DCE 9.1.1 – Backup Failures Caused by Kernel Hung Tasks

[efantino]

Following upgrades to EcoStruxure IT Data Center Expert 9.1.1, backups are consistently failing across all upgraded servers.

Kernel logs show repeated I/O stalls exactly when backups run:

Version 9.1.1 was intended to improve backup reliability, but in our environment it has made the situation worse.

Has anyone else seen this in 9.1.1?

@efantino,

That error message is an rsync error message (used for backups) that displays when there is an I/O problem with slow network disks.  I would recommend working through technical support for them to analyze further if needed to determine if the issue is a connection to the backup share or something else.

Kind Regards,

Cory

We ran into the exact same issue after the upgrade.  Opened a case weeks ago.  Just heard from support this morning and needed to get them some more information.  Support let us know that they have a large backlog, so it took longer to respond.
