I have worked quite a bit with CentOS 4.x with SAN, multipathing, LVM etc. The way I mount my file systems is using a script that is called during startup that runs fsck, imports the physical volumes, and volume groups, activates the logical volumes, creates the mount point if needed then mounts the volume, I mainly made it for software iSCSI due to the iscsi stack loading after the system mount process. I adapted it to my fiber channel systems as well and it worked great(mainly so I could have a consistent experience between FC and iSCSI).
Hmm.. not sure about older versions of CentOS but for lvm over iscsi in 5.2 all you should need is
/dev/foo.vg/foo.lv /foo xfs _netdev,noatime,rw 0 0
in /etc/fstab and iscsi node startup set to automatic (which is the default I believe). _netdev being the key as it will mount it after iscsi is loaded and connected.
Found the root issue here I believe in /etc/rc.sysinit
if [ "${RHGB_STARTED}" != "0" -a -w /etc/rhgb/temp/rhgb-console ]; then fsck -T -t noopts=_netdev -A $fsckoptions > /etc/rhgb/temp/rhgb-console else fsck -T -t noopts=_netdev -A $fsckoptions fi
It scans all file systems by default unless the _netdev option is set, whereas in CentOS 4.x it ONLY scans the root file system
if [ "${RHGB_STARTED}" != "0" -a -w /etc/rhgb/temp/rhgb-console ]; then fsck -T -a $rootdev $fsckoptions > /etc/rhgb/temp/rhgb-console else initlog -c "fsck -T -a $rootdev $fsckoptions" fi
I'll think about filing a bug/feature request I think the 'noauto' option should be included in the exclusion list.
Perhaps fsck should be fixed as well, according to the manpage 'noauto' means it won't get mounted when you do mount -a, perhaps it should not get fsck'd either if you do fsck -A
