ext4

I'm trying to resize an ext4 filesystem on a Fedora 11 box. Using fsdisk and lvm, I was able to grow the partition and logical volume containing the filesystem.

When I try to run resize2fs on the device containing the filesystem (/dev/sda2 in this case), I get:

"Device or resource busy while trying to open /dev/sda2, Couldn't find valid filesystem superblock"

I've tried this from a rescue disk that doesn't have the filesystem mounted, no joy.

Maybe resize2fs doesn't know about ext4?

Strange ZFS hidden filesystem problem

Half of my ZFS filesystems are hidden in ZFS-fuse. Here's my story: So, I love ZFS. I used it for about six months on FreeBSD, but due to it crashing the kernel during heavy inter-filesystem IO load, I tried switching to Solaris 5.10. That was good, but when I attempted to do an import of my Version… >>> More
