So...can I or can I not use snapshots with reiserfs? The snapshot was taken of a currently mounted and functioning (reiserfs module loaded...compiled into the kernel, actually) so if I did the snapshot correctly there should be a filesystem there. I'm going to wipe it out (nothing on it but some test files) and try again with ext2 and see what happens. This should work, shouldn't it? -- Tracy Reed http://www.ultraviolet.org
