Cool, two things I didn't know about.
Is fstrim only for SSDs? I just tried it on a partition on my spinning,
soon to be upgraded HD and got a "discard operation not supported" message.
thanks

You should make sure fstrim runs to clean up your free space.
Do you have a lot of free space? A tool that can copy while ignoring
the free space will make it faster. I personally use Clonezilla.

Soliciting advice from the pros... (and experienced amateurs)
I find myself getting ready to do a hard disk upgrade on my
desktop. In
the past, I would only do this when it was time to upgrade the
system so
I would just do a fresh install on the new disk.
This time, my system is as current as can be and everything's working
great so I'm thinking why not just copy everything over to the new
disk.
I have an external USB enclosure for the new disk so can in theory
set
it up before installing it in the machine. I can see two basic
options:
1) make an fs on the new disk and cp -a oldroot newroot (or rsync for
that matter)
2) dd if=olddevice of=newdevice
What does everyone else do in this situation? Are there options I
haven't considered?
Re #1, I'm worried about getting the device files set up ... I don't
think cp will make them. It seems rsync has an option to do that,
but
do I dare use it? I presume I'll have to run lilo again. (This is a
geriatric pre-UEFI machine.)
Re #2, does this get me out of having to run lilo? Not that it's so
hard. I guess if I'm dd'ing a partition (/dev/sda1,2,3) and not the
whole disk (/dev/sda), I probably will have to.
Anyway, grateful for any thoughts... Hope you folks have a
comfortable
place to work. It's a steambath out there. At least no tsunamis.
ciao
