Thanks Ray!
Is it feasible to export GFS to NFS clients?
And one more interesting thing. Wikipedia (
http://en.wikipedia.org/wiki/Global_File_System ) says that GFS2 is
supported only starting at kernel 2.6.19 but on my CentOS 5.5 uname
says:
[bepstein@dellnikon ~]$ uname -a
Linux dellnikon 2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:35 EDT 2010 i686
i686 i386 GNU/Linux
[bepstein@dellnikon ~]$
Could thins be a problem?
Boris.
