      What were you trying to do that didn't work?

       

      This is a follow up to the original issue https://bugzilla.redhat.com/show_bug.cgi?id=2139728 // https://issues.redhat.com/browse/RHELPLAN-138219

       

      It seems the problem has come back, but in a slightly different way. The live resize of a (data) disk in azure is not recognized at all by the OS without running a rescan of the scsi bus. I am suspecting this may be an issue on the HyperV side of things, rather than the kernel side of things because I can also no longer get it to work with kernel 4.18.0-477.10.1.el8_8.x86_64 which I had written down as a fixed kernel for the last issue

       

      What is the impact of this issue to you?

      Need for manual rescan of scsi bus instead of it happening automatically

      Please provide the package NVR for which the bug is seen:

      5.14.0-503.35.1.el9_5.x86_64
      4.18.0-553.47.1.el8_10.x86_64

      How reproducible is this bug?:

      Every time

      Steps to reproduce

      1. Live resize disk in Azure
      2. Observe nothing happens on OS level
      3. Run rescan-scsi-bus.sh (part of sg3_utils or just manually do it "echo 1 > /sys/block/XX/device/rescan" )

      Expected results

      Automatically notice changed disk size on OS level

      Actual results

      Disk size change only noticed after manual scsi bus rescan
