[conspire] 1:2.1.29-1+deb10u5? Re: upgrade-in-place to Mailman 2.1.30 and want to test Mailman3?

[Rick Moen]

Here's an idea:  I already had in mind to buy replacements for the pair
of Vantec external cases for 2.5" SSDs, and for the USB cables providing
power to those enclosures (and possibly also for the eSATA data cables,
though we don't have any suspicions about those cables' reliability), so
how about I start with acquiring current, larger 2.5" SSDs?

/me looks at newegg.com, is appalled at how junked-up the site now is.
I'd heard they had new management.  Ugh, it shows.

Current mass storage is a mirrored pair of Samsung SSD 840 PRO Series
256GB, best of breed for their day, notably using MLC NAND flash rather
than cheap-ass, slow TLC (triple-level cell) NAND, the greater quality
attested by the 5-year (now expired) warranty rather than the commodity
sludge's shorter warranty.  Cost was about $1/GB when new.

Looks like, in the 2.5" "traditional" (heh!) form factor, as opposed to
racy M.2 stuff that is not a go for the CompuLab box, the Samsung SSD
860 Pro Series, in several capacities, is a recent successor to the 840
PRO Seriea.  

In 1TB sizes, Newegg offers new for $520, used for $200.

Except this is not being sold by Newegg but rather _through_ Newegg by
some other clowns named "The Best Deals for You Store".

I am -not- getting warm-fuzzies about 2024's iteration of Newegg.  Where
_do_ people shop for reasonable deals from non-flaky firms, in 2024?
Central Computer in Santa Clara, maybe?


Anyhow, that troubling detail aside, suppose I were to buy a pair of 1TB
SSDs and 2.5"-compatible external cases plus power ("USB") cables for
them.  Then, we could put guido into degraded-RAID1 mode with just one
of the 256GB drives, booting from that, and adding one of the 1TB drives
to the system, then set up a new guido on the 1TB drive (with LVM and
other changes deemed desirable), migrate everything to it, set the 1TB
drive to be bootable, power down, remove the 256GB drive, add the second
1TB drive, power back up, remirror the RAID1 array.

I'm used to doing that sort of thing with not only all services offline
but also and in single-user maintenance mode; don't know how you feel
about that.  System being down for an afternoon is perfectly fine.

At that point, we'd have a lot more space to play with, and LVM if you 
really think it's justified.  Personally, I am not convinced about the
need for that additional abstraction layer, especially if one has enough
spare space, and also if necessary is willing to have downtime while
moving around data and remaking filesystems (which I am willing to
have).

What do you think?
