Hello All,

 

So I wanted to test unraid before I bought it but I came across a problem that just made me unable to test unraid. Since there is a limit of 3 devices attached I thought I could get away with just testing with only the pcie ssd but unraid sees it as 4 disks each 60GB (the ssd is advertised as 240GB) so there is no way for me to test it. Now that is not really a problem because I can just test with a different disk but the problem is the licensing.

I was planning on buying the Plus license with 12 device limit but the setup im planning is 10 normal disks and 1 pcie ssd but as the pcie ssd is seen as 4 disks it will be going over that limit which forces me to buy the PRO license if I want to use the PCIE SSD. Is there anything I can do about this?

 

My second question: If I make the PCIE SSD (with 4x 60GB) and a normal SSD 240GB cache drives would it be a bad idea? Is it better to just have 1 normal 240gb ssd?

 

EDIT: The PCIE SSD: OCZ-REVODRIVE3 X2 240GB

Is it seen as one disk or four disks at the Bios level?  Are there existing partitions on the disk that need to first be removed?  In particular NTFS partitions on a cache disk often seem to cause problems for some reason.

It is seen as one 240gb disk in the bios and there are no partitions

I believe that SSD internally is in practice 4 x 60GB SSDs in RAID0, so that’s probably why Unraid sees it as 4 devices.

Is there something I can do to make it look like 1 drive? If not is it safe to use the 4 x 60GB in my cache?

I think that you’d have to ask LT to include the driver in the kernel, if there is a driver.

 

If not is it safe to use the 4 x 60GB in my cache?

 

Should work fine, just like a 4 disk cache pool, obviously it will count as 4 devices.

 

All right thank you for your help!

 

I got a different question now tho:

 

Do you have to install a VM on a cache pool or can I install it on a dedicated (for example a SSD) drive?

 

Cause I have 3 different SSD's now:

 

1 PCIE SSD 240GB (800/200 MB R/W)

1 SATA Crucial mx100 240GB (500/300)

1 SATA Samsung 850 EVO 500GB (550/500)

 

If I install it on a cache pool of those 3 drives will the performance just be of the slowest drive? (500/200 essentially)

 

 

Sorry for all these questions but i'm new to this and I don't have all my parts yet (no delivery on new year and stuff) so I can't really test it fully yet

 

EDIT: Also will a VM take the space it has or the space you assigned?

You can install a VM anywhere you like!

 

If you want to install it on a SSD that is not part of the unRAID array then the Unassigned devices plugin can help with managing such a drive.
