mahuan1688,
The documentation will be available shortly on our website, however, you can use the command below to create the disk:
Code: Select all
vdo create --name=vdo_dedup --device=/dev/disk/by-id/%DRIVE_ID% --emulate512=enabled --vdoSlabSize=2G --sparseIndex=enabled --activate=enabled --indexMem=0.25 --blockMapCacheSize=256M --deduplication=enabled --vdoLogicalSize=%Size%

ZFS is supported, however, there are no documents on VDO and ZFS configuration yet.

Where can I see if zfs is supported, when creating the device?
Last time said that the document will come out soon, how long will it take!

ZFS works as a back-end storage with VSA. Optionally, primary path is MDRAID still due to performance reasons.

By the way, is the documentation ready, about creating VDO devices!
In addition, I have two servers, servera and serverb. I would like to ask whether the witness disk is required for the high availability of the two devices, and where is the witness disk installed? Server a or server B, or add another server C and install it on server C. after the server a or B is down, they will take over each other automatically and the business will not stop.

Working on it.
Now let me answer your question.
Witness is required only if you build a failover cluster out of 2 Windows hosts. Learn more about Microsoft Failover Cluster quorum
https://docs.microsoft.com/en-us/window ... ter-quorum.
In a nutshell, you can go with 2 servers and a witness disk.
Actually, it takes some time for the resources to failover automatically (that's how Microsoft Failover Cluster works).

2-Node vSAN NFR on ESX
During the experiment, I allocated 27tb of space and set 80g of cache space. After all the configurations were normal, I shut down the host of a node. Then the virtual machine was damaged and did not take over automatically. The latest program 13586！

Could you tell me more about the experiment?
How exactly the virtual machine was damaged? Any specific errors added to this thread will be helpful. What do you mean by "take over automatically"?
Will be waiting for your answers.

Two vsans for vSphere A and B with HA shut down node A normally. All applications are not automatically linked to node B, and the virtual machine running on the storage is damaged and cannot be recovered ，back cache 80G

Are StarWind HA devices in sync now?
Please note that it is necessary to run FlushCacheAll.ps1 to flush all the cache for sure. Use the IP address of the server where StarWind Service is running.
You can find the script here C:\Program Files\StarWind Software\StarWind\StarWindX\Samples\powershell.
If you are an NFR user, please log a call with StarWind Support if you require any assistance.
