I´m trying to set up a 2-node HyperV Cluster with Server 2016 and I´m using the CreateHA_2.ps1 script to create the disks. The servers have identical hardware configurations: I´ve got seperate 1Gbit management, 1 Gbit heartbeat and 2x 10Gbit synchronization NICs. The underlying disk is a NVME SSD.
Now here´s what I don´t get: when I create the disk, the initial synchronization is VERY slow. I´m talking 30Kbit/s over a 10Gbit NIC. I´ve done some testing with the SSD and the 10GBit NICs and found that all of them work at their intended speeds.
Altough I can always create a tiny disk, let it synch and then resize the disk to their needed size, I´m worried that at some point the disk wants to do a full synchronization again, and then I´d have to wait a week for it to finish. Is the initial synch really that slow or did I mess up somewhere?
Here´s my CreateHA_2 Script settings:
Code: Select all
#common
$initMethod="Clear",
$size=20000,
$sectorSize=512,
$failover=0,
#primary node
$imagePath="My computer\V\starwind",
$imageName="SSDIMG",
$createImage=$true,
$storageName="",
$targetAlias="HV02TargetSSD",
$autoSynch=$true,
$poolName="pool1",
$syncSessionCount=1,
$aluaOptimized=$true,
#cache wb, none
$cacheMode="none",
$cacheSize=0,
$syncInterface="#p2=192.199.1.30:3260,192.199.2.30:3260",
$hbInterface="#p2=192.199.10.30:3260",
$createTarget=$true,
#secondary node
$imagePath2="My computer\V\starwind",
$imageName2="SSDIMG",
$createImage2=$true,
$storageName2="",
$targetAlias2="HV03PartnerSSD",
$autoSynch2=$true,
$poolName2="pool1",
$syncSessionCount2=1,
$aluaOptimized2=$false,
$cacheMode2=$cacheMode,
$cacheSize2=$cacheSize,
$syncInterface2="#p1=192.199.1.20:3260,192.199.2.20:3260",
$hbInterface2="#p1=192.199.10.20:3260",
$createTarget2=$true
)
Thanks in advance!
