Drives totally disappear from the machine randomly till reboot

[formytech]

Like vanish from the disk menu and on shell, once rebooted there fine for a while, usually on heavy io, i have replaced the drives, controller ext, system is fine on windows server on its own. i have been dealing with this for almost a year, it started with proxmox 7.2 i have tried every file system and config i can think of.. nothing seems to help it can be SSD or hdd it still randomly loses it. anyone have any ideas?

Hi,
do you get anything in the system logs/journal around the time the issues happens? Are the drives healthy when checking with smartctl? What about the temperature?

Please also post dmesg output after the disks disappeared.
