Which means it might be useful as an emergency solution while you're waiting for the new disks to arrive. > but yea, smartmontools is a better method to monitor for defects. Indeed, 'smartmontools' for hardware-defects, "fsck" for filesystem-defects. About doing "live" fsck & defrag on a rw filesystem, IIRC Windows NT has a system API for doing e.g. atomic "swap 2 sectors" operations; does 'linux', or any of the filesystem drivers for it, support something like that? -- Jan Claeys -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
