  1. iSCSI, snapshots and LXC within a PVE cluster

    Hello, I’m currently installing 3 pve hosts in cluster mode with an iSCSI EMC array, everything is redundant : 2 ToR switches for the servers , 2 switches for the iscsi traffic. We’ve chosen this solutions to migrate from ESX (too expensive). I’ve read a few articles / posts related to PVE...

  3. iSCSI with CHAP

    I am trying to get my Proxmox VE 7.3-4 setup with iSCSI and CHAP. (Without CHAP was easy.) I have multiple iSCSI shares with different CHAP username/password combos. I see whispers that this should be possible, but nothing for multiple username/password combos. Any one have any information?

  5. migration path from ZFS via iSCSI to ceph?

    When it comes to storage, we have been using ZFS over iSCSI in our clusters for years. Now for a couple of new projects, we require S3 compatible storage and I am unsure about the best way to handle this situation. I am tempted to use MinIO, but I've read mixed reviews about it and Ceph seems...
  6. problems with shared LVM on top of iSCSI after dropping multipath

    Hello. We have a cluster of 7 nodes. VMs and LXCs are stored on external storage, on a shared LVM, via iSCSI. We recently had to move from a 2 x 1Gbps iSCSI multipath connection to a 1 x 10 Gbps FO ethernet (single link iSCSI connection, no multiphating). The iSCSI storage has 4 ethernet ports...

    Hey everyone, a common question in the forum and to us is which settings are best for storage performance.

  10. iSCSI Live Migration Nimble

    Hi Everyone, One of my major clients is considering PVE but I've run into the same snag as earlier this year. The organization has several HPE Nimble SANs and they aren't going away as far as I can tell. HPE Nimble is block storage only, so iSCSI is basically the one and only solution...
  11. ISCSI as a shared drive to deploy templates from

    Good Day, I have added a remote ISCSI share from a starwind vsan. Setup was flawless and I can see the drive and space assigned. I also kinda already know the answer (been testing it) but would like a official confirmation from anyone in case I am doing it wrong. Is it possible to use a ISCSI...

  13. 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...
  14. LVM/LUN's Suddenly missing

    I started up my proxmox server today and found that I cannot boot any of my VM's. All the iscsi disks don't seem to be working. Here is the output: iscsiadm: Could not stat /etc/iscsi/nodes//,3260,-1/default to delete node: No such file or directory iscsiadm: Could not add/update...

  16. [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...

  19. 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...
