<font size=2 face="sans-serif">I'm running CentOS 5.9 x86_64 on a machine
I built myself that has 6 SATA II hard drives (4 - 1 TB drives; 2 - 1.5
TB drives) all in several RAID-1 arrays. These arrays were created when
I did the original installation with CentOS 5.1 and each created partition
(both standard and LVM) were built raid 1.</font>
<br>
<br><font size=2 face="sans-serif">Due to some things happening around
the house that required most of my attention, I saw some alerts concerning
drive /dev/sdb but I didn't have time to address it and since I am running
raid 1... One of the tings that happened was my home took a lightening
strike and we were down for 4 days.</font>
<br>
<br><font size=2 face="sans-serif">When we got our electricity back and
I brought the machine back up I noticed that there were only 5 drives listed
and I wasn't getting any more alerts. What was /dev/sdb was
no longer listed with any command (fdisk; cat /proc/mdstat; mdadm --list).</font>
<br>
<br><font size=2 face="sans-serif">I do have a spare drive and my questions
are:</font>
<br>
<br><font size=2 face="sans-serif">Anyone know how I can find the serial
number of the bad drive?</font>
<br><font size=2 face="sans-serif">Once replaced, what is the best way
to get the partitions recreated?</font>
