[How much RAM do you have installed in your unRAID server?]

32GB ECC. Overkill, but it's what the box came with. I usually use around 40% of it with Plex transcoding and a bunch of dockers.

Not sure it will, check after rebooting, if it doesn't you can use a script to enable it.

Next time I can, I will for sure. Went ahead and added it to a user script. Can't hurt it if the variable is already checked. This is why I love this community. Thanks!

Write cache for parity disk is disabled, you can turn on with:

 

hdparm -W1 /dev/sdX

  

Might go back to default after a reboot.

 

That single command bumped it up to 70MB/s. Much thanks. Any way to make it persist through a reboot?

[(SOLVED) Slow parity sync]

Hey all. I have an HP ML350p Gen 8 running Unraid 6.6.7. One thing I haven't gotten around to in the couple of months this system has been around is setting up parity. Right now, it's estimating 10 days for the initial parity sync at 4.5 MB/s. Read checks have passed at 97 MB/s in the past. I'm just trying to figure out why parity is grinding to a halt while everything else is performing flawlessly. Diagnostics attached.
