[Touch-packages] [Bug 1996958] Re: [Azure] 18.04 - /by-path/ has the same path
** Description changed:
[Impact]
- Azure 18.04 has issue with /dev/disk/by-path/ has the same path name when vm
has multiple disks.
+
+ * The PATH_ID for SCSI disks on Azure/Hyper-V might not be unique
+with the systemd/udev version in Ubuntu 18.04 LTS (Bionic Beaver).
+
+ * This cause issues on applications that require unique PATH_IDs;
+for example Veritas Dynamic Multi-Pathing (DMP).
+
+ * The fix introduces changes to PATH_ID format/values for VMBUS,
+which would break stable names/links, so it must be an opt-in.
+
+ * The kernel command line option 'udev.new_vmbus_path_id' (boolean)
+can be used to opt in to (different) unique PATH_IDs.
+
+ * It's not used by default (i.e., no behavior change by default).
[Test Plan]
- 1. launch 18.04 on azure
- 2. add extra disk to #1 vm
- 3. check the path
- xtrusia@test-canonical:~$ udevadm info --name=/dev/sda | grep ID_PATH
- E: ID_PATH=acpi-VMBUS:00-scsi-0:0:0:0
- E: ID_PATH_TAG=acpi-VMBUS_00-scsi-0_0_0_0
- xtrusia@test-canonical:~$ udevadm info --name=/dev/sdb | grep ID_PATH
- E: ID_PATH=acpi-VMBUS:00-scsi-0:0:0:1
- E: ID_PATH_TAG=acpi-VMBUS_00-scsi-0_0_0_1
- xtrusia@test-canonical:~$ udevadm info --name=/dev/sdc | grep ID_PATH
- E: ID_PATH=acpi-VMBUS:00-scsi-0:0:0:0
- E: ID_PATH_TAG=acpi-VMBUS_00-scsi-0_0_0_0
+ 1. Launch an Ubuntu 18.04 VM on Azure
+ 2. Add extra disks to the VM
+ 3. Check the disks PATH_ID for (non-)unique values
+ 4. (Opt-in for the fix with kernel cmdline option; repeat 3.)
+
+ * Before:
+
+ $ lsscsi | grep /dev/sd
+ [0:0:0:0]diskMsft Virtual Disk 1.0 /dev/sdc
+ [0:0:0:1]diskMsft Virtual Disk 1.0 /dev/sdd
+ [1:0:0:0]diskMsft Virtual Disk 1.0 /dev/sda
+ [1:0:0:1]diskMsft Virtual Disk 1.0 /dev/sdb
+
+ $ for sd in /dev/sd?; do \
+ udevadm test-builtin path_id /block/${sd#/dev} \
+ 2>/dev/null | grep ID_PATH=; \
+ done | sort | uniq -c
+ 2 ID_PATH=acpi-VMBUS:00-scsi-0:0:0:0
+ 2 ID_PATH=acpi-VMBUS:00-scsi-0:0:0:1
+
+ * After:
+
+ Opt-in mechanism:
+
+ $ cat
