  1. Ceph over multipath device or something else

    I was not aware on this. I will try and check, thank you!
  2. Ceph over multipath device or something else

    Because it's not a shared storage on the Proxmox part, it's a local dir storage mounted on OCSF2. Proxmox is seeing that storage as a directory storage.
  3. Ceph over multipath device or something else

    So, adding up: your advise is to use LVM (not Thin!) on the multipath mapper volume on every node, configuring it as "shared". This way I would have HA but not snapshots. Right?
  4. Ceph over multipath device or something else

    OCFS2 is a shared file system. So basically every node is seeing the same storage in the same way and they can share the same files without conflicting each other. Yes, I know how Ceph works, but I was thinking that it would work on multipath block devices. It will work if I would have local...
  5. Ceph over multipath device or something else

    Ok, but now using OCFS2 as a local directory storage I can have snapshots if I use qcow2 images. But I cannot have HA. So I have to choose between snapshots and HA, right? I cannot use CIFS or NFS because that FC storage is directly attached to Proxmox nodes. Ok Ceph is not a solution, I...
  6. Ceph over multipath device or something else

    Ok, thanks! Yes, /dev/mapper/STORAGE-DATA is the block device from multimapper, so I would be able to create a physical LVM volume on it. Just one question: should I create an LVM or LVM-Thin volume? Because LVM will not give me snapshot, but LVM-Thin yes. So I don't need OCFS2, fine!
  7. Ceph over multipath device or something else

    So could I create one LVM physical volume over the top of the OCFS2 volume directly into the /dev/mapper/STORAGE-DATA device? So basically pvcreate /dev/mapper/STORAGE-DATA and so on? What about GFS2? Do you consider it better than OCFS2? Thanks!
  8. Ceph over multipath device or something else

    Thanks! I will check. In your opinion, could I make a LVM physical volume over the OCFS2 volume? Thanks!
  9. Ceph over multipath device or something else

    Hi, I have 4 Proxmox servers, all connected to a Fiber Channel storage using multipath which is serving two volumes: STORAGE-DATA and STORAGE-DUMP. Every node is showing 4 sd* devices (2 per volume) and one mapper device per volume: root@node2:~# multipath -ll STORAGE-DATA...
  10. Why my ZFS dataset is consuming much more disk space?

    Thanks Fabian! I cannot understand how I can solve this problem: now I'm creating a new virtual machine on another server to solve the disk problem and I don't want to replicate this problem. Could you send me some hints on what I have to do to avoid this on the new server? I've just created a...

  13. Why my ZFS dataset is consuming much more disk space?

    Hi, my virtual machine has two ZFS drives, one 60 Gb and one 18 Tb: root@gus3:~# grep zfs /etc/pve/qemu-server/3001.conf virtio0: local-zfs:vm-3001-disk-0,size=60G virtio1: local-zfs:vm-3001-disk-1,size=18T I have 4 10 Tb disks on this server and I'm running out of disk space, so I'm...
  14. VMs on ZFS not booting after disk replacing

    Yes, it was turned off. Many years, more than 5, almost 7-8. I am using ECC memory. Thanks!
  15. VMs on ZFS not booting after disk replacing

    I understand that, but it's very strange that this happened after a disk replacement, isn't it?
