Hi,

I discovered a couple of discussions of the phenomenon, the upshot of which
were:
1) That's what you get when you purchase cheap SSDs.

2) SSDs belonging to the same software RAID show identical serial numbers
in software, but these numbers don't match the serial numbers printed on the
SSDs themselves.

Those URLs are identical. (OMG ! Is it contageous ?)
Number 2 would match my suspicion that some layer in the disk driving
gets confused and mixes up the serial numbers.
But you said *similar*.
By "colliding serial numbers" i mean indeed "identical serial numbers".
How cheap the disks may ever be, that would be no excuse for not making
them individually distinguishable.
As Gene's threads have too many movable parts
for me to follow, on that point I couldn't say.
This one begins to gain presence in the web. So one can use search engines
and AI to untangle its sub-threads. I meanwhile participate in two of them:
serial number collision, rsync caused OOM killer (solved now, but how ?).
By LABELing the partitions uniquely, that problem so far as I can see,
is solved.
The OOM death of the system was the xfce4 terminal apparently being set
for unlimited scrollback and that was eating the memory. Switching to
Konsole with has the ability to control the scrollback to 200 lines, and
its taken all 32G's as .cache and 1536 1k blocks of swap, and its
working w/o any OOM actions I've detected.
Have a nice day :)
