Is GFS 6.2 same as GFS 2 file system?

Hi,

I have a bit knowledge of GFS. As per my understanding it is the file system used in the cluster environment.

I have a question. Is GFS 6.2 same as GFS 2 files system?
Please some one clear my confusion.

Thanks in advance.

In short no. GFS 2 is the latest version fully supported on RHEL 5 while 6.2 was supported on RHEL 4
