Hi,

do you have Sync=disabled in ZFS / ZPOOL settings?
If not, this can cause the slow speed ...

Betreff: [OmniOS-discuss] Fibre Target problems

I have a Supermicro X7DWN+ based server with 24 x 4Tb SAS disks on a LSI 
6G IT mode hba.

After configuring a bunch of 10Tb Luns and presenting to a Win2012 
server, write is very slow < 6 Mb/sec, and writing causes the Fc link to 
drop repeatedly.
Reads reach about 400Mb/sec.

OmniOS version is r151006_057.

I've tried two different 4G and an 8G QLogic adapters, via switch or 
direct, but there is no change in behaviour. Only 1 HBA and path.

The odd thing is the exact same hardware and os setup (fct, zpool etc.) 
works well with OI or Solaris 11/11, with writes getting around 4-500 
Mb/sec.
I had to start with OI147 and work up, as the later text installer is 
very buggy. Upgrading OI with qlt installed fails.

I'm at a bit of a loss as to a likely cause.

Anyone have any pointers ?
