Like the title says, I am moving from my Drobo 5N with 5 x 8TB spinners to the Linkstaion N1.

 

Since Drobo hid it's linux magic, I am not totally clear on setting up my N1 RAID.

I've set up RAIDs before - always on Windows Servers - all matching Dives blah blah blah.

 

So, here is my N1 opportunity.

 

2 x 1TB 2.5 SSD, 2 x 1TB M2, and 2 x 4TB M2.

 

How do I set it all as 1 big disk - with protection so I can lose a drive and replace it - where I can put shares etc.

 

Already have Plex running in Docker while testing with just 2 of the 6 drives I'll have in hand Saturday.

All help appreciated.  Prefer reading to Videos/YouTube

For that, and because they are not all the same size, you would need to assign them to the array with single parity, but note that TRIM is not supported with array devices, another option would be to create two pools, a mirror for the 4TB devices and a raidz pool for the other four SSDs.

Thanks,  I appreciate the info.

 

I think I will put 2 x 1 tb in a cache array , the 2 x 4TBs mirrored and put data there (mirrored seems safest for data integrity and probably the same with the other 2 x 1 tbs).  

 

So 1 zfs Cache array with 2 x 1tb, 1 mirrored data array with 2 x 4 tb, and 1 mirrored data array with 2 x 1 tb.

 

In the end I am giving up a 1/2 my drives for data safety I guess.

 

1 more question, if I am running all SSDs (as the N1 is built for) why do I need cache, everything is running at the speed of SSD?

You don't need cache, and you can just use pools (with v7.0.0)
