Rsync on Truenas shutdown VM!

[Maconly34]

when I launch a copy with Rsync from an internal Pool (RaidZ2) to an external Pool via a USB 3.1 port, after a while the TrueNAS VM crashes (shutdown).

The copy speed can rise to 450 MB/s...
If I restrict the Rsync speed to 300 Mb/s I don't crash any more!

Do you have a solution to this high-speed crash problem ?

THANK YOU

What is your setup? The RaidZ2 is on Proxmox or on TrueNAS VM? Please provide a little more information on how the whole thing is structured.

The RaidZ2 pool was created on TrueNAS Scale 2024. Copying is done via a USB 3.1 port in passthrough on the PC and in Thunderbolt 4 on the external unit (Qnap TL-D800C) containing the pool of 8 disks to be copied. below screen copy of TrueNAS VM)
Command line :

rsync -avh --bwlimit=50M --progress /mnt/Prox2_Pool/ /mnt/master_pool/

I'm doing the test on another (min) PC with the extension plugged into a USB 3.2 port and Rsync to the main PC on the network - no bugs for 2 days. Debian VM under Proxmox to do the Rsync.
Command line :

rsync -avz --ignore-existing --progress /Prox2_Pool/data/media/movies/ admin@192.168.0.71:/mnt/master_pool/data/media/movies/

Thanks in advance for your help,
Bruno

You know that your "Min RAM: 4 GiB" config could force TrueNAS down to 4GiB of RAM and that TrueNAS got a minimum hardware requirement of 8GB?

My Rsync were done with Truenas in 32 GB and without balooning, only after the bugs I switched to balooning 4/32 because I thought it might be due to OOM Killer.
In addition, my rsync, which has been running for 3 days with this memory configuration (see below), has not crashed

Well, I think I've scared everyone off
