Greetings all;
I have bought 5, 2T gigastone SSD's, made in Taiwan
I have 2 extra sata cards in this machine, a 6 port cheap
and a twice as expensive on with 16 port, all rated at 6G speeds.
The cheaper one has my home raid10 on it consisting of 4, 1T samsung 870
SSD's first assembled back in buster days.
The newwer 16 port card has 4, 2T gigastone's on it, unused for anything
yet, intending to either make me a new, bigger raid10 for /home, or
maybe an 8T lvm for amanda's vtapes. And a 5th gigastone that I have now
had its data cable plugg into all 3 choices of sata ports,
1, built into an Asus PRIME-Z370-A II motherboard
2, the bargain no name 6 port sata card
3. the more expensive 16 port sata card.
Two of the 4 Samsung drive that make the raid10 I mount as home are
reporting trouble to smartctl, some of that has been posted in the
previous thread.
The 5th gigastone SSD has now been plugged into all three choices via
its data cable mounted to /mnt/homevol by its unique LABEL= in the mount
command, and attempted copy of /home made using this syntax:
$>sudo rsync -av /home/ /mnt/homevol
There is about 350Gb of data to copy. OpenSCAD and 3d printer slicer can
blow up a 200 line plain text module into several gigabytes of gcode.
Problem:
Regardless of the sata port/card this 5th SSD is plugged into, it
appears to me that rsync is overpowering the SSD's write bandwidth and
somewhere between 13.5Gb of data to around 45Gb of data copied, I wind
up with a machine that begins to stutter a bit, and finally htop says
rsync is down to zero cpu, and maybe one more file locks everything but
the mouse up, it still moves but the clock and the rest of the machine
has stopped. This may take 5 minutes, maybe 15 but its the same story 5
times now. by the time I've rebooted, smartctl give the SSD a clean bill
of health. or did til this last try, now it says, for that drive:

Is there a way to throttle rsync to the write bandwidth of these SSD's?
Or do I have a pile of duff SSD's?
Thank you.
Cheers, Gene Heskett.
