[SOLVED] Cache drive install 4.7

[Boost]

Hello all,

 

I recently built a 16TB(2TBx8 slots) unRaid server using version 4.7. Somewhere along the line I forgot to make room for a cache drive so all my sata slots are filled with drives.

 

I guess it defeats the purpose to use an IDE drive as a cache drive. Another option I thought of was to remove one of the drives from the array to use as a cache drive.

 

What led me to want to install a cache drive is that I would like to install sabnzb on my unRaid system and also came across an article that mentioned the performance gains that could be had.

 

Any thoughts and suggestions on how best to go about setting up this cache drive?

 

Thanks,

boost

you can use an IDE drive.  It will still be faster than writing directly to the parity protected array unless it is a really old drive.

One more Question,

 

Can I remove one of the sata drives from the array and make it the cache drive if I decide not to use the IDE drive?

Yes, you can remove a disk from your array, but them you must set a new initial disk configuration and calculate parity initially on it.

So, I'm assuming that I have to use unmenu to re-calculate parity?

 

This is what I have done thus far;

 

stopped array, shutdown unRaid server

unplugged one sata drive from the array,

power system on, logged into unmenu

Clicked "Check and correct parity"

Ok, I think I got it. After removing that sata drive, I did "initconfig" so the system rebuilds the new parity config with remaining drives.

Correct. You will have to reconfigure your shares also.

Great, thanks, I got it done!
