Comment on What is a good multirole server setup for a racked server?
kylian0087@lemmy.world 3 months agoBe 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.

Take a look at the following topic. It is not just relevant for TrueNAS but ZFS in generel. truenas.com/…/whats-all-the-noise-about-hbas-and-…
