Description

This seems to be related to the size of the LV. If I run the same but add 1G to an existing 1G LV it works, and our test suite using smaller sizes works, but when I use the same sizes as above I see the same failure. When lvm is calculating the necessary metadata size (4MB for each 500MB of data, +4MB) it is not accounting for "initial_sectors", which is much smaller than the amount of normal metadata sectors. Given certain sizes, the growth of initial_sectors can cause the metadata device to be too small. Currently working to confirm the ratio needed for initial_sectors. pushed to master https://sourceware.org/git/?p=lvm2.git;a=commit;h=ad773511c59aea239592c014a2dab4161ed92214 (The tests below are using fewer stripes than shown above, but my tests with this many stripes still had the same problem.)
