problem was after VM reboot, not during the creation /dev/sdX is not persistent naming, so we modified the deployment process https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/9/html/man... Marek Dne 2024-08-21 v 10:05 marek napsal(a):
Hello,
I am creating VM, and disks on VM, and I am occurring a problem, where the logical names of the disks are probably not created / assigned sequentially.
This is the outcome that I would expect:
disk_name | logical_name -------------------------------- os_disk | /dev/sda vm.example.com_4 | /dev/sdb vm.example.com_3 | /dev/sdc vm.example.com_2 | /dev/sdd vm.example.com_1 | /dev/sde
However I have experienced on multiple occasions that the logical names are mixed, for example like this (see row 1 and 2):
disk_name | logical_name -------------------------------- os_disk | /dev/sdb vm.example.com_4 | /dev/sda vm.example.com_3 | /dev/sdc vm.example.com_2 | /dev/sdd vm.example.com_1 | /dev/sde
I have tried to add state: "present" and wait: true parameters for each disk, but this has not helped, and I am still facing the same problem.
ansible snippet below
any tips/advices where to dig?
