cacheMode=none never works I tried it in my lab and it actually worked. HA with no cache is created. #cacheMode = completes build and sync processes but I still get image file with write-back enabled. It also works (device with no cache is created). See my script below param($addr="192.168.13....

Happy it works now. Please note that small amount of Write Back cache will not improve performance, yet, brings the risk of full syn closer. Consider trying running systems with no cache. Thanks yaroslav, but you see in my most recent post, I found that commenting out the cache fields "worked&...

Greetings, Glad it worked! Write-back cache is associated with additional complexities. True, enabling it gives more performance, yet, it requires RAID card BBU and UPS to run smoothly. Furthermore, when terminated the full synchronization is inevitable (see more at https://knowledgebase.starwindso...

Just comment the cache fields out. One other question - I have 2x Truenas arrays (all 7.2krpm spinners in mirrors/raid10) each providing 1x 4TB thick iSCSI LUN to the VMware cluster. Each Starwind vSAN node has 1x 16gb boot drive and 1x of the 4TB LUNs attached via RDM - no other disks or cache dis...
