I recall a good bit of discussion about this a while back... There is a part of the wiki devoted to this topic: http://www.gluster.org/docs/index.php/Setting_up_AFR_on_two_servers_with_pre-existing_data Also I wrote a 'set-attrs' script for setting glusterfs attributes on existing data, essentially "converting" it to gluster format. Included below... It will ignore anything that already has glusterfs attributes, and will set them on anything that doesn't. #!/bin/bash DIR=$1 if [ -z $DIR ] then echo echo "Error - no path was given." echo echo "USAGE: set-attrs /path/to/check" echo echo "Run set-attrs to check all files and directories in the" echo "given path for glusterfs attributes. Any files without" echo "a glusterfs version will be given a version attr of 2" echo "and a createtime attr equal to the files last modified time." echo echo "Output information is logged to syslog (usually /var/log/messages)" echo exit 0 fi set_attrs() { get_ver="getfattr --absolute-names -n trusted.glusterfs.version" set_ver="setfattr -n trusted.glusterfs.version" set_ct="setfattr -n trusted.glusterfs.createtime" if test "`$get_ver $i 2>/dev/null | fgrep -c trusted.glusterfs.version=`" = "0" then mods=$((mods+1)) # comment out next line to turn off logging initlog -n set-attrs -s "Setting attrs on $i" CT=`stat -c %Y $i` $set_ct -v $CT $i $set_ver -v 2 $i fi } mods=0 checks=0 initlog -n set-attrs -s "Starting a set-attrs run on path: $DIR" for i in `find $DIR -print` do set_attrs $i checks=$((checks+1)) done initlog -n set-attrs -s "Completed. $checks checks and $mods mods in this run" exit 0 ----- Original Message ----- From: "Stas Oskin" <stas.oskin at gmail.com> To: gluster-users at gluster.org Sent: Wednesday, February 4, 2009 6:39:34 PM GMT -05:00 US/Canada Eastern Subject: Transforming server with existing data into a GlusterFS node Hi. I wonder, is it possible to transform a server with existing data into GlusterFS node? Meaning, define a volume then gradually move all the files into it? Or it's much better to start a new one from scratch?
