[PVE-User] Backup to samba share stalling/locking up

[Bart Lageweg | Bizway]

Hi Lindasy,

We are using the rack QNAP on 2 locations with NFS, backup first to local and copy to QNAP (40+ nodes).

/etc/vzdump.conf

Script: /usr/local/bin/backup-hook.pl

#!/usr/bin/perl -w
# hook script for vzdump (--script option
use strict;

print "HOOK: " . join (' ', @ARGV) . "\n";

# config
my $phase = shift;
my $mode = shift; # stop/suspend/snapshot
my $vmid = shift;
my $vmtype = $ENV{VMTYPE}; # openvz/qemu
my $dumpdir = $ENV{DUMPDIR};
my $hostname = $ENV{HOSTNAME};
my $tarfile = $ENV{TARFILE};
my $logfile = $ENV{LOGFILE};
my $backuplocatie = "/mnt/pve/sharenameNFS/dump";

my %dispatch = (
        "job-start"     => \&nop,
        "job-end"       => \&nop,
        "job-abort"     => \&nop,
        "backup-start"  => \&nop,
        "backup-end"    => \&backup_end,
        "backup-abort"  => \&nop,
        "log-end"       => \&log_end,
        "pre-stop"      => \&nop,
        "pre-restart"   => \&nop,
);

sub upload {
        system("mv -f $backuplocatie/vzdump-qemu-$hostname-$vmid.vma.lzo $backuplocatie/vzdump-qemu-oud-$hostname-$vmid.vma.lzo");
        system("cp $tarfile $backuplocatie/vzdump-qemu-$hostname-$vmid.vma.lzo") == 0 ||
        die "upload cp $tarfile $backuplocatie/dump/vzdump-qemu-$hostname-$vmid.vma.tar.lzo  backup-host failed";

        print "HOOK: upload " . $tarfile . " to $backuplocatie/vzdump-qemu-$hostname-$vmid.vma.lzo done\n"; }

sub nop {
        # nothing
}

sub backup_end {
        upload($tarfile);
}

sub log_end {
#        upload($logfile);
}

Seeing this in dmesg
