similar to: San boot failure after upgrade to latest

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

Hi, I got few servers (IBM HS20,HS21 blades, IBM xSeries 3650 & others) connected to a dual fabric san throught Qlogic HBA's (23xx, 24xx). Multipathing is done with device-mapper-multipath. On CentOS 4.x i can scan for new scsi devices without any problems, get them up with multipathing & use them without any problems. However, after i started installing CentOS 5.1 (did not

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'm running a Centos 7.2.1511 freshly installed on a SAN device. Everything is fine on the SAN side, but I have an issue with multipath or udev or systemd, I'm not sure. I when I boot my machine with the multipathd service enabled at boot, boot fails beacause some partitions on the multipathed device are missing from /dev. >From the boot rescue shell, if I do a fdisk -l

HI Dom0 is CentOS 5.2, 64-bit, Xen version 3.2.1 and 3.2.2. I got Fiber SAN disk system and 2 servers and i am making shared LUN available to both servers. Then i got multipath layer running on both Dom0s and so Xen is seeing device-mapper file, instead of two /dev/sdX devices, then i have setup Xen domU (HVM Windows 2003) using /dev/mapper/sharedLUN as physical storage to my windows server.

Hi all, I have problem with my servers. I use two of HP Blade Servers and RHEL 4.6 installed on them, and have IBM DS4700 connected to them. In those servers are running RHCS (Red Hat Cluster Suite) with GFS for handling Oracle Database. Yesterday, I had missing one partition from the storage, suddenly. I called IBM and they suggested to use RDAC. The question is, Why should use IBM RDAC for

Hi, WARNING: Long post ahead I have an issue when starting multipathd. The kernel complains about "blk_cloned_rq_check_limits: over max segments limit". The server in question is configured for KVM hosting. It boots via iBFT to an iSCSI volume. Target is COMSTAR and underlying that is a ZFS volume (100GB). The server also has two infiniband cards providing four (4) more paths over SRP

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* brw-rw---- 1 root disk 253, 2 Feb 26 20:56 /dev/mapper/mpath0 brw-rw---- 1 root disk 253, 5 Feb 26 20:56 /dev/mapper/mpath0p1 brw-rw---- 1 root disk
