StarWind Software

Hi,

I have the following scenario:

2 nodes starwind VSAN free setup and running as HA pair. The imagefiles are on a RAID 10 consisting of 4x 6TB SAS HDDs. I need to add more HDDs now and add additional space to the imagefiles. However the Avago-Controller doesn't allow to Migrate the RAID 10 (see https://www.broadcom.com/support/knowle ... tab=search ).

I was wondering, if it can be done the following way instead:

- shutdown starwind-service on node 1
- add 8x 6 TB HDDs as additional RAID10 to node 1
- moving all data from the old small RAID10 to the new bigger RAID10 (this raidgroup is only used for the starwind imagefile, OS is on different raidgroup)
- removing the old small RAID10 and changing the driveletter of the new RAID10 to the driveletter of the old small RAID10
- starting starwind-service and waiting for the sync to complete
- then doing the same procedure with node 2
- once everything is synced again using the powershell skript to resize the starwind-imagefile

Could it work this way or is there something that could bite me when doing it this way?

Thanks in advance,
Holger

Holger,

Basiсally the described procedure is valid from the point of view of StarWind operations. They cover the major steps to be done.

Hi Boris,

thank you for your reply. Moving of Data on the first SAN is in progress (1.5TB of 10TB already moved). I'll let you know, if it worked out fine in the end.

Great. Keep us updated.

Node1 migration worked out really well. Node2 is scheduled for the next weekend.

Thanks again for a great product!

Nice to hear that. Let me know how the remaining part of migration works.

I'm happy to report back that everything worked out like expected. Due to the more drives/spindles/heads in the new RAID-group I now get >2 GByte/s read write inside a VM running on the vsandatastore (even while a lot of other VMs are still running). It was 1,6 GByte/s before with the smaller RAID-Group.

Very nice!

hoba,

Great to hear it worked as expected. Hope this information helps the community as well.
