similar to: multipath failover

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 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

I've found discussion about this in list archives, but no final answers. Many helpfull people wrote in the past how to avoid creating DVD (install from network, install from disk, boot this way, boot that way). But, I do need DVD, no way around it. No network, no USB, no floppy, no anything. Placing files on hard drive not an option. Just a DVD-ROM. By Googling around, I found some

Hello, I am trying to find out a best practice for a specific scenario. First of all I would like to know what is the proper way to set up multipath, who should care about it the host or the guest. Right now I have a setup where I have one multipath which sets my host to boot from FC SAN. I have another multipathed LUN in the host which is essentially a dm which I attached to a guest, however

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

Hello I am wondering if anyone este tried this. I Have few CentOS 6.2 systems that are running KVM virtual machines. As storage backend for them I use 2 iscsi targets (based on openindiana). For accessing these disks I use dm-multipath, since I use 2 separate networks for access. For these reasons I want host system to force not to scan dm-multipath disks for partitions. According to
