Good evening everyone!

Decided to get back into hosting a server at home, and dusted off my unRAID key, and bought a new-to-me server from work(For only a dollar!)

Specs:
CPU Dual 6240s xeons 18c/36t
RAM 8x8GB ECC RAM
10x Mix of 600/900gb SAS Enterprise 10k disks (Will be expanding this shortly, just need to get the WAF for a JBOD)
RAID card PERC H730 in HBA mode.

EDIT: I'm attempting to do an encrypted ZFS pool.

The issue I'm facing, is I'm getting extremely slow parity sync write speed. <10MB/s typically. It's been running for the better part of an hour with no ramp up. Would anyone be able to point me in the right direction of what I could possibly be doing wrong?

Attached is my diags.

Thank you for any help offered, and have a wonderful night/day!

There appears to be something else reading from the array, make sure all activity is stopped, you can also run the diskspeed docker test to see if all disks are performing normally.

Hey Jorge,

Hopefully unRAID pays you something for all the help you offer!

But this is a brand new array, nothing is configured, and that was the initial sync. I let it run it's course overnight, and it seemed to pickup a decent bit of speed finishing out at around 30MB/s, which is great, but these drives are decently old, and used in a retired DB server before being used by me, so read/writes were rather high on them. Had a bunch of errors on one disk(>2100) So thinking new drives are in short order.

I'd consider this to be closed. Thanks for the help though!

That still seems low, you may want to
