8b1ae3c140 Don't store fid in VG metadata cache to avoid clvmd segfault. (2.02.34) 2008-04-14 19:24:16 +00:00
Dave Wysochanski
5ca6698f12 Add lv_is_active() to determine whether an lv is active. 
Handles non-clustered as well as clustered.  For clustered,
the best we can do is try exclusive local activation.  If this
succeeds, we know it is not active elsewhere in the cluster.
Otherwise, we assume it is active elsewhere.

a2cb3d17a7 When mirrors are created with the --nosync option, a status flag 
(MIRROR_NOTSYNCED) is added to the LVM metadata.  This flag is
not cleared when converting to linear.  Subsequently, if you
up-convert the linear to a mirror, the flag remains - even though
an up-convert will always force a complete resync.
