I recall from prior posts that you are using Informix, is that right? Recent versions of Informix implement the O_DIRECT flag for disk I/O so raw devices are not needed For our Informix installation, we point the server directly at the /dev/sd* devices. The one trick is to create a file in /etc/udev/permissions.d that sets the permissions for the disk devices at boot. # cat /etc/udev/permissions.d/40-informix.permissions sdb5:informix:informix:0660 sdb6:informix:informix:0660 sdb7:informix:informix:0660 # -- Jeff _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos _______________________________________________________________________________________________________ 總會在某些時刻，突然想起舊情人？他 現在過得還好嗎？ http://sev.search.yahoo.net -------------- next part -------------- An HTML attachment was scrubbed...
