Re: [Users] [node-devel] GlusterFS on oVirt node

I reinstalled node and remounter / rw then I checked fs before activating host (in oVirt Engine) and after (which files have been changed)... The "ro" problem seems to be in /var/lib/glusterd/. Is there any way I can change node so this directory would be mounted rw? And to persist this setting after reboot.
