Is it okay if the partition types of physical volumes that belong to the same volume group differ when using LVM?

Issue

  • Is it okay to mix partition types of physical volumes when using LVM? For example, having a volume group consisting of two volume groups with partition types set to 83 and 8e:
 Device Boot      Start         End       Blocks      Id  System
/dev/sdc1         1             23497     188739621   83  Linux
/dev/sdc2         23498         41021     173158169   8e  Linux LVM

Resolution

  • This is fine when using LVM. Partition ID's are only required when the kernel needs to know how to identify the partition. However, with LVM, partitions aren't even required as a pvcreate can be ran on an actual block device, so a different partition type should not affect the volume group or physical volume in any way.
