David Teigland 91ee025d5b cache: change cachevol flags for backward compat ... A cachevol LV had the CACHE_VOL status flag in metadata, and the cache LV using it had no new flag. This caused problems if the new metadata was used by an old version of lvm. An old version of lvm would have two problems processing the new metadata: . The old lvm would return an error when reading the VG metadata when it saw the unknown CACHE_VOL status flag. . The old lvm would return an error when reading the VG metadata because it would not find an expected cache pool attached to the cache LV (since the cache LV had a cachevol attached instead.) Change the use of flags: . Change the CACHE_VOL flag to be a COMPATIBLE flag (instead of a STATUS flag) so that old versions will not fail when they see it. . When a cache LV is using a cachevol, the cache LV gets a new SEGTYPE flag CACHE_USES_CACHEVOL. This flag is appended to the segtype name, so that old lvm versions will fail to use the LV because of an unknown segtype, as opposed to failing to read the VG.		2019-10-15 09:05:52 -05:00
