The partitioner that sets this up previously setup a bit over 2x the
memory, 18Gb for swap, then surveyed the system and found 2 more swaps,
dutifully adding then to the /etc/fstab it wrote. So at that point I had
nearly 50Gb of swap available in 3 pieces/drives.

In a production environment, raid is ok if you can dedicate at least 5
drives, we have an older centos setup at the tv station with its data
array a 5 drive lashup, scary fast, but also quite complex to setup and
maintain. For some reason (they are very well cooled) the drive life
seems to be limited to less than a year of 24/7 uptimes. So the last time
Jim bought drives for it, he bought a 12 pack about 3 years ago. And they
took that as a hint, and only 1 has failed since. OTOH, the drive I use
for amanda now has
9 Power_On_Hours 0x0032 051 051 000 Old_age Always - 43534
on it, and has not recorded an error as I have its self-test enabled. So
it would email me for a sneeze. Except the test log ends at about half is
spin up hours, so I wonder to myself when that was disabled. I just
initiated a -t long since the drive will not see any activity again for
about 14 hours. I wonder it it ran out of buffer space at 21 reports?
Back on the thread..
Can linux now be booted as of old, with its vmlinuz file 3.5 Terrabytes in
from the start of the disk? That implies a bios a lot bigger & smarter
than what was available at the time, circa 2007 or so, when I bought this
Asus M2N-SLI Deluxe board, with a 2.1 GHz phenom, and built this machine.
Removing the boot partition removes the guarantee that boot related files
will be within reach of the bios. However, 50Gb is out of line as I have
been using 1Gb for years, which has all sorts of cruft I haven't used in
yonks in it. So I'll likely fix that and slide the rest of it back out
before I put another install disk in the optical drive.
Thanks Gary.
Cheers, Gene Heskett
