backup to non-working NFS

[zystem]

vzdump do not check NFS drive before and during backup and do not unlock VMs on drive error
Proposed fixes:
1) Before locking each vm in list check storage free space and storage is writable
2) Stop backup and unlock VM on any backup error
3) Optional. Stop backup of other VMs on storage error
4) After backup was finished check that VMs is not locked

As workaround
rename vzdump to vzdump.old
create script in /usr/bin/ named vzdump

 #!/bin/bash
IN="$@"

function check()
{
timeout 30 ls $STORAGE &>/dev/null
[ $? -ge 1 ] && { echo "ERROR: $STORAGE/ does not exists"; exit 1; }

FREE=$(timeout 30 df -Pk "$STORAGE" | grep -v 'Filesystem' | awk '{print $4}')
[ $FREE -lt 33554432 ] && { echo "ERROR: insufficient space in $STORAGE"; exit 1; }

timeout 30 touch $STORAGE/.dummy
[ $? -ge 1 ] && { echo "ERROR: $STORAGE/.dummy do not writable"; exit 1; }
}

while [[ $# > 0 ]]
do
    case $1 in
        --storage)
            shift
            STORAGE=$1
            ;;
        --exclude)
            shift
            EXCLUDE=$1
            ;;
        --all)
            shift
            ALL=$1
            ;;
    esac
    shift
done
STORAGE="/mnt/pve/$STORAGE"

if [[ "$ALL" == "1" ]]
then
    GREPEXCLUDE=$(echo $EXCLUDE | sed 's/\,/\\|/g')
    [[ "$GREPEXCLUDE" == "" ]] && GREPEXCLUDE='VMID'
    VMLIST=$(qm list | grep -v 'VMID' | awk '{print $1}' | grep -v "$GREPEXCLUDE")
    IN=$(echo "$IN" | sed 's/--all 1//' | sed "s/--exclude $EXCLUDE//" )
else
    VMLIST=$(echo "$IN" | sed 's/--.*$//')
    IN=$(echo "$IN" | grep -o '\-\-.*')
fi
for i in $VMLIST
do
    check
    timeout 28800 vzdump $i $IN
done

It would be nice directly from Proxmox. This is an importend thing. We have Nagios to see up coming problems with NFS Storage.
