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.
Kernel ring buffer is renewed with each boot and newer messages
overwrite older messages. So, you will want to save or clear the ring
buffer with demsg(1), save a SMART full report, exercise the disk with
dd(1) and/or a SMART test, save the ring buffer, save a SMART full
report, and analyze everything to see if you have disk problems, SATA
problems, and/or system problems. Once everything passes without error,
the disk is ready to be put into service.
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.
This and other threads have led me to the conclusion that consumer SSD's
are meant for devices that are off most of the time -- e.g. notepad,
laptop, desktop, and workstation computers. If you put them into a NAS/
file server and run them 24x7, they will die sometime after 2 years.
So, I suggest:
1. Build a storage server using NAS or enterprise HDD's. Use an
enterprise SSD or DOM for the OS. Run it 24x7 or shut it down as you like.
2. Use your Asus PRIME Z370-A II as a workstation. Install the WD
Black M.2 NVMe PCIe SSD. Connect the optical drive to the first
motherboard SATA port. Install Debian onto the WD Black. Then, connect
the five Samsung EVO 870's to the remaining motherboard SATA ports. Set
them up as a 5-way mirror (RAID1). Use the Samsung RAID as a scratch
disk for your 3-D work. As the Samsung's die off, replace them with the
Gigastones. Shut it down when you are not using it.
3. For Amanda, either add more HDD's to the storage server or build
another server. If another server, shut it down when you are not using it.
