hi guys.. my proxmox server somehow was found turned off. It was in a powered down state automatically. And I dont know how.

I suspect a crash. but if it was to crash, then it should be in a hung state or should reboot im thinking. but not powered down.

how can i check what happened?
do you want the syslog?
can i check elsewhere?
what else do you need to check?

im running v3.4, with ZFS softwear raid (raid1 - mirror) (via your build process).
 
hi thanks for the reply..


below is the syslog. i cannot find anything.. well i dont understand how to read it. i really appreciate any help.

http://pastebin.com/raw.php?i=ui3J2Mpy


The last logged item before the issue was at 12:17:01
And the entry at 12:39:57 must be the start of the server coming back up.



 
Sorry, can't help. I had the exact same issue a few days ago and thought it was a sudden fluke on the hardware. RAM and DISK CHecks brought nothing to light. My Proxmox Logs show nothing as well, looks like a complete freeze without error indicating the arrival of the sudden death.

But this box is running the latest from testing. None of my stable / subscription machine have every shown anything like it.
 
interesting.. thanks for the reply.
i'm using Proxmox VE 3.4. is that not the stable version?
 
Hi,
I have proxmox VE 3.4 and I have exactly the same problem, I found anything abnormal in my syslog, but My server crashes every 3-4 days. anyone can help?
 
Try sticking to the original build from the iso without upgrading / updating. That I so build seems to be more stable. Only upgrade when a new image is out.
Else get a subscription... And upgrade.
 
How about some computer specs? (CPU, memory - ecc or non-ecc, motherboard, hard drives w/ age, etc.)

hi, I have a server Dell PowerEdge R220 with 1 cpu intel xeon 8 cores, 32g memery ECC, 2x1T sata3, server run in proxmox ve 3.4 upgraded from 3.3 with 4 kvm machine.

So looks like I spoke too quick. it went for months without a crash.. and all of a sudden, looks like it froze.
the server summary shows monitoring has stopped as well.

at Apr 27 22:17:01 was the last event before it was powered back on.

Any help anyone?? I have the full log if anyone needs it.

Hmm... looks like these servers crashed after the same event.

Hello, I have the same problem - the automatic restart of the server, or someone did it solve?
 
not solved. well I've rebuild mine to 4.2 now, so i hope the problem goes away.
 
I'm seeing what I think are these same hangs/crashes every 24 to 48 hours or so too.
My machine stays powered on but everything is hung and unresponsive.
Neither syslog or the BMC logs show anything interesting.
This is running 4.2...

I originally thought this was a memory issue, but I swapped to different sticks (ecc reg) and ran memtest for quite a few passes without issues or errors.

The other thing I thought could cause it was high IOH temperature (my board is an X8DTH-if which has two IOH chips right next to each other that get really hot.).
To combat this I stuck an 80mm fan directly on top, but this hang/crash seems to still occur.
I'm going to attempt a fresh install from the latest ISO, but if that doesn't fix it, I'm just going to something else

The last entry in syslog always is the bit about

Code: 
rrdcached[4234]: removing old journal /var/lib/rrdcached/journal/rrd.journal.1462685004.325075
I see this task runs every hour, so it might just be that there is nothing else that may be hitting syslog between this and the hang, but it's the only thing that I have to work with.
 
I have the same problem, and also all been checked. One thing that has not checked a RAID. Do you have a solution hardware or software?
