Mirrored LV contains "sub LV"s. e.g. "lv0" contains "lv0_mimage_0", .., "lv0_mimage_n" and "lv0_mlog". "_mimage" and "_mlog" are reserved words, so normal LVs never has these in their names. To rename mirrored LV, we have to rename those sub LVs accordingly. The patch is tested on CVS head (pre 2.02.28) for the following cases: - normal LVs (linear, striped, snapshot) for regression check - mirrored LVs (-m2, -m1, --corelog for both active and inactive) Example: [Before renaming] # lvs -a -o name LV l [l_mimage_0] [l_mimage_1] [l_mlog] # dmsetup ls testvg-l_mlog (253, 9) testvg-l_mimage_0 (253, 10) testvg-l_mimage_1 (253, 11) testvg-l (253, 12) # lvrename testvg/l testvg/newlv Renamed "l" to "newlv" in volume group "testvg" [After renaming] # lvs -a -o name LV newlv [newlv_mimage_0] [newlv_mimage_1] [newlv_mlog] # dmsetup ls testvg-newlv_mlog (253, 9) testvg-newlv_mimage_0 (253, 10) testvg-newlv_mimage_1 (253, 11) testvg-newlv (253, 12) Thanks, -- Jun'ichi Nomura, NEC Corporation of America -------------- next part -------------- A non-text attachment was scrubbed...
