similar to: mapper device perms on reboot

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: LUN 0 on

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

Hi all, I am trying to configure a failover multipath between 2 GNBD devices. I have a 4 nodes Redhat Cluster Suite (RCS) cluster. 3 of them are used for running services, 1 of them for central storage. In the future I am going to introduce another machine for central storage. The 2 storage machine are going to share/export the same disk. The idea is not to have a single point of failure

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.

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

So I'm working with the iSCSI Initiator and an EqualLogic SAN. I'm not sure when this might have happened, but it appears that the /dev/sdc device is missing, yet the /dev/sdc1 partition exists AND is mountable. Is there a method to re-create the /dev/sdc device? I cannot dd or fdisk it, obviously, but I can mount the /dev/sdc1 partition and it works just fine. Not having the /dev/sdc

Hi Dumb question i think but how can i make devices permissions persist after a reboot. I dont think i have come across this issue before but i have some SAN disks that need to be oracle:dba as their perms but after a reboot they reset back to brw------- 1 root root 120, 49 Nov 30 10:40 /dev/emcpowerd1 any thoughts? thanks

Hello All: Had an issue after upgrading to the latest CentOS kernel from kernel-2.6.18-164.11.1.el5 to kernel-2.6.18-164.15.1.el5 on an IBM HS21 blade with SAN boot. Upgrade went fine, but after rebooting the system was unable to find /boot even though it was mounted. The reboot displayed an error with fsck.ext3 that /dev/mapper/mpath0p1 was not found, which was the /boot volume. I reverted

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: SERVER:/ # mount.ocfs2 /dev/mapper/mpath0 /mnt/temp/ mount.ocfs2: Invalid argument while mounting

Using CentOS 5.1, though with a few hours work I could update to 5.2.. I can install to SAN with a single path no problem but I'd like to be able to use dm-multipath. From the kickstart docs it seems this is supported but there is no information as to what the various options mean http://www.centos.org/docs/5/html/5.1/Installation_Guide/s1-kickstart2-options.html -- multipath (optional)

HI, On a RHEL5 box, i tried to directly run guest which was issued by libguestfs virt-xxx commands as below. But after some minutes, it exited exceptionally.

Hi RIch It got solved.I updated the newer vmlinuz file with the older one after enabling the virtio modules with (m) option. Thanks for the wonderful support you provided me.I'll now ryo to boot my VM from the cloud and let you know if any further issues. I'm now getting following logs... libguestfs-test-tool ************************************************************ *

Hi, I would like to change permissions of /dev/sda* and /dev/hda* files to 0644. I added the following rules to 99-udev.rules files: KERNEL=="[hs]d*", OWNER="root" GROUP="disk", MODE="0644 After restarting udev by strat_udev, I checked that permissions were changed: [root at gini rules.d]# ll /dev/sda* brw-r--r-- 1 root disk 8, 0 Sep 2 2009 /dev/sda

CentOS 4.6 x86_64, Dell PE2950 with DRAC5, onboard SAS RAID 1, 2 arrays. After booting installed system, /dev/sda exists but does not appear to be a hard disk. fdisk -l displays nothing for sda. CentOS is on /dev/sdb and the second RAID 1 array is now /dev/sdc. It's been suggested (in the Dell Linux mailing list) that it is related to the virtual CD device of the DRAC. But why would it
