Newbie question on mdadm
I recently had to throw out an old NAS I've been using for over 10
years. However I rescued the 2 HDDs and got a dual-slot USB SATA
docking station for them. To my astonishment Fedora recognised them
immediately as a RAID1 array (formatted with XFS) without me doing
anything.
However gsmartcontrol reports that one of the HDDs has internal errors.
Would it be best to correct these using mdadm (assuming they can be
corrected), and if so, how? Or should I do an offline copy with the
docking station's "clone" button?
Are there any general recommendations for monitoring these beasties? I
don't want to change anything for the time being and will be using the
thing mainly for backup, but I see there is such a thing as mdmon which
isn't currently running. Should it be? I have no previous experience
with md devices.
