What filesystem is it and how did you mount it with -o clear_cache? If it is your rootfs did you applied clear_cache to /etc/fstab or your bootloader? If it was the latter it won't work. For the rootfs you need to add it to the boot options. For me this worked every time. Josef, is there any way to detect a wrong cache, saved by an pre-2.6.39 kernel and discard it? regards, Johannes -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
