If some existing process has its CWD underneath /thing, then you can access that directory via /proc/<pid>/cwd. You could use debugfs on the root fs, but I wouldn't recommend trying to modify a filesystem while it's mounted r/w. If you can't unmount the SAN because it's busy, you may still be able to move its mount point with "mount --move". If you can allow for it being unavailable briefly you could move it off just long enough to rename the underlying directory, e.g.: mkdir /thing.tmp mount --move /thing /thing.tmp mv /thing /thing.orig mkdir /thing mount --move /thing.tmp /thing rmdir /thing.tmp -- Glynn Clements <glynn@xxxxxxxxxxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-admin" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
