Also about this issuse, I'd like to know if : - Data corruption occurs when creating RO snapshots, - Or if it can occur with just using a FS that already has RO snapshots ? - Or if it can occur when deleting existing RO snapshots with 3.17 ? Which means : If I have mistakenty upgraded to 3.17.2 a system containing RO snapshots and cannot downgrade (big distro and drivers mess...), what is the safest way to go ? And if data corruption occurs, should I expect it to affect snapshots only, or the whole system ? TIA for any insight. -- Swâmi Petaramesh http://petaramesh.org PGP 9076E32E
