    Anyone successfully running pfsense??

    What HW nics are you using? Right now I have uptime 10 days from last proxmox update and restart and pfsense has transfered ~435 GB without errors on any of the interfaces so I can say that pfsense can be stable on proxmox. I also have three vpn tunnels which I would know immediately if some of...

    [SOLVED] multiple kernel updates

    I have machine which was upgraded from old proxmox versions. Everything is vorking mostly fine now. But today I noticed that there are two kernel packages ready to be updated: Shouldn't there be just 4.15.xx in case of proxmox 5.2? I did upgrade system previously according wiki so all upgrade...

    [KNOWN ZFS PROBLEM] Freezing while high IO (only on host - not guest)

    I did upgrade to 0.7.6 on Friday and after 2 days of testing I didn't have any slowdown/freezing problems as with previous versions. I was able to do all backups including largest VM and everything run smoothly, no system load spikes. I will keep testing through week and report back if problem...

    [KNOWN ZFS PROBLEM] Freezing while high IO (only on host - not guest)

    Thank you. I'm trying to solve this directly with ZFS on Linux team as there seems to be more people with this problem even though it has been marked as fixed in 0.7.6 (and now moved to 0.7.7) (curiously lot of people reporting this are running Proxmox - that probably just because Proxmox is one...

    [KNOWN ZFS PROBLEM] Freezing while high IO (only on host - not guest)

    Sorry for bothering but could we gut update to full 0.7.6 now when it's fully released to actually have all the patches? Thank you

    [KNOWN ZFS PROBLEM] Freezing while high IO (only on host - not guest)

    Next observation: When IO gets high (I simulated high load with rsync) I took a look at dirty pages (after I stopped rsync because I noticed increasing system load again): cat /proc/vmstat | egrep "dirty|writeback" nr_dirty 59 nr_writeback 32 nr_writeback_temp 0 nr_dirty_threshold 904847...

    [KNOWN ZFS PROBLEM] Freezing while high IO (only on host - not guest)

Last one (around 200 GB in size) start slowing down server as usual but then suddenly I lost connection to server entirely, I left it over night but even after 10 hours it wasn't responding...

    [KNOWN ZFS PROBLEM] Freezing while high IO (only on host - not guest)

    I think that post #20 shows what is exactly happening to disc (I will try testing it again tonight). What I don't understand is that even when I try to operate with data on one pair of DATA SSDs io will always hit system SSDs. Right now I will also test to drastically lower ARC so far it was...
