Re: [lfs-support] EXT3-fs (sda4): error: couldn't mount because of unsupported optional features (240) , during kernel boot

Usually it's when you've used create-filesystem flags that conflict with how you're wanting to mount the filesystem. What filesystem type/format do you _think_ should be on /dev/sda4 ? How did you create that filesystem: with a gui, or command-line; and did you use any 'extra', non-default options? And how are you trying to mount the filesystem: e.g. what is in your /etc/fstab for /dev/sda4 ? Does the log give any indication, nearby to the above lines that you post, of what the conflicting features are? rgds, akh Answers will be appreciated. Thanks. -- -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

Answers will be appreciated. Thanks. This looks perfectly normal. There is a kernel option to allow ext4 to handle ext2 and ext3 filesystems. I think you probably made an ext4 filesystem on sda4, and after this it should get mounted as ext4. I see something like these messages on every boot. So, do you have a problem [ i.e. it failed to boot ] or are you just concerned about reported errors ? ĸen -- das eine Mal als Tragödie, dieses Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

You didn't answer the question, so I assume you are just concerned about reported errors. You seem to have been able to log in to the LFS system to run that 'cat'.
