If the disk is going bad, it will fail. 2) Run as root `smartctl -A /dev/sdx` (for each sdx) and look at the "WHEN_FAILED" column; it will be "-" if not failed. 3) Run as root `smartctl -a /dev/sdx` (for each sdx) and look at the whole output. 4) Run as root `smartctl -t long /dev/sdx` (for each sdx) and wait until the time the test should finish, then view the results with `smartctl -l selftest /dev/sdx` (for each sdx) or `smartctl -a /dev/ sdx` (for each sdx). See `man smartctl`. Note that the new disk health monitoring tool "palimpsest" in package gnome-disk-utility is panicky and not to be trusted, unless you like buying lots of hard drives. It doesn't just look at "WHEN_FAILED", but has its own criteria such as nonzero Reallocated_Event_Count, which is fairly normal for a modern drive that has been in use for a while. A nonzero Current_Pending_Sector or Offline_Uncorrectable are bad, as they mean data loss, though not general drive failure. I recommend enabling Automatic Offline Testing with `smartctl -o on /dev/sdx` (for each sdx), which will do a surface scan every few hours, giving the best chance to repair or recover any sectors that are going bad. -- ____________________________________________________________________ TonyN.:' <mailto:tonynelson@xxxxxxxxxxxxxxxxx> ' <http://www.georgeanelson.com/> -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
