thanks for all the help I have reduced the ARC cache to 16GiB and seems to be all good so far, will update here if it crashes again. Seems like an issue that the arc cache does not free up automatically though when memory is low.

Do you have any more info re these issues? I may try disabling ksm for a bit

root@nuc11propve:~# arc_summary | grep "ARC size (current)" ARC size (current): 93.7 % 29.3 GiB

The memory usage seems to creep up over the days - surely if this is the ZFS cache it should be released when in a low memory situation?

attached full sys log of when it happened ( I would have pasted it all in but it was too large) Sep 09 18:40:27 nuc11propve kernel: systemd-journal invoked oom-killer: gfp_mask=0x140cca(GFP_HIGHUSER_MOVABLE|__GFP_COMP), order=0, oom_score_adj=-250 Sep 09 18:40:27 nuc11propve kernel: CPU: 5...

I have been running Proxmox 7 and never had an issue, I have had OOM errors twice in the last two weeks and it ends up killing the VM thats assigned the most amount of memory can anyone explain why this is? I have 64GiB of RAM - I have four containers 103 2.00GiB assigned 104 2.00GiB...

@jsterr using that script I do get a test email - thanks! I was under the impression that starting and then cancelling a scrub would generate an email but apparently it does not. thanks for your help :)

@jsterr if you just start a scrub and cancel it will you get a notification? I have a large pool so not letting it finish to test each time.

@jsterr you can see my comment above I already have that enabled.

I can see the events in the syslog as well Aug 21 13:16:35 nuc11propve zed[991309]: ZFS Event Daemon 2.1.12-pve1 (PID 991309) Aug 21 13:16:35 nuc11propve zed[991309]: Processing events since eid=602 Aug 21 13:16:46 nuc11propve zed[994980]: eid=603 class=scrub_start pool='pool_media' Aug 21...

Thanks for the reply yes I have that set on already - can you confirm should it be postfix for this? ZED_EMAIL_PROG="postfix" Also I do not get the debug file created - /tmp/zed.debug.log any other ideas or where I can check for error messages? I find since proxmox8 now it uses journalctl...

hi I have postfix setup and I get emails ok if do this echo -e "Subject: Test\n\nThis is a test" | /usr/bin/proxmox-mail-forward what should the /etc/zfs/zed.d/zed.rc config be - there is a log of conflicting info on the forums about how to set it up? should ZED_EMAIL_PROG = mail or postfix...

any chance this will be added into the offical build - I find the naming pretty bad when trying to find a particular backup you need to lookup the vm id.

thanks very much for writing this all out - much appreciated. will try it out tomorrow.

@generalproxuser yes I have tried some app amour settings but not managed to find the right combination. Yes if you can find it would be much appreciated, thanks!
