Those attributes are worrisome. Especially Reallocated_Sector_Ct and
Runtime_Bad_Block -- I am confident those are inside the SSD.

That is equivalent to 10.2 years at 40 hours/week.

TBW specification for 1 TB drive is 600TB. You are at 19.7.
relatively low IOW.

I am still uncertain if those are internal SSD errors or SATA errors.
Please check if you see matching errors in dmesg(1).
There aren't any. Those hours would very closely correspond to my
attempts to rsync and the OOM deamon killed the machine, which it did
around 10 times. So logging by then had been killed. That to me is the
smoking gun. 2T is enough /home for the nonce. so I'll do the rsync
thing going the other direction, using it for a backup of /home until
I'm ready for trixie.
However I am tempted to zero the drives an recreate the raid w/o
formatting since the mdadm seems capable to installing itw own
filesystems to use the whole drive unpartitioned, giving me a backup
that sizewise is about the same as the single 2T drive has now.
And although my single experience with lvm over a decade ago was a total
disaster, made out of used spinning rust I may now see how the other 4
2T's assembled as a lvm for amandas vtapes as an 8T lvm to backup the
whole system, which in addition to the 4 cnc'd machines, has over the
last 5 years seen a train of 3d printers go by. If all 3, currently a
WIP, get rebuilt, the smallest is 305 by, the largest is 400 by. And
all I hope will lay plastic at 200+ mm a second. Normal consumer stuff
is 40 to 60.
Obviously I have an eclectic choice of too many hobbies. ;o)>
Now if curiosity doesn't kill this cat, I need to find some breakfast
and git to it.
Thank you David, take care, stay warm dry and well.
