Faced with a similar problem as Lisi's during this install as I had 4
drives in it then and 3 swaps mounted, I did remove the other drives, so
my fstab is by UUID for everything I am using. Memory is now faint, but
ISTR, when I first rebooted after plugging in the drive amanda uses as a
tape vault, I ran blkid and used the UUID to add that drive to fstab.
When I do a new install, I generally do it on a new drive, but its been
in the machine long enough to go get any firmware updates it needs and
reflash them. Every drive I've bought locally or from NewEgg or Tiger
Direct in the last 5 years has had old, buggy, sometimes slow firmware
in it, so they all will probably need reflashed for using them for work.
I might add that my drive failure rate since I started doing that has
fallen off a cliff.
sda says 23,000+ hours
sdb says 58,000+ hours
Now, I do note that sdb has a re-allocated sector count of 25, but no
clue as to how many spares are left but that does sound like its time to
retire it. Both are older 1 terrabyte drives that I planned on
replacing this summer. The newer crop of drives seems to be maturing,
but I also expect the newer drives will be 4 kilobyte sectors too.
Hopefully by then our disk tools will have caught up and can
transparently use both GPT partitions AND 4Kb sectors.
The current boot drive is a 4Kb sector drive, and I frankly had one hell
of a time using the installers disk tools, getting it properly aligned
so its read/write speed was at least usable.
Thanks Felix & everybody that has read this far.
Cheers, Gene Heskett
