Proxmox and Lenovo DS2200: Storage Visibility Issue

Hello everyone,


Freshly arrived from VMware, here I am new to the world of Proxmox. I am trying to set up a test environment to offer server infrastructures. I have two Lenovo x3650 servers with internal storage, plus a Lenovo DS2200 datastore. The datastore is connected to the servers with two SAS cables (SAN) for each servers.


I installed Proxmox on the internal storage of both servers and created a cluster. The logical disks of the datastore are visible in the disk section of both Proxmox servers. I can create ZFS storage on the datastore, but once done, this storage is not usable on both servers and becomes exclusive to one or the other.


I tried to configure multipath, then to create a new shared volume, but that doesn't work either because on one of the two servers, the available space is not visible.


I'm a bit lost on the right architecture to use. A helping hand would be really precious for the continuation of my project.


Thank you in advance for your help!

Hi Philipp,

Yes, i try to follow the guide, there is somes more informations. I have setup 3 volume in the multipath conf, but only 2 appears one the first node.

Fdisk on one of the two nodes

Hello Yoann,
maybe there is a missing config at the DS2200 system, so that the first host is not allowed to communicate with the LUN you want to assign to "mpatha".
Can you check this at the SAN?

Philipp
