I have a new-to-me Dell 730xd that is excruciatingly slow for everything and need some help and guidance to improve its performance as I obviously have done it wrong.

 

Attached is a screenshot of my current setup. I understand my server is slow because almost nothing is using my SSD cache pool but hitting the disk arrays directly; my 4 NVME drives are being ignored, so sad. The reason for this is two-fold:

1. The Fix Common Problems plug-in would report an issue with the share being set to pool12TB but files existing on cache and needing to be moved.
2. When connected via NFS, I would receive messages about the file/directory had gone away, bad/changed fd (file descriptor?), and other nuisances making the share unusable.

Is there any way to be able to get the benefits of the SSDs on the two disk pools? I am happy to change the setup to different filesystems and/or configurations to get better performance.

That should only happen if the share is misconfigured.

Not recommended to use NFS with the mover, or you will likely get stale file errors, if possible use SMB, if not use a fast raidz pool.

For the share issue I have attached a screenshot of the configuration that was used. Can you advise what the misconfiguration would be?

All 3 pools are raidz1. Is that not not considered a fast raidz pool?

Thank you! That was maddening to work through.

That looks OK, post the diagnostics.

It will depend on the use case, raidz1 has the iops of one drive, so for some use cases striped mirrors will perform better.

Is something other than mirrors a possibility? I cannot currently afford to lose that much drive space.

This looks like a FCP bug, probably still doesn't allow for shares with pools as primary and secondary, recommend making a report in the existing plugin support thread.

What are you isng the pool for?

The "pool12TB" is for ISO torrent downloading and seeding along with general downloads.

The "pool14TB" is my Plex media.

 

I am currently rebuilding my library, which is the reason that speed is an issue. I expect to have >100TB on "pool14TB" upon completion of the rebuild.

For media, raidz should be fine, assuming there won't be many simultaneous users, if that happens, an HDD pool can have trouble with ransom access, and like mentioned, raidz pool has the same iops as a single HDD.

 

For seeding should also be fine, for torrent downloads, I would recommend using a single SSD formatted XFS, COW filesystems are not great for torrent downloading because they need to copy and write every block that has a change, which happens a lot with torrents, and then move the data to the main pool for seeding.
