How to monitor storage replication after Storage spaces direct node reboot (ex. after updates)

Saturday, January 21st, 2017

Hi!

I have two node Storage spaces direct scenario and after updating and rebooting one of the nodes in cluster I need to wait storage operations to complete (yes I am updating this scenario manualy :)).

If you want to check the progresss of this synchronization / repair of Storage spaces just drop this in Powershell on one of the nodes:

Get-StorageJob | Select Name,IsBackgroundTask,ElapsedTime,JobState,PercentComplete,@{label=”BytesProcessed (GB)”;expression={$_.BytesProcessed/1GB}},@{label=”Total Size (GB)”;expression={$_.BytesTotal/1GB}} | ft

You should get something like that…

Remember – if you have Storage spaces direct in two-node scenario you SHOULD WAIT for this job to complete – if you reboot second node to soon your CSV will go offline! So keep calm and Powershell! 🙂

System x3650 M5 – M5210 controller jbod mode – invalid arguments

Recently I wanted to use disks connected to M5210 raid controller as JBOD…
My controller has also additional cache and battery pack and in this configuration you are getting the error “The requested command has invalid arguments.” when trying to Apply change to JBOD…

well… If you physical remove the cache from your controller…

…and a reboot… you will be able to enable JBOD mode…

…finaly in Windows – disk manager you can see your disks…

Important NOTE for those that would like to test Storage Spaces Direct technology that is comming with Windows Server 2016 (currently TP5)!

This will not work as BUS TYPE is still RAID and this is not supported – it should be SAS. The setup will fail at the step Enable-ClusterStorageSpacesDirect

The only solution is to buy a simple HBA as written here.

“…All SATA and SAS devices must be attached to a SAS Host Bus Adapter (HBA). This HBA must be a “simple” HBA, which means the devices shows as SAS devices in Windows Server…”
