P2 test cases are still running. I will update you when they are finished. 1. From dmesg, we can see following lines. Could you check why it has these messages and if the messages impact the system? [ 3.341802] squashfs: SQUASHFS error: Xattrs in filesystem, these will be ignored [ 3.346056] unable to read xattr id index table 2. The kernel hasn't backport Michael's SRIOV performance improvement patches. The network performance is not expected. Here are the patches: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v5.18-rc2&id=37200078ed6aa2ac3c88a01a64996133dccfdd34 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v5.18-rc2&id=8d21732475c637c7efcdb91dc927a4c594e97898 3. It is failed to create raid 0 using below command. # mdadm --create /dev/md0 --level 0 --raid-devices 16 /dev/sd[abcdghijklmnopqr][1-5] mdadm: Defaulting to version 1.2 metadata mdadm: RUN_ARRAY failed: Invalid argument From dmesg, it has following lines: [ 235.830712] md: personality for level 0 is not loaded! [ 235.830733] md: md0 stopped. I see many raid related configuration is not set. Could you check the raid related and other configuration? # cat /boot/config-5.4.0-1076-azure | grep RAID CONFIG_RAID_ATTRS=m # CONFIG_BLK_DEV_3W_XXXX_RAID is not set # CONFIG_SCSI_AACRAID is not set # CONFIG_MEGARAID_NEWGEN is not set # CONFIG_MEGARAID_LEGACY is not set CONFIG_MEGARAID_SAS=y # CONFIG_SCSI_PMCRAID is not set # CONFIG_MD_RAID0 is not set # CONFIG_MD_RAID1 is not set # CONFIG_MD_RAID10 is not set # CONFIG_MD_RAID456 is not set # CONFIG_DM_RAID is not set CONFIG_BCM_SBA_RAID=m CONFIG_DMA_ENGINE_RAID=y CONFIG_RAID6_PQ=m CONFIG_RAID6_PQ_BENCHMARK=y [Test Case] Microsoft tested [Where things could go wrong] There should be little chance of regression given that these are config options.
