This is strange, the destroy vm code is
# only remove disks owned by this VM foreach_drive($conf, sub { my ($ds, $drive) = @_; return if drive_is_cdrom($drive); my $volid = $drive->{file}; return if !$volid || $volid =~ m|^/|; my ($path, $owner) = PVE::Storage::path($storecfg, $volid); return if !$path || !$owner || ($owner != $vmid); PVE::Storage::vdisk_free($storecfg, $volid); }); if ($keep_empty_config) { PVE::Tools::file_set_contents($conffile, "memory: 128\n"); } else { unlink $conffile; } So,If PVE::Storage::vdisk_free is hanging (before the disk have clone), the config file shouldn't be delete the vdisk_free code is $plugin->cluster_lock_storage($storeid, $scfg->{shared}, undef, sub { my ($vtype, $name, $vmid, undef, undef, $isBase) = $plugin->parse_volname($volname); if ($isBase) { my $vollist = $plugin->list_images($storeid, $scfg); foreach my $info (@$vollist) { my (undef, $tmpvolname) = parse_volume_id($info->{volid}); my $basename = undef; my $basevmid = undef; eval{ (undef, undef, undef, $basename, $basevmid) = $plugin->parse_volname($tmpvolname); }; if ($basename && defined($basevmid) && $basevmid == $vmid && $basename eq $name) { die "base volume '$volname' is still in use " . "(use by '$tmpvolname')\n"; } } } my $cleanup_worker = $plugin->free_image($storeid, $scfg, $volname, $isBase); }); if volume isbase (this is the case of templates, the disk volid is base-xxxx), we check if we have clones. (listing all volumes, and check if the volumes have the base image as parent) ----- Mail original ----- De: "Wolfgang Link" <w.l...@proxmox.com> À: "datanom.net" <m...@datanom.net>, "pve-devel" <pve-devel@pve.proxmox.com> Envoyé: Mercredi 21 Janvier 2015 11:05:30 Objet: [pve-devel] Question to ZFSPlugin.pm I implemented the ZFSPlugin for local Zfs use. When I test my adaption of this Plug-in, I recognize that it is possible to erase a template witch has a linked clone. I mean the Zfs-volume will not destroyed but the config of the template. My problem is I can't validate, it on the orginal Plugin, because I have no iSCSI Nexenta/OmniOS. Has the ZFSPlugin the same behavior on iSCSI? regards. _______________________________________________ pve-devel mailing list pve-devel@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel _______________________________________________ pve-devel mailing list pve-devel@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
