I'm not sure if the title actually depicts my question, but I will try to explain. I have seen everywhere it is mentioned to create a partition of type LVM (8e) and then create logical volume with lvcreate. My question is, what if I create logical volume using lvcreate with non-LVM (83  Linux) disks/parition? I have actually created one so it is possible without changing it to LVM (8e) but I wonder what's the disadvantage of doing this? Is there anything/feature I won't be able to do using this way? Thank you, I hope the question makes sense.  Edit: Just to demonstrate my point with an example: # fdisk -l /dev/sdb   Device Boot      Start         End      Blocks   Id  System/dev/sdb1               1         132     1060258+  82  Linux swap / Solaris/dev/sdb2             133         394     2104515   83  Linux/dev/sdb3             395         656     2104515   83  Linux/dev/sdb4             657        1044     3116610   83  LinuxNote all sdb[234] are type 83[root@localhost ~]# pvs  PV         VG          Fmt  Attr PSize PFree   /dev/sdb2  vol_group01 lvm2 a--  2.00g 52.00m  /dev/sdb3  vol_group01 lvm2 a--  2.00g  2.00g  /dev/sdb4  vol_group01 lvm2 a--  2.97g  2.97g[root@localhost ~]# vgdisplay -v  vol_group01    Using volume group(s) on command line    Finding volume group vol_group01  --- Volume group ---  VG Name               vol_group01  System ID               Format                lvm2  Metadata Areas        3  Metadata Sequence No  5  VG Access             read/write  VG Status             resizable  MAX LV                0  Cur LV                1  Open LV               0  Max PV                0  Cur PV                3  Act PV                3  VG Size               6.98 GiB  PE Size               4.00 MiB  Total PE              1786  Alloc PE / Size       500 / 1.95 GiB  Free  PE / Size       1286 / 5.02 GiB  VG UUID               3lw7zo-rIb1-Px1v-qn5Q-FErx-eFAp-QvTosm  --- Logical volume ---  LV Path                /dev/vol_group01/Log_Vol01  LV Name                Log_Vol01  VG Name                vol_group01  LV UUID                Z6FMzG-WHFS-Z8iQ-gnps-DqkM-oJtc-kPupmq  LV Write Access        read/write  LV Creation host, time localhost.localdomain, 2013-01-19 21:13:58 +0000  LV Status              available  # open                 0  LV Size                1.95 GiB  Current LE             500  Segments               1  Allocation             inherit  Read ahead sectors     auto  - currently set to     256  Block device           253:2  --- Physical volumes ---  PV Name               /dev/sdb2       PV UUID               5IFORy-K475-xgYl-w7wL-ILA8-B4Ib-e6RobL  PV Status             allocatable  Total PE / Free PE    513 / 13  PV Name               /dev/sdb3       PV UUID               v4wc0X-16P2-x1cY-A9Pu-Dl3W-Us1N-A26EBp  PV Status             allocatable  Total PE / Free PE    513 / 513  PV Name               /dev/sdb4       PV UUID               L4uHEc-0Fnt-BLIa-9T5v-0IxP-o8PX-diQx5N  PV Status             allocatable  Total PE / Free PE    760 / 760
