Summary0014090: "Asking for cache data failed" erors followed by drive being inaccesible with kernels > 3.10.0-514.21.2.el7.x86_64
DescriptionThis is brutal (daily loss of operability and possible data loss/corruption.) I'm surprised no-one else has reported :(

Occurs on all Centos 7.4 virtual machines I have running.

MS Hyper-V Linux Integration Services 4.2.3 installed in order to leverage replication through VSS (Using VEEAM I don't believe this can be done with built in LIS.) I also tried earlier versions 4.2, 4.2.2.

I am not 100% certain that this occurs without being triggered by replication but pretty sure it does. Will keep an eye on times.

I tried reverting kernels. Anything after 3.10.0-514.21.2 exhibits the same problem.

May have missed testing on kernel 3.10.0-514.26.1
Testing now.

3.10.0-514.26.1 is fine actually.

3.10.0-514.26.2 and anything after have this problem.

Uninstalled MS LIS and installed hyperv-daemons.x86_64
Issue remains.
