| | | | | | | | | | | | | | | | | shared-last-sector problem. After this change, even if there is more than one provider with the same last sector, the proper one will be chosen based on its size. It still doesn't fix the 'c' partition problem (when da0s1 can be confused with da0s1c) and situation when 'a' partition starts at offset 0 (then da0s1a can be confused with da0s1 and da0s1c). One can use '-h' option there, when creating device or avoid sharing last sector. Actually, when providers share the same last sector and their size is equal, they provide exactly the same data, so the name (da0s1, da0s1a, da0s1c) isn't important at all. - Provide backward compatibility. - Update copyright's year.

* - Add genid field to the metadata which will allow to improve reliability a bit.pjd2004-12-251-0/+1
| | | | | | | | | | | | | | | After this change, when component is disconnected because of an I/O error, it will not be connected and synchronized automatically, it will be logged as broken and skipped. Autosynchronization can occur, when component is disconnected (on orphan event) and connected again - there were no I/O error, so there is no need to not connected the component, but when there were writes while it wasn't connected, it will be synchronized. This fix cases, when component is disconnected because of I/O error and can be connected again and again. - Bump version number. - Implement backward compatibility mechanism. After this change when metadata in old version is detected, it is automatically upgraded to the new (current) version.
