Re: Can not mount an ext2 file system rw immediately after creating it ?
If you were reading the posts about this you'll be interested in the following response: There is a big difference and it has already be reported as a bug. The current mke2fs creates (by default) filesystem with sparse superblocks, which need a 2.2.x kernel to work. The mke2fs does notb check the current running kernel neigther does it warn about this. You can create the old stly fs by adding an option to mke2fs: "mke2fs -s 0 -r 0" (should work) More about this is in the manpage to mke2fs. By the way, update your kernel why your at it. :) May the Source be with you.

Re: Can not mount an ext2 file system rw immediately after creating it ?
Run `ls -i /sbin/mkfs.ext2 /sbin/mke2fs'. You will see that they are the same inode - therefore they are the same file with two names hardlinked. Bob _ |_) _ |_ Robert D.

Re: Can not mount an ext2 file system rw immediately after creating it ?
I have managed to work around it by using mke2fs that was running from an old (Hamm ?) rescue disk. I can not say for sure but it seems to me that there is a difference between the current (unstable) mke2fs output and the old (Hamm) one. For example, the current version says the superblock backups are stored in 3 places while the old one uses much more. Yet I am using the unstable mount so it seems to me there might be a problem here. > > hi ya > > > I can not mount an ext2 file system rw immediately after creating it.
