I suggest you to mount with -o attrs (not remount) also look in the kernel logs for any problems, there is a requirement that before you have attrs code working, you need to have special flag in superblock set (which you can set with reiserfsck --clean-attributes) Bye, Oleg On Tue, Jul 15, 2003 at 03:10:55PM -0400, D.A.M.
