also, I have around 600luns, so maybe lvs try to scan each of them ?

Objet: Re: [pve-devel] vm stop tasks hanging
I think I found the problem:
in Qemuserver.pm : vm_stop_cleanup sub
-> PVE::Storage::deactivate_volumes($storecfg, $vollist);
sub deactivate_volumes {
my ($cfg, $vollist) = @_;
return if !($vollist && scalar(@$vollist));
my $lvs = lvm_lvs (); ------------------------------> this is called, but I don't use lvm
my @errlist = ();
foreach my $volid (@$vollist) {
my ($storeid, $volname) = parse_volume_id ($volid);
my $scfg = storage_config ($cfg, $storeid);
if ($scfg->{type} eq 'lvm') {
my ($name) = parse_volname_lvm ($volname);
if ($lvs->{$scfg->{vgname}}->{$name}) {
my $path = path ($cfg, $volid);
my $cmd = ['/sbin/lvchange', '-aln', $path];
eval { run_command($cmd, errmsg => "can't deactivate LV '$volid'"); };
if (my $err = $@) {
warn $err;
push @errlist, $volid;
}
}
}
}
die "volume deativation failed: " . join(' ', @errlist)
sub lvm_lvs {
my ($vgname) = @_;
my $cmd = ['/sbin/lvs', '--separator', ':', '--noheadings', '--units', 'b',
'--unbuffered', '--nosuffix', '--options',
'vg_name,lv_name,lv_size,uuid,tags'];
maybe adding a
return if $scfg->{type} ne 'lvm'
at the begin of deactivate_volumes sub should help ?

Objet: Re: [pve-devel] vm stop tasks hanging
interesting: when I stop the process, I have this error:
command '/sbin/lvs --separator : --noheadings --units b --unbuffered --nosuffix --options vg_name,lv_name,lv_size,uuid,tags' failed: received interrupt
root at kvm6:~#
I'm using scsi lun directly without lvm, maybe this is the cause of the problem ?

What does an strace -f -p PID of the vm stop command say? It should do
or wait for something. Also does it only happen via Proxmox console or
does it also happen when starting then command via shell?
