Multipath-root (mpath) problems with CentOS 5
...v/sdd And now after rebooting the system, root device multipath (mpath0) doesn't work anymore.. initrd seems to use/mount /dev/sda* partitions instead of mpath0 device. In fact the whole mpath0 is not started up. The weird thing is that the other LUN is now using multipathing instead.. using mpath1 device. How can I fix that? I'd like to use multipathing for both LUNs, also for root device. If I regenerate initrd with verbose flag, it just sets up the mpath1, not mpath0. I guess that's because mpath0 is not running when regenerating initrd. I have edited /etc/multipath.conf and...

ISCSI help
I am fairly new to ISCSI and SAN technology but having recently invested in the technology I am trying to find out exactly what can and can not be manipulated, filesystem wise, without requiring a reboot. I am using the inbuilt software ISCSI initiator and multipathing in CentOS 5.1. My steps so far. Create 10GB volume on SAN # iscsiadm -m session -R # fdisk /dev/mapper/mpath0 # kpartx -a
