I haven't posted them as bugs yet though because I am not sure if some are intentional. The first column of the flags is 'o' when a normal snapshot is taken of a thin volume but is 'V' when a thin snap is used. I haven't checked to see if 'O' is used for merging with thin snapshots. The other issue I have run into is that a thin snapshot doesn't put an 's' into column 1 or column 7. This makes parsing more difficult since a thin volume and thin snap look the same in the flags. It seems that one of the columns could be changed to an 's' without losing any information. The first column also is used for merging 'S' so that would probably be the best one. ~# lvs LV VG Attr LSize Pool Origin Data% Pool_One MyGroup twi-a-tz- 1.00g 9.96 fat_snap1 MyGroup swi-a-s-- 112.00m thin_vol2 0.00 thin_vol2 MyGroup owi-a-tz- 2.00g Pool_One 4.98 ~# lvs LV VG Attr LSize Pool Origin Data% Pool_One MyGroup twi-a-tz- 1.00g 9.96 thin_snap1 MyGroup Vwi-a-tz- 2.00g Pool_One thin_vol2 4.98 thin_vol2 MyGroup Vwi-a-tz- 2.00g Pool_One 4.98 Should I post these as bugs?
