What version are you using? We had exactly the same issue with Redhat 4 and PowerPath 4.5. We managed to make it work correctly playing with modeprobe.conf. It seems that they fixed the installation with PowerPath 5.0 because we don't have to change anything to the configuration anymore after a new PowerPath installation since we're using it. -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of Shelton, Darren Sent: mercredi 17 octobre 2007 20:02 To: 'General Red Hat Linux discussion list' Subject: RE: Problem Mounting EMC Lun via fstab Powerpath is loaded via kernel mods. Have a look in /etc/modprobe.conf.pp and /etc/modprobe.conf. All of my volumes are in the LVM, and i dont have any issues with those being mounted at boot, but ive not ever tried to mount filesystems on the devices outside of the LVM. darren -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of Chuck Sent: Wednesday, October 17, 2007 11:40 AM To: redhat-list@xxxxxxxxxx Subject: Problem Mounting EMC Lun via fstab I have a RHEL 5 system that is trying to mount an EMC lun during boot. When I have it set in /etc/fstab is complains that the device doesn't exist. If I enter the root password it puts me into a read-only filesystem where I can't modify /etc/fstab. (I must boot into rescue mode using cd to fix it) /etc/fstab: /dev/emcpowera /u01 ext3 defaults 0 2 However, if I don't mount it via fstab and wait until the system is booted to mount it -- it mounts fine. I'm guessing that powerpath is not being started early enough or its taking longer than it should to initialize. Im mostly a sun guy so where exactly should power path be started or is it somehow called from somewhere else? Im not even seeing an entry in /etc/rc2.d or /etc/rc3.d that starts power path. There is a script in /etc/init.d, but I cannot determine from where and when it is called, if it even is. (the script doesn't have the normal chkconfig run level config info near the top like most do) But somehow once the system is booted power path is running and the emcpowera device has been initialized. Unfortunately I can't use native linux multipathing on this node.
