    Hi, I am trying to recover a kvm guest but when type ” rear -d -v recover” , it does not go forward and fails generating the following error
    mount.nfs: portmap query failed: RPC: Remote system error – Network is unreachable
    ERROR : Mount command ‘mount -v -t nfs -o nfsvers=3,nolock <nfs-server-ip:/ /tmp/rear.ZBovVKifdgtx1zE/outoutfs’ failed.
    Please advise

      Hi Jack,

      I believe your rear export location is not properly exported. First try to mount it manually. If worked, then go for rear. From the error it seems you have port connectivity issue.

      1. Check you have network connectivity with nfs server. : –>ping nfs_server from recovery point.
      2. Try to mount the exported filesystem -> mount -t nfs nfs_server_ip:/exported_dir /local_mount

    I already get the rear-localhost-iso, but may I know for the other like “backup.tar.gz” that your show above do i need to create this or it already been create with ” sudo rear -d -v mkbackup”

  3. Adibb says:

    1)I successful make “rear-localhost.iso”, do I need to make “backup.tar.gz”?
    2)Can I make pendrive as bootable instead burn to CD/DVD? because I already try use pendrive as bootable, it cannot load to “REAR” interface

    Please advise.
