If I change the split level of something, is there an easy way to distribute it across another disk.

 

Or my precise example. I have an array that is the following:

WD3TB-Red - Parity

WD3TB-Red - Disk1

WD3TB-Red - Disk2

WD BLACK 500GB - Cache

 

Both my my main disks in the array are approaching 70% full and I am looking to get another disk. When I get the new disk I want to spread the files from Disk1 and Disk2 on to Disk3.

 

I can MANUALLY do this, and it wouldn't be that hard. But my question is, is the mover script or anything like that smart enough to do this?

my apologies, I am using 5.0-rc12a

Changes to the split level, allocation scheme, or include/exclude settings for shares only impact writes AFTER the change => nothing is changed on the current disks.

Why?  There's no benefit to doing so.  If you simply want all 3 disks to be used, just change your split level to "most free" => and all writes will then be to the new disk #3 until the amount of space is equalized on the drives.

Mainly I want to do it because one disk is above 70% and will be close to 90% by the time my drive comes in

There's no problem at all with a drive being 90% full.  It has no impact on the performance of your array => no further writes will be done to that drive (unless you set the allocation method to "fill up");  and read performance isn't impacted at all by how full the disk is.

 

Alrighty! Thanks for the tip.
