Also, if you don't have the CFS e2fsprogs patches for uninit_groups then mke2fs creates an invalid filesystem if the journal is large (this was an unrelated bug we fixed while testing uninit_groups). Try running e2fsck right after the above mke2fs and you will likely see errors. > jbd2_journal_bmap: journal block not found at offset 31780 on sda7 The problem is that lazy_bg allocates the journal blocks incorrectly, IIRC.
