  2. Is there any way that iSCSI can offer snapshots & HA

    Hi Everyone, We've been struggling moving away from a mal-performing CEPH cluster at a customer site for a little while now, however, our NAS supports iSCSI and NFS, but not CEPH or ZFS over iSCSI. Is there truly no solution to include HA, Live Migration, and PBS Live Backups using an iSCSI...
  3. LVM/LUN's Suddenly missing

  5. [SOLVED] iscsi direct lun: vm has wrong partition layout

    I am currently setting up iSCSI storage with direct LUNs. However, VM does not detect any partition (the LUNs already have data on them). I experimented and found that if I create a MBR table (rather than GPT) with a single partition, the VM detects the partition but with an invalid size. Host...

  8. create storage failed: pvcreate error ... device is too small (pv_min_size) (500)

    Hello, I'm in the process of setting up a HP MSA2040 SAN to work with Proxmox. As I just started using a SAN, I have a little over zero knowledge of these things, so there most probably will be errors in my setup (or terms I don't use correctly). Current status is: - MSA2040 is connected via...

  12. Backups from iSCSI backed LVM very slow

    Hello, I've found a few threads about similiar problem but none of them have a solution. We have a 3 node cluster with multipathed iSCSI storage using IBM Storwize SAN. In Proxmox 6.4 which we use, there is a shared LVM created which stores VMs on all nodes. We didn't notice any performance...

  15. correct way to pause ZFS over iSCSI connections

    HI, I need to replace a switch in one of our datacenters, that is used by a couple of PVE nodes for almost anything (corosync, ZFS over iSCSI, node to node traffic for VMs etc.). The replacement shouldn't take long, but still it may take a minute or so. For all the traffic except ZFS over...
