Convert GFS to GFS2
I have 3 server with cluster and connect to Hitachi SAN storage. They using LVM and cluster using GFS. Each node share same partition. All machine using Centos. But not sure which version.
I need to convert from GFS to GFS2. Does anyone have any experience do this kind of task? Please share with. What is step by step do i need to do?
What version of CENTOS?
yum provides */gfs2_convert
Should be in the gfs2-utils package
gfs2 does not use cdpn's, so read the man pages or Red Hat documentation
back up ALL of the data, the conversion will irreversibly alter the filesystem, so if there are any problems, you may hose the filesystem. If PV's are coming from a SAN, make sure the status is good, make sure multipathing is working properly.
gfs_fsck before the conversion
READ THE MANUAL and understand it.
