    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...

    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...

    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...

    [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...
