[LU-16331] "lfs find -O UUID" does not match first OST after gap

Related — Thu, 17 Aug 2023 18:44:46 +0000

Running "lfs find -O testfs-OST000a -type f /mnt/testfs" does not correctly find files with objects on OST000a if there is a gap in the OST numbering and this is the first OST number after the gap, but this works properly for finding files on this OST by index number:
