Eric Sandeen reported that Fedora's mke2fs when compiled for ppc was creating a file system which caused problems with resize2fs -M. Closer examination showed that the problem was file system which looked like this: Filesystem features: ext_attr dir_index filetype sparse_super Inode count: 512 Block count: 1247 ... Group 0: (Blocks 1-1024) Primary superblock at 1, Group descriptors at 2-2 Block bitmap at 66 (+65), Inode bitmap at 67 (+66) Inode table at 68-99 (+67) Group 1: (Blocks 1025-1246) Backup superblock at 1025, Group descriptors at 1026-1026 Block bitmap at 1090 (+65), Inode bitmap at 1091 (+66) Inode table at 1092-1123 (+67) It's not obvious to me why Fedora's ppc mke2fs is creating file systems like this (I can't reproduce this on debian ppc systems), but resize2fs -M should be able to deal with such file systems, which is what this test is designed to check.
