Ssd read problems - Centos 9 stream

Post by mamax » 2022/12/06 13:39:46

Hello everyone, I have a problem i think with ssd disks and Centos Stream 9; when I start the machine everything is ok, if I run sha256sum on a file everything is ok; if i wait ex. 2 hours and I redo sha256sum each time obtain different results.
Now I explain the whole story.
I had a Centos 7 server, amd ryzen threadripper 1920x processor, with 4 Samsung QVO 860 2 Tb raid 0 ssds (therefore 8Tb) where qemu was installed with many virtual machines. No problems.
Needing more space I removed the 4 ssds and put a Samsung QVO 870 8tb and a Samsung EVO 870 4tb. Since then the machine has become unstable.
Thinking that the problem was too recent disks for that operating system, I installed centos9 Stream, but I didn't solve anything.
Then I found this statement to add in /etc/default/grub
GRUB_CMDLINE_LINUX=" libata.force=noncq"
And something has improved, but not much.
Now the situation is as I explained at the beginning.
Tips ?

Maybe see if there's any BIOS and firmware updates?
I have a Dell R740 server with a 860 EVO 2TB disk,
and it was constantly rebooting. A BIOS update fixed it.

Check your RAM too, try memtest86+.
The future appears to be RHEL or Debian. I think I'm going Debian.
Info for USB installs on http://wiki.centos.org/HowTos/InstallFromUSBkey
CentOS 5 and 6 are deadest, do not use them.
