Hi Giovanni No, ultimately I never posted my findings, as there are too many variables at play when combining caching with Ceph, and even setups that benchmarked well didn't actually perform particularly well in our real world usage. We did run with bcache backed OSDs for a bit, it was fine...

Bearhntr your problem is very unfortunate for you, but doesn't seem to be anything related to the subject of my thread, which is having the web interface lockout as a security feature, rather than something being broken on your server.

OK so inspired by the certificate error that Chrome gives after a few days, I do have one option, if I run pvecm updatecerts --force then the generation a a new cert will cause Chrome to stop talking to the proxmox web server and so the session will time out in due course (albeit still not very...

Hi I'm trying to harden up security and one of the issues is that proxmox doesn't have a logon timeout - if I leave the proxmox tab open then if someone gains access to my session they will have access to proxmox (obviously I can try and remember to always close it but sometimes you get...

Hi all, Running a reasonably small proxmox and ceph deployment, four servers split across two buildings in our school, then a fifth witness server (which doesn't host any VMs/storage) in a third location. In order to sustain things in the event of failure, we run 4/2 copies on ceph, so any two...

Well, if you aren't using a proxy server then I'm presumably wrong, although a good tool for investigating is Telerik's Fiddler - it runs as a local proxy server so that you can see all communication going on between your web browser and the web server, in this case Proxmox. You might want to...

If you are obtaining new hardware anyway then it's a good idea to spin up a test cluster when that hardware arrives to test if the performance is sufficient before committing to production. I'm sure many people out there are running SQL servers on Ceph, although how well it works for you will...

Do you have a proxy server setup? I seem to recall that Firefox uses it's own proxy server settings, where Edge and Chrome will use the system proxy settings (from the 'Internet Options' widget). Most likely explanation to my mind would be that novnc uses a non standard port which the proxy...

No, but I did do a whole bunch of testing with bcache, lvm cache and lvm write cache on a ceph lab setup. Haven't quite got round to writing it up yet and posting... If you do have success getting opencas working would be very happy to add that to the benchmarks.

Contents of config.out look like the below. Given that pve-headers is installed any suggestions what I should try next? Is there another kernel header package? 1_append_bio.conf 2 1_bdev_nr_sectors.conf 1 1_bdev_lookup.conf 1 1_bdev_whole.conf 1 1_bd_first_part.conf X 1_bdget_disk.conf 2...

Has anyone had any success or got any pointers for installing OpenCAS on Proxmox 7? I'm trying to run some testing with it in my lab setup, on the no-subscription repo, latest version of proxmox. I've installed all the prerequisites (I think) - commands run so far are: apt install sed make...

Thanks for the reply - I did misunderstand it at first and had some interesting results which I will now report! I dug into the settings, ashift=12 was already set as I'd hope. The recordsize was set to 128k. I bumped it up to 512k, created a new virtual disk and repeated the test on that new...

Hi I've been doing a lot of reading and a bit of experimentation with Proxmox this week and have a bit of a strange situation, in terms of performance. I manage the network of a large school, and we've been using Hyper-V for a few years with Storage Spaces Tiered Storage local to our...
