[DRBD-user] Linstor - snapshot mouting

[Michał Szamocki]

Hi,

I wonder if it's safe to mount lvm snapshot after `linstor snapshot create` command and why it creates lv snapshot with k flag?

Background: I made path to LINSTORPlugin.pm:

<     die "drbd snapshot is not implemented\n" if defined($snapname);
---
>     sleep(5);
>     die "drbd snapshot is not implemented\n" if defined($snapname) && $snapname ne 'vzdump';

<     my $path = "/dev/drbd/by-res/$volname/0";
< 
---
>     my $path;
>     if ( defined($snapname) ) {
>       $path = "/dev/drbdpool/".$volname."_00000_snap_".$volname."_".$snapname;
>       run_command( 'lvchange -ay -K '.$path, errmsg => "lv activate error" );
>     } else {
>       $path = "/dev/drbd/by-res/$volname/0";
>     }
>     print "path:$path\n";

<     die "Snapshot not implemented on DRBD\n" if $snapname;

>     die "Snapshot not implemented on DRBD\n" if $snapname && $snapname ne 'vzdump';
