I managed to create bigalloc fs with "mkfs.ext4 -C<cluster-size> -O bigalloc" Filesystem seems to work (only lightly tested) under kernel 3.2.15 Shouldn't mkfs be smart and turn "bigalloc" feature on automatically when "-C" is used? Also should be documented issues that this feature causes in resizing support. Am I correct saying that off-line resizing isn't supported and on-line resizing needs at least kernel version 3.3? -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
