TLDR; want to swap hardware(use current hdd's) temp whilst i rebuild into a rack setup then swap back.

 

I recently purchased a ds4243 with 24 sas 600gb drives and a md1000 with caddies(i love ebay), a 12u open adjustable rack and a 4u rosewill case.

I currently have a x99 xeon 14c/24t system 3x ICY BOX IB-565SSK with 13 data and 2 parity and 2x ssd cache, a p2000, and LSI 9207 8i in my current build in a CM storm trooper case, i have an old optiplex 9020 sff i5-4570 16gb ram just sitting around.

 

What i want to do is rebuild my x99 in the 4u rack case and have my parity and ssd's in there and data drives in the ds4243, whilst I'm doing all this i want to temp use the 9020 and the md1000 as a make shift home to my plex server, i have a 9207 8e to connect to the das, so friends and family could still use plex.

 

option 1: Would i be better off starting a trial unraid while i do this update/rebuild, could i just copy my docker app data folders off the cache and on to another ssd for the cache and use my data drives and forgo the parity drives for now.

 

option 2: Use all my drives (i have a pic of what order they are in) and plug my current unraid usb and unpin any cores i have for the vm, and docker containers, into the dell and use intel qsv instead of the p2000 for plex and hope for the best.

 

Is there anything i may have missed all help appreciated

I'm got a bit lost about what you're trying to do in the middle, but if all you want to do is keep the HDD's and run Unraid on a different board while setting something else up you can just swap your unraid usb to that new hardware and then back again.  There's not a limit to types of hardware, just how many times you can write a licence to a key.  

 

I've swapped mine around a few times and it didn't matter.

 

Secondly, the HDD's don't actually need to be in the same order unless you've got a very strange (or possibly old) setup.  They assign to Id's which are specific to the drives.  I've swapped cables, drive locations and all sorts around many times and it always comes back.  This is normal for a modern linux distro.  Perhaps if you had an older unraid version installed before this feature was implemented and followed a path of upgrades I could see it being an issue, but that would be all.  (A longer term user of unraid may be able to clarify this further).

 

If they fit, I'd keep all your drive in the new system.  If they don't, you could configure the system how you want before moving it (unplugging the drives after so you don't get confused about what you disabled) and then install it / bring it up in the new one.

 

That's how I'd approach it anyway.  I'd leave the parity on, because you know when you move things around, sometimes things fail and you might need it.

 

Hope that helps.

For dual parity, the order matters.

i was after some info if i pulled my usb stick out of the current setup and put it into the dell 9020 and use my drives in the md1000 and would it boot just fine, i took a pic of the drives just so i knew what 2 are my parity drives if it lost what drives they were.

I then wanted to pull my current system down and rebuild it in a different case and have it rack mounted and the ds4243 attached for future hdd upgrades, at the moment i can not pre-clear a drive in the system if i needed to. I have another unraid build that i use as a home media player/lounge gaming and pre clear hdd's in that.

 

I was just guessing before i move the drives I would have to clear my pinned cpu for docker/vm and i would diable the vm (it only has all my steam library installed on it) i have as to not use core resources from the i5, i am running the 6.7.1 rc1 nvidia ver of unraid with a p2000 for plex h/w transcode which wont fit in the sff case of the dell so i thought intel quick sync vdideo might be able to handle that for the time being as i have upto 4 people streaming from plex of a night.

 

i hope that clears it up a bit, thanks

This statement is confusing in the context of this thread. The OP is talking about physical order of the drives, you are talking about logical assignments in Unraid.

 

Unraid doesn't care what order you connect the physical drives to the interfaces, it uses the drive ID to keep the logical assignments the same no matter where they are in the case.
