Good to know, I appreciate the help! Do you think ZFS is a reasonable alternative to using RAID here?
Using ZFS on Proxmox for couple of years under different workloads (home servers, productions at job), it is very good.
Just tune it as you need :)
Thanks a ton! I'm on the proxmox forums trying to figure out if I should stick with the H330 that came with the server and return/sell the H730 I got, or if I should use the H730. Seems there's a recent thread where they're figuring it out so I'll get to the bottom of it.
Imo get the H730 if it's financially reasonable. The passthrough is better supported in my experience. You can resell the H330 fairly easily.
Turns out they put the H730 in the server already so I never got an H330. I want to test the SMART data but it looks like the newer firmware should be fine.
Be aware! The dell R730 most likely comes with a raid controller which is not suited for ZFS. You need a true HBA instead. Some raid controllers do let you set them up in JBOD mode but it still is not suited for ZFS as you need a proper HBA and or a raid controller where you can flash the firmware to IT mode.
For ZFS storage and many apps and more Truenas scale might be interesting to you.
I've been reading that the updated firmware for the PERC H730 has no issues in HBA mode, and there's a thread from December in the Proxmox forums on using an H330 and H730 and they seem to work fine. I'm trying to get more clarification in that thread, but I'll also do some testing myself.
I run my 730xd with a H730 in HBA for months and Truenas has never had an issue.
It seems that the issues may be quite a bit deeper than they seem. That the cache on the H730 can cause subtle issues. Are you able to get SMART information from the H730 for the disks?
There might have been some firmware version messing with cache, ok. But I run latest firmware and yes, my SMART is clean and my scrubs are clean.
Ok cool. I need to update everything anyways so once I get around to that I'll test the H730 a bit but it seems that the newer firmware should be ok for ZFS
Take a look at the following topic. It is not just relevant for TrueNAS but ZFS in generel. https://www.truenas.com/community/threads/whats-all-the-noise-about-hbas-and-why-cant-i-use-a-raid-controller.81931/
