Non-native block size

Post by erico.bettoni »

After upgrading to 9.3 my pool started to show the following message:

Code: Select all

  pool: tank1
 state: ONLINE
status: One or more devices are configured to use a non-native block size.
	Expect reduced performance.
action: Replace affected devices with devices that support the
	configured block size, or migrate data to a properly configured
	pool.
  scan: scrub repaired 0 in 6h4m with 0 errors on Wed Feb 11 20:35:55 2015
config:

	NAME        STATE     READ WRITE CKSUM
	tank1       ONLINE       0     0     0
	  raidz1-0  ONLINE       0     0     0
	    ada0    ONLINE       0     0     0  block size: 512B configured, 4096B native
	    ada1    ONLINE       0     0     0  block size: 512B configured, 4096B native
	    ada2    ONLINE       0     0     0  block size: 512B configured, 4096B native
	    ada3    ONLINE       0     0     0  block size: 512B configured, 4096B native
	    ada4    ONLINE       0     0     0  block size: 512B configured, 4096B native

errors: No known data errors
Does replacing each disk with it's .nop equivalent will help with performance? Is it possible to do it?

What i found was that even if the disk is using non native it is best to follow this process and set it up to use 4K.
I was given directions to this page on the chat.

Since it is an existing pool i have no idea if you can even fix it in place.
