Once the rebuild started, I noticed an email from smartd, saying that
the _other_ drive on the Promise controller (/dev/hde) had had errors.
So I foolishly checked it out with smartctl,



Can you please share with us newbies why using "smartctl" in such situation is foolish, so we don't make the same mistake ?


Thanks.

John

at which point everything
went to hell. /dev/hde now clicks repeatedly and refuses to work for
more than a minute or so, while /dev/hdg is partially destroyed from
being re-added. The rebuild was 3-4% complete when hde died.
