New Hard Disk - Best setup


Recommended Posts

Hi - I've just recieved 2 new hard drives (8TB each) and wondering the best way to incoperate them in my server, I've only been using Unraid since the start of the year so still getting my head around it - I'm on Unraid Plus.

 

Some of the drives are starting to get old and I would prefer to reduce the number of drives in the server. All drives have 2 backups on different servers. 

 

I use the server for for media and a few VMs so don't really want to rebuild the whole system

 

Originally I was going to remove a 2TB, 3TB and a 3TB drive and replace it with 1 8TB and then use the second as a back up.

 

my current setup is:

 

Disk 1    WDC_WD20EZRX-00D8PB0_WD-WMC4M0H9WRW2 - 2 TB (sdl) Used 1.27 TB Free 726 GB
Disk 2    WD1003FBYX-88_LEN_WD-WCAW30CRFVZ8 - 1 TB (sdk) Used 7 GB Free 993 GB
Disk 3    TOSHIBA_DT01ABA300_13P9ULWAS - 3 TB (sdg) Used 2.06 TB Free 942 GB
Disk 4    TOSHIBA_DT01ABA300_Z5OP3GBGS - 3 TB (sdh) Used 2.25 TB Free 747 GB
Disk 5    WDC_WD30EFRX-68EUZN0_WD-WCC4NNSYFXPP - 3 TB (sdi) Used 1.51 TB Free 1.49 TB
Disk 6    WDC_WD30EFRX-68EUZN0_WD-WCC4N0695182 - 3 TB (sdj) Used 1.30 TB Free 1.70 TB

Array of six devices 15 TB Used 8.40 TB Free 6.59 TB

Since you don't have a parity disk defined, I'd set a new config and assign one new 8TB as disk 1, remove the empty disk, and set the disks you want to keep sequentially after, followed by the disks you want to remove. Then rearrange the data either manually with rsync, mc, or you could use unbalance. Once the data is where you want it, set another new config and assign only the disks you are keeping.
