Hello Guys,

 

Here is what I am trying to do. I will be taking one of my current 3TB disks (disk1) from the array and use it as a cache drive and put another 4TB in its place. Currently the 3TB (disk 1) has one of my movies folder as well as the plex library folder in it. what would be the best way to accomplish what i am trying to achieve without loosing at least the (watched movies). So far I tried copying the PLex library folder to another location but I kept getting "permission errors". Pleas also keep on mind that I am not using parity still (if that makes any difference).

 

Thanks in advanced

 

 

You're somewhat defeating the whole purpose of UnRAID by not using a parity drive to make the array fault tolerant.

 

I'd add your new 4TB drive as parity; do a parity sync; then do a confirming parity check ... and THEN buy another 4TB drive and simply replace your 3TB drive with it => UnRAID will automatically rebuild the drive's contents onto the new drive (along with providing you with an extra TB of space) ... and then you can re-purpose your old 3TB drive as a cache.

 

Thanks for responding Garycase, Here is the rest of the story, I actually have already purchased 5x 4TB Segate Nas HDD of which one will be used for parity and the rest will be added to the array. My final setup will be as follows

- 1x 3TB Segate Baracoda (Cache)

- 1x 4TB Segate Nas HDD (Parity)

- 4x 3TB Segate Baracoda

- 4x 4TB Segate Nas HDD

- 1x 3TB WD Green

 

Thanks

 

 

Then the simplest way to do what you want is as I outlined -- add the parity drive first;  then after you have a parity-protected array, simply replace the 3TB drive with a 4TB drive and wait for it to rebuild.  Then you can add the remaining drives 

That sounds good except I am also trying to move my plex library file from "disk1" to the new Cache drive 

Get the system upgraded to parity and the drives upgraded ==> THEN work on configuration changes !!

 

All Done 

 

Thanks for your help garycase
