Nope, we have since replaced all production machines this error occurred on as there seems to be no possible fix for this fairly common problem (they were older AMD machines anyway). My testing machine however still runs into this mystery of a problem every few weeks or so if left on long...

Well, I guess we ruled that out then

After having experienced this issue any number of times, I have started to collect some metrics on the sort of machines it happens on. One thing that immediately stood out to me that on the about ~10ish machines I have actively and extensively run PVE on, this issue has in my case exclusively...

Exact same as original post: root@pve:~# service pveproxy status ● pveproxy.service - PVE API Proxy Server Loaded: loaded (/lib/systemd/system/pveproxy.service; enabled) Active: failed (Result: timeout) since Tue 2016-09-27 14:58:46 CEST; 21h ago Main PID: 830 (code=exited...

Pardon, I meant blocked. I get the same output as in original post. In any case: root@pve:~# ps faxl | grep pveproxy 0 0 3372 3242 20 0 12732 1792 pipe_w S+ pts/3 0:00 \_ grep pveproxy

Cluster is up and running perfectly fine, full quorum, and /etc/pve is fully accessible... Yet the pveproxy service still blocks

Stuck with the exact same problem on 3 servers, however whenever it happens `pvesm status` seems to execute fine. This still is quite a problem. I also don't see any weird I/O wait times or whatever in the logs/nagios. Any ideas how to proceed?

Unfortunately no. We ended up ditching DRBD9 altogether in favour of a combination of snapshots and other live migration tools. To this day I would like to know what was causing this but at this rate, we might just wait for a bit and see if it gets fixed or it becomes a wider known issue. For...

Thanks @mir and @kobuki for your insights, I will look into it further and play around with various settings. For now, I've added a 120GB SSD to the servers, split the capacity in half meaning effectively 55.9GB for both cache and log. This resulted in an already quite remarkable increase to...

What would you recommend in terms of capacity split for ZIL (cache) vs. L2ARC (log)? Split the SSD capacity 50/50 or something, or is there something more optimal, and are there any places where the trade offs are documented?

For some reason, on 2 of my servers I'm getting incredibly slow IOPS and FSYNC per sec running pveperf Pproxmox 4, on a ZFS RAIDZ-1 cluster with 4 4TB WD Red's. root@pve:/# pveperf CPU BOGOMIPS: 15959.00 REGEX/SECOND: 743734 HD SIZE: 9921.49 GB (rpool/ROOT/pve-1)...

After a system crash I needed to restart a VM, call it ID x, after one of the other nodes in the DRBD9 cluster derped out. Now, node 1 derped out, and the VM was running on node 2, the issue being that restarting the VM on either node returns a KVM-error: Could not open...

Worked perfectly, thanks you so much. Time to donate a cup of coffee ;)
