ISTR there are config option(s) to mount ext{2,3} using ext4. On at least one of my machines I see two such messages, but the first is for ext3 and the second for ext2 :
[ 1.765843] sd 0:0:0:0: [sda] Attached SCSI disk [ 1.792078] EXT3-fs (sda6): error: couldn't mount because of unsupported optional features (240) [ 1.795575] EXT2-fs (sda6): error: couldn't mount because of unsupported optional features (240) [ 1.818698] EXT4-fs (sda6): mounted filesystem with ordered data mode. Opts: (null) [ 1.821899] VFS: Mounted root (ext4 filesystem) readonly on device 8:6. I can't remember when this started, and google is useless (loads of references to converting *to* ext4, or for an obsolete config option), but at some time the ext4 driver became able to mount ext3 and ext2 - if those were enabled. ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
