Lab: Manage Basic Storage
I have tried several times to created disk using parted as per the instructions given. Until I create a 2GB backup partition and reboot the partition remains as created.
After creating swap and reboot the partition switches from /dev/sdb1 to dev/sdc1. I understand this happens because of the boot order.
lab grade command displays this as fail as it does not find /dev/sdb1 associated with mount point.
Before reboot:
[root@serverb ~]# lsblk -f

├─sda2 vfat FAT16 7B77-95E7 191.4M 4% /boot/efi

Should I be concerned?
