Are these filesystems mounted when running this? (mounted readonly?). If not, does the segfault occur if the device is unmounted or mounted readonly at the time xfs_db is run? Running xfs_db on a mounted filesystem that is being / has recently been modified is known to be unreliable (the kernel keeps a separate address space for metadata that is not coherent with direct block device access). If this functionality is needed for a mounted read-write fs, new ioctls would be needed... (and kernel code). cheers. -- Nathan -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
