Well, I'm pleased to say that the new WWW/XMPP/MQTT NUC server is up
and running, although I still haven't made the commitment to switch of
the old Raspberry Pi 3. One reason for this is that I didn't yet have
a backup of the new server: it took me nearly a full day to set up and
there was a *lot* of software to tweak. Of course, I run a daily
backup of important files and directories (and who doesn't eh?) but as
there's a lot riding on this server I normally run a full disk clone
using Clonezilla. Believe me, there's nothoing quite like being able
to hot-swap a drive over in the event of problems...
The other reason for waiting was that I read a few reviews of SSDs and
learnt that althought the Corsair Force LE200 is a good device, it's
slow. When you've been used to a Raspberry Pi, "slow" is a relative
term so the disk seemed okay to me, but then I read about it being
targetted at first-time laptop replacement scenarios, and I was
somewhat concerned. I tried to find an alternative and had hoped to be
able to get a WD RED 120Gb SSD, but such things don't exist, so I had
settle for as WD Blue 250Gb SSD instead.
Next day delivery's a wonderful thing and I duly set up another disk
stress test, with the following results over 12 hours:
So while the web server will mostly be running in read mode, the other
applications will be writing more and anything that can be done to
speed this up will be welcome.
If the new SSD works as anticipated I'll switch over the web server
next week and repurpose the Raspberry Pi 3. The Pi-hole server could
do with an update, so that's sorted! And just in case, I've ordered
*another* WD Blue SSD which will become the new clone backup. Great
fun eh?!
