol0 This will convert the Global File System on the block device "/dev/vg0/lvol0" to gfs2 format. gfs2_convert(8)
