Multipath-root (mpath) problems with CentOS 5
Hi list!
I have a server with dual port Qlogic iSCSI HBA. I set up the same LUN for
both ports, and boot the CentOS installer with "linux mpath".
Installer detects multipathing fine, and creates mpath0 device for root disk.
Installation goes fine, and the system boots up and works fine after the
install from the multipath root device.
After install the setup is like this:

/etc/rc.local and /etc/fstab
Upon system boot, is it ok to mount OCFS2 mounts from /etc/rc.local
rather than /etc/fstab ?
Are there any downsides to using rc.local that you are aware of?
Example /etc/rc.local script:
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

mapper device perms on reboot
How can I get the mapper device permissions set on reboot?
When I attempted to try this...
# cat /etc/udev/permissions.d/50-udev.permissions | grep mapper
mapper/mpath*:oracle:dba:0660
But it did not seem to work...
# ls -l /dev/mapper/mpath*

iscsi and the last mile...
I have a new Dell PowerEdge 2950 running CentOS 5.0 out-of-box and a Dell
MD3000i. I am new to iscsi and, with google and included documentation,
am having a heck of a time trying to get the RAID volumes I have created
on the 3000i to be seen by the OS as usuable drives. I have printed out
SMcli and iscsiadm documentation.
I have asked on the linux-poweredge at dell.com site, too.

Mount fails with error status -22?
Hi,
I am little puzzled. I looked through the mailing list archive and some
other sources but doesn't seem like anything anyone encountered.
I have two systems with attached HP SAN. I'm using SLES 10.1 with
multipath-tools. When trying to mount OCFS2 device I get this:

Multipathing with Sun 7310
Dear list,
we have a relatively new Sun Storage 7310, where we connect CentOS 5.5
Servers (IBM LS21/LS41 Blades) via Brocade Switches, 4GBit FC. The Blades
boot from SAN via qla2xxx, and have no harddisks at all. We want them to
use multipathing from the very beginning, so /boot and / are already seen
by multipathd. Problem is, that the Sun 7310 has two storage heads which

working with multiple password protected iSCSI targets on one host
Hi,
How do I setup multiple password protected iSCSI targets on Linux?
I know that mounting a password protected iSCSI target requires modify
these records with the appropriate values:
node.session.auth.username = My_ISCSI_USR_NAME
node.session.auth.password = MyPassword
discovery.sendtargets.auth.username = My_ISCSI_USR_NAME
discovery.sendtargets.auth.password = MyPassword

Best Practice to remove an ISCSI LVM from a system
Hi,
I'd like to know what would be the best way to remove an iscsi lvm
storage from a server. (removing all reference to that storage etc.)
The storage in question will be reset and reformated and used on a
different server; so no LVM export is needed.
Do I have to do lvremove ..., vgremove ..., pvremove ... and do an
iscsiadm -m node -T ... -p ... -u and
iscsiadm -m node -o delete -T ...

iSCSI storage pool autostart
Hello everyone,
I have recently installed libvirt 1.0.0 and am having a problem with my
iSCSI storage pool's autostarting. They are just going to an inactive state
right after a reboot of the host. However once the startup is complete I
can manually start the pool without problem.
I am getting the following errors in the libvirtd.log file but they don't

Connect libvirt to iSCSI target
Hi!
I'm new to libvirt and face problems connecting to an iSCSI target.
What I intend to do is to connect libvirt (I tried virt-manager and
virsh) to an iSCSI target and then boot from the LUNs which contain
the VMs.
I followed the documentation¹ but got stuck at section 12.1.5.4.3.

Mounting mpath devices in RHEL 5
I'm seeing some strange behavior from OCFS2 while trying to mount
mpath/dm-multipath devices under RHEL5. Sometimes I can mount the
EMC-connected, dual-pathed volumes just fine and sometimes I get "device
busy" errors. I've tried mounting by label and also by explicit
/dev/mapper/mpathXpY name with the same unpredictable behavior. I've
also noticed that sometimes when a

How to force iscsi to see the new LUN size
Hi,
I increased the size of one of the LUNs and on CentOS 5.4 if I restart
iscsi (`service iscsi restart`) I'll see the the new size but this will
disconnect all other LUNs.
I'm hoping that there is isciadm or some other command that will force
iscsi to rediscover the LUNs but I can't seem to be able to come up with
one.
Resize2fs says that there is nothing to be done. I'm

Possible to run iscsi-target and initiator on same server?
I am trying to install Oracle RAC in a two node cluster for testing
purposes, so performance is not something that concerns me. I just want
to go through the process all the way to creating a database. I have all
the prerequisites except the shared storage and thought I'd give this a
try.
