On RHEL5 systems, you have to set the SAN-based filesystems with the "_netdev" option in the fstab to get the system to boot properly.
Maarten Broekman From: [email protected] [mailto:[email protected]] On Behalf Of Arvind Navale Sent: Wednesday, November 04, 2009 12:42 PM To: RHEL-v5 OS Group Subject: [rhelv5-list] Powerpath and LVM2 with RHEL-4.x/5.x Hi Folks, I have configured ext3 file system on SAN disks using LVM2, for SAN path redundancy we are using EMC Powerpath 5.3 SP 1. I have enabled LVM filters so that I can avoid duplicate path warnings when I run LVM commands. For test purposes I am rebooting the server to make sure the file system on SAN disk gets mounted w/o issues but apparently I am seeing issues where OS drops to maintenance mode after not able to see the LVM file system created on SAN disks. I commented the entries for these FS in /etc/fstab and rebooted the machine. Once the server comes I am able to manually mount the File systems. From my understanding, I see that Powerpath drivers/process is not started at the moment when the OS is trying to mount the LVM FS while booting and so its not able read the metadata information from the EMC pseudo devices since the LVM filter which I have setup is preventing LVM to read the same metadata from regular device path for the disk. Is there any kind of fix for this which anybody know? I am familial with similar kind of issue in Sun Solaris OS with Veritas Volume Manager and Powerpath and the fix in Sun Solaris-10 was to specify kernel parameter in the system file. So is there a similar kind of parameter in Linux too? Appreciate everyone's time regarding this. Thank you, AN _____ Bing brings you maps, menus, and reviews organized in one place.
