Hi good day.
We have a Proxmox system installed on a B560M DS3H V2 motherboard (Core i9-11900 11th gen, 64GB RAM). It have been working with no mistakes about a year, but since some months ago it started to randomly shutdown (sometimes it suddenly shutdown). We have clean reinstalled proxmox in a new NvME disk. Then CPU shutdowns stopped, but still being rebooting randomly.
After several tries and tests (Memtest86 test passes, power supply replacement) i've tried to set min and max ARC non persistent (following instructions on https://forum.proxmox.com/threads/disable-zfs-arc-or-limiting-it.77845/). It's strange, but that worked, and server have no reboots on about 10 days.
Weird thing is that we have no zfs storages, we just use LVM for VM data storage, and ext4 for local PVE storage.
I've make persistent changes adding lines in /etc/modprobe.d/zfs.conf specifying "options zfs zfs_arc_min=8059738368" and zfs_arc_max.
Server remains beween 4-8 days without troubles and unexpectedly reboots again.
Can someone give me any clues about my trouble, or telling me why could zfs ARC affecting my server even when i don't use zfs pools at all, or if i completely disable zfs on my server could affect in something else.
Thank you!
