OL8: LVM - adding PV to VG and limitations

edited Mar 6, 2025 11:46PM in Linux Operating System (MOSC) 4 commentsAnswered

Hello,
we have Oracle Linux 8 system.
We are using Logical Volume Manager (LVM) for File Systems.

We found limitations about Oracle Linux in: https://docs.oracle.com/en/operating-systems/oracle-linux/limits/#topic_gz4_wls_3tb
But there are no document about limitations about LVM.

At the moment we have one PV in VG:

  • storage LUN (1,8TB)
  • the system recognized it as disk /dev/sdb
  • we created primary partition /dev/sdb1 (type: Linux LVM) on whole disk /dev/sdb
  • we created PV on partition /dev/sdb1
  • we added PV to VG (named ora)
  • we created xfs file systems (logical volumes): /u01 (80GB), /oradata (600GB), /oraarch (300GB), /orabackup (500 GB) in this VG

Howdy, Stranger!
