I forgot add that the R710 is the system I'm starting with since it isn't running anything at the moment. Probably followed by the CS24-SC and the DL360s.

I've been computing since the days of DOS and now think that it makes sense to virtualize a lot of the boxes I have since their hardware can do much more than they are currently doing. I have the following servers I would like to put to use: HP DL380 G5 dual x5460 16-32GB RAM (haven't upgraded...

Very interested in this answer myself as a lot of medical offices need this system design!

We should have local meetups. I would be willing to host one in Bay Area (San Francisco, CA) as my apartment complex has a community room we can use that has wifi. If there is interest in this, I can start a separate thread on it.

So should this work or not on older hardware like this? I have several g5 HPs and some Dell Rx1x series and 2950s that I'd like to use proxmox on and then everything else as VMs.

Are you running 2019 or 2016 like the OP?

Luckily all these tools also have a command line, so you can view dmesg, et al.

He mentions building a mirror in proxmox and then they disappear. I too think it is a hardware issue. There are a lot of good gui tools like parted magic. I'm happy to say the days of terrible gui frontends is gone as not everyone is confident with commandline, and there is risk if you...

It is odd that they only had issues after being configured like that, but I've seen weirder failures in my decades in IT, so I wouldn't rule out potentially bad drives or an extremely rare incompatibility or fluke issue. There's a wd drive checking program on the UBCD--that's where I would start.

I wouldn't necessarily blame it on zfs or proxmox--errors on drives can still break these things, and you don't know if the drives are 100% error-free yet.

With having tried formatting the drives in both proxmox and ubuntu, I would download the ultimate boot cd and use its hard drive tools to format your drives and then try formatting them using what you want to build your zpool.

$20 is an arbitrary number. At the rate ssds are dropping in price a 512GB nvme ssd will be $20 by Christmas, and worth nearly nothing by the time it wears out--and that was my point. There will also be version updates that may resolve extra writes, or increase them, or make them mandatory by...

Interesting. Are the drives smart enough to automatically know those are then 'spare' sectors?

Good idea. Thank you for the data point. One question though--how do you overprovision them to 50%? Do you have to use some sort of proprietary manufacturer's tool or is there a command that can be run?

I second this as modern (and even some not so modern) ssds will last years even with writes. And with the prices on these dropping all the time, you're spending a lot of time to save what eventually will be a $20 piece of hardware--not worth the time.

I wouldn't let the lack of native 10GBE sway you since you can always add a card. The performance of both seem pretty similar according to cpuworld: http://www.cpu-world.com/Compare/514/AMD_EPYC_Embedded_3000_3251_vs_Intel_Xeon_D_D-1541.html I think the biggest factor that I would be looking...

I'm researching proxmox and have the same question as the OP--does the pve or vm storage have the most io? I was initially thinking of putting pve on the ssd, but now maybe it seems the vm would benefit more. However, the vm(s) I plan to run have a sort of virtualization themselves so they...

I know this is an older thread, but what version of Proxmox did you install and did you do it bare-metal. Thank you in advance for any assistance. I have a z420 just like the OP that I'm thinking of using.
