So, for a cluster, using fencing, gfs, and all the needed tools to run
a cluster, is there
any reason not to use selinux ? I am looking to see if cluster
operator use or do not
use selinux...
Beware that "permissive" mode, far from being benign, can be as
expensive as having SELinux enabled. See
http://www.mail-archive.com/linux-cluster@xxxxxxxxxx/msg08317.html for
some details on GFS and extended attributes.
Oh... I didn't tought of performance influence... That alone is enough to
keep it off completly. We will be hosting a high-volume site where every
millisecond counts. That site is composed of about a million files of
different sorts. So, any added delay in accessing a file is not an option.
