drive migration guidance

[mr-hexen]

my current setup:

 

Parity - WD20EADS

Data1 - WD5000AKS

Data2 - WD5000AKS

Data3 - WD5000ADS

Cache - Seagate 160gb

 

unRAID Plus 4.7

addons: clean shutdown, transmission, unmenu, mover modifier (_ and sync), mail.

transmission is installed on /mnt/cache/.transmission

 

What I want to do is this:

assign   drive             change

Parity - WD20EADS >> no change

Disk1 - WD5000AKS >> no change

Disk2 - WD5000AKS >> no change

Disk3 - WD5000ADS >> cache

Cache - Seagate 160gb >> remove

Disk4 - WD20EARS >> new addition

Disk5 - WD20EARS >> new addition

Disk6 - WD20EARS >> new addition

 

in english, change the cache drive to the WD5000AADS as well as move the contents of the 160gb cache to this drive, add three WD20EARS.

 

data is only on Disk1 and Cache right now.

 

here's what I'm thinking the steps are.

 

1. stop array.

2. un-assign Disk 3 from the array.

3. recalculate parity and start array.

4. copy seagate cache to /mnt/disk3/   (what is the proper command to do this???)

4.1 tell user shares not to use cache.

5. un-assign seagate 160gb as cache.

6. assign disk3 as cache.

6.1 tell user shares to use cache.

7. remove seagate from system.

8. install the 3 new WD20EARS and assign as needed disk5/disk6/disk7.

 

 

do i have this right?

if it were me I would:

 

1. Run a parity check

2. Take screen grab of current drive assingments

3. Stop all apps that might be using cache drive

4. Use mc to copy contents of cache drive to disk3

5. Stop the array

6. initconfig the machine

7. assign drives where you want them to be

8. Start the array and calc parity

 

 

You will be without parity protection until this completes.

thanks Prostuff.

 

not concerned with lack of parity, only 50gB of data (build is only a few weeks old).

 

what is initconfig?

INITial CONFIGuration, got it, re-initialize array. thanks.

so started the switch over. Decided to retain the 160gb as my cache drive since its a single platter drive thats brand new. should be very reliable and low power for 7200rpm.

 

however, it has all been reverted back to normal, the icy dock MB973 i got was DOA in bay #3. would recognize my WD20EARS 25% of the time, and when it did I got DMA I/O errors constantly in the console.

 

RMAing it for a replacement, 1 more attempt, then I'm getting it refunded.

 

any other 3in2 cages people recommend that are short like the icy dock 973? this is (for now) going in a Gen1 Antec P150
