    Proxmox VE 5.0 Ryzen 7 1700X crashes daily

    Adjusting the c states and power save settings in the BIOS worked for me. I've had this issue since I first got Ryzen 1800X well over a year ago - really couldn't figure out what was going on (didn't matter Windows or Linux) - now it's sweet for several weeks. Thanks for the tips. :D

    disk move really slow

    I should add - I've moved back to EXT4 and the difference so far seems to be quite a lot. I would not be surprised at all to find out there is some kind of bug either in the code, or perhaps just in a default config somewhere that's causing this.

    disk move really slow

    This sounds exactly like the behaviour I've been seeing. It started when I started using ZFS. I gave up.

    LXC memory configuration

    I was reading up on swap just yesterday because I figure if memory is being paged via the host, it should be able to make it's own swap to supplement any required memory. Then I read (and I might agree) that swap in a guest can be managed better by a guest because it supposedly knows better...

    LXC memory configuration

    Just saying I am reading your thread with interest. No replies doesn't mean people don't want to help, just that we might not know how to! I haven't started a Journey to LXC yet, (only one test container) but plan on doing it soon. So this is great understanding for me. Hopefully someone...

    GlusterFS on new cluster?

    In spite of spending 25 years in IT and in infrastructure / applications space, somehow I never needed to manage large arrays. To that end, I've never bothered with IOPS calculations. However over the past few weeks due to performance issues, I've been reading up a lot about it. My 3 drive...

    What hardware do you suggest for homelab performance?

    Hi guletz, thanks for the reply, I appreciate you didn't have to. Actually, I originally had a different thread title, which I changed to this more clickbait oriented one because I realised people love making solutions for others but don't seem to speak to general design principles that much...

    What hardware do you suggest for homelab performance?

    For completeness running # zfs set sync=disabled rpool has made an incredible difference. However I still get IO delay of about 50-60% during file copy on a gigabit network with a three disk RAID0. Restoring a machine from backup still slows down the other machines enough to be very noticeable...

    [SOLVED] Poor I/O performance

    OK - depending on your work load and size of SSD-s you might want to up your time schedule then. In the disto's I've used it runs weekly, which may not be enough. If it isn't trimmed - you guessed it - performance suffers. A lot.

    [SOLVED] Poor I/O performance

    Sorry, this was the guy just before you about pveperf. You replied while I was replying to him.

    [SOLVED] Poor I/O performance

    openkiwi, basically there's two reasons - if you ever want to use ZFS and from what I've read using a consumer grade SSD will age very quickly with a VM workload. There is all sorts of information out there, all in pieces but in my small months running Proxmox I see this coming up over and...

    [SOLVED] Poor I/O performance

    According to the example at the very top of this thread, yes. Why not try it?

    [SOLVED] Poor I/O performance

    I wouldn't buy those from what I've read. Well depending on your config. I have two Samsung SSD's and have had to take them out.

    What hardware do you suggest for homelab performance?

    I found adding an old Hitachi 320GB 10k RPM drive as a SLOG, improved my FSYNC by about 2x. Given how old that is, seems like a flash based device is warranted. Looking at an Intel S3700 - the only one I can find is 200GB unfortunately which is a bit big. Would love it to be M.2 based but oh...

    What hardware do you suggest for homelab performance?

    So now I've disabled sync on my rpool because apparently if this speeds up fsyncs it means I would benefit from a fast external ZIL. Before root@proxmox:~# pveperf CPU BOGOMIPS: 114964.80 REGEX/SECOND: 2476069 HD SIZE: 5109.62 GB (rpool/ROOT/pve-1) FSYNCS/SECOND: 91.27...
