OpenATTIC 2-node cluster setup
[serialposts] OpenATTIC is an opensource converged storage that I think has a great potential to become a unified SDS for virtualization platforms. It offers features like CIFS, NFS, iSCSI and CEPH storage backends, mirrored volumes via DRBD and support for…
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 RBD (CEPH) remote cluster storage to Proxmox
There is a 3 node CEPH cluster running on the office virtualization server that is external to PVE. The latest PVE though has built in support for CEPH using pveceph package so in case we have PVE cluster of 3…
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…
ZFS storage with OmniOS and iSCSI
The following setup of iSCSI shared storage on cluster of OmniOS servers was later used as ZFS over iSCSI storage in Proxmox PVE, see Adding ZFS over iSCSI shared storage to Proxmox. It was inspired by the excellent work from…
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…
Ceph cluster on Ubuntu-14.04
As pointed on its home page, Ceph is a unified, distributed storage system designed for performance, reliability and scalability. It provides seamless access to objects using native language bindings or radosgw (RGW), a REST interface that’s compatible with applications written…
