Cluster Networking for Multi-tenant isolation in Proxmox with OpenVSwitch
This is probably the most complex part of the setup. It involves network configuration of the cluster in a way that the instances running on different nodes can still talk to each other. This is needed in order to provide…
Adding ZFS over iSCSI shared storage to Proxmox
PVE-4.2 has built in support for ZFS over iSCSI for several targets among which is Solaris COMSTAR. I built a ZFS VM appliance based on OmniOS (Solaris) and napp-it, see ZFS storage with OmniOS and iSCSI, and managed to create…
Adding iSCSI shared volume to Proxmox to support Live Migration
We will use Multipath for link HA and improved performance. Install the needed packages first: root@proxmox01:~# apt-get install open-iscsi multipath-tools Then we discover the target and login: root@proxmox01:~# systemctl start open-iscsi.service root@proxmox01:~# iscsiadm -m discovery -t st -p 192.168.0.180 192.168.0.180:3260,1…
Highly Available iSCSI ALUA (Asymetric Logical Unit Access) Storage with Pacemaker and DRBD in Dual-Primary mode – Part2
This is continuation of the Highly Available iSCSI ALUA Storage with Pacemaker and DRBD in Dual-Primary mode series. We have setup the HA backing iSCSI storage and now we are going to setup a HA shared storage on the client…
Highly Available iSCSI ALUA (Asymetric Logical Unit Access) Storage with Pacemaker and DRBD in Dual-Primary mode – Part1
I already wrote a post on this topic so this is kind of extension or variation of the setup described here Highly Available iSCSI Storage with SCST, Pacemaker, DRBD and OCFS2. The main and most important difference is that thanks…
Highly Available iSCSI Storage with SCST, Pacemaker, DRBD and OCFS2 – Part2
This is continuation of the Highly Available iSCSI Storage with SCST, Pacemaker, DRBD and OCFS2 series. We have setup the HA backing iSCSI storage and now we are going to setup a HA shared storage on the client side. iSCSI…
Highly Available iSCSI Storage with SCST, Pacemaker, DRBD and OCFS2 – Part1
SCST the generic SCSI target subsystem for Linux, allows creation of sophisticated storage devices from any Linux box. Those devices can provide advanced functionality, like replication, thin provisioning, deduplication, high availability, automatic backup, etc. SCST devices can use any link…
