Critical updates for S2D and Hyper-V

Microsoft released a new update for Windows Server 2016 (14393.2580) that fixes a bunch of critical issues in S2D and Hyper-V (FCI) environments:

  • Addresses an issue that depletes the storage space on a cluster-shared volume (CSV) because of a Hyper-V virtual hard disk (VHDX) expansion. As a result, a Virtual Machine (VM) might continue writing data to its disk until it becomes corrupted or stops working. The VM might also restart and then resume writing data until a corruption occurs.
  • Addresses an issue that occurs when using multiple Windows Server 2016 Hyper-V clusters. The following event appears in the log:

    “Cluster Shared Volume ‘CSVName’ (‘CSVName’) has entered a paused state because of ‘STATUS_USER_SESSION_DELETED(c0000203)’. All I/O will temporarily be queued until a path to the volume is reestablished.”

  • Addresses an issue that may cause the creation of a single node cluster or the addition of more nodes to a cluster to fail intermittently.
  • Addresses an issue that occurs when restarting a node after draining the node. Event ID 5120 appears in the log with a “STATUS_IO_TIMEOUT c00000b5” message. This may slow or stop input and output (I/O) to the VMs, and sometimes the nodes may drop out of cluster membership.
  • Addresses an issue that may cause the addition of nodes to fail intermittently after creating a single node in a Windows Server 2016 Cluster. The error code is, “0x0000001e”.

This update also resolves the following issues:

It’s highly recommended to apply the update as soon as possible.

Microsoft MVP for the 5th time in a row

I’m delighted to announce that I have been awarded Microsoft Most Valuable Professional (MVP) 2018-2019 for the 5th consecutive year:

Microsoft MVP 2018-2019 | Roman Levchenko

I would like to thank my family for ongoing support and everyone of you who have supported me in any form during the last year. So, needless to say, I couldn’t have done the following without all of you:

# my first book was published

# a couple of technical reviews of the well-known books (details later)

# books translations and localizations for Microsoft Russia

# publications at the official Microsoft Blog

# social activities (sharing, forums and etc.)

# speaking at local events

# multiple blog posts (thanks for your reading and comments!)

P.S. I’d like to paste a new photo here…but my Award Kit is on it’s way :). And, as it’s a 5th award, I’m expecting a special accompanying “5 years” ring.  Stay tuned.

Update: Award Kit has been arrived! 🙂
