[pve-devel] nexenta rollback problems.

[Alexandre DERUMIER]

mmm, maybe, need to be tested. (my nexenta test box is down for now, I'll can test it not before friday).

I found an article here
COMSTAR: Keeping GUID's with a new Backend Device
https://www.illumos.org/boards/1/topics/639

it seem to be possible to specify the guid with stmfadm command 
(with ssh, and not the nexenta api, so I don't know if it's break the nexenta view of the luns)

stmfadm create-lu -p guid=*LUN GUID* /dev/rdsk/...



I'll tell the question to nexenta support.

Seems import_lu does the trick. Do you think that will work? 

sub nexenta_import_lu { 
my ($scfg, $zvol) = @_; 

nexenta_request($scfg, 'import_lu', 'scsidisk', "$scfg->{pool}/$zvol"); 
} 

sub volume_snapshot_rollback { 
my ($class, $scfg, $storeid, $volname, $snap) = @_; 

nexenta_delete_lu($scfg, $volname); 

nexenta_request($scfg, 'rollback', 'snapshot', "$scfg->{pool}/$volname\@$snap", ''); 

nexenta_import_lu($scfg, $volname); 

nexenta_add_lun_mapping_entry($scfg, $volname); 
}
