Storage Space Direct - Storage Jobs taking too long

Question

_{Monday, September 16, 2019 8:12 PM}

Hi,

I have four node S2D cluster with 2019 OS. This is lab environment with SSD+HDD disks and 10Gbps network. Cluster is working fine, I have great performances but there is one issue that bothers me.

Every time I patch nodes, and I restart one of the nodes I have to wait for Storage Jobs to finish (so that data is synced). I know that I have to wait this out and I monitor this with get-storagejob command. When jobs finish, I continue updating other server nodes. What bothers me is time I have to wait for these jobs to finish. They can take more than 60-80min. 

Is there any way to speed this process up? I see that network and disks are not utilized fully when storage jobs are being done. I found online that this is intentionally throttled by Microsoft not to mess with VM performances. However, since this is Lab environment, I would love to speed this process up if possible, because in this way, patching takes to much time...

BR,

Soko

Hi,

Thanks for your question.

When S2D nodes patching, rebooting a node will cause the pool and virtual disk to enter a degraded state. And when the node comes back online, it will automatically begin a background Regeneration storage job. And you'll need to wait for storage jobs (mirror repair) to complete after each server is upgraded.

Wait for storage repair jobs to finish and for all disks to return to a healthy state. This could take considerable time depending on the number of disks and volumes of data. If there’re a large mount of volumes of data, this may take a long time for reblancing S2D of storage job after each node pacthing by default, even need more than hours.

Therefore, it’s a normal dehavior with larger than an hour of storage job after each node patching in your circumstances. We strongly recommended take S2D virtual disks offline before the nodes patching.

Here’s an article demonstrated best practices for patching S2D, please refer to it to a comprehensive upgrading for S2D.
