Greetings all;
As usual, the man page may as well be written in swahili. The NDE
syndrome, meaning No D-----d Examples.
I have those 2 2T SSD's with a gpt partition table on both, allocated
as sdc1 and sdk1, formatted to ext4, named and labeled as lvm1 and lvm2.
Temp mounted as sdc1 and sdk1 to /mnt/lvm1 and /mnt/lvm2
How do I create a single managed volume of labels lvm1 and lvm2 of
these to make a single volume that I can then rsynch /home to it,
then switch fstab to mount it as /home on a reboot?
If it works, I'll kill the raid10, reformat it and make it another
lvm for amanda to use.
I am determined to remove the raid10 /home from the list of suspects
causing my system lockups anytime a program such as OpenSCAD or
digiKam, even firefox wants to write a new file to my /home
partition. This delay does not lockup the whole shebang, already
open files in other workspaces seem to run at normal speeds, but
opening a simple gui file requester to get where to put the file, and
possibly rename it, takes anywhere from 30 seconds minimum to around
5 minutes just to draw the requester on screen. And while you are
waiting, wondering if you even pressed the mouse button, there is
ZERO acknowledgement the button has been pushed. The mouse can be
moved normally, but until the requester is fully drawn on screen, no
other button clicks are registered.
This software raid10 worked perfectly for buster and bullseye, but
its been nothing but a headache on bookworm. And only one has tried
to help, suggesting strace, but its output is so copious it overflows
the 32G of main memory in this machine so I can't go back to the
actual programs start with the trace. I have used it in the past,
decade or more back up the log, and while it was noisy then, this is
unusable.

Not LVM, but FWIW I previously had my data on 2 @ 1.5 TB HDD md RAID1
LUKS ext4 on Debian 9:

Thank you David, printed for study, but looks like it still uses mdadm
which I wanted to avoid in order to make the test isolation complete.
Okay. But, I very much doubt that Linux md is the problem.
Given the various posts, my best guess is that there is a software
problem with Bookworm, the version of openscad on Bookworm, etc., and/or
some misconfiguration of your system. It might be worthwhile to put an
ext4 file system onto one of the new 2 TB SSD's, mount it for testing,
copy a file onto the 2 TB file system, configure your app(s) to put
temporary files there, and test. That would let you know if your /home
RAID10 is a problem.
