Add a new hard disk to Linux and create an LVM group

1. Take the virtual machine as an example, add a new hard disk to the virtual machine, create an LVM group, and use the new hard disk to hold the Oracle database files.

2. Fdisk-ll to see if the newly added hard drive is recognized, and the SDB has been identified.

3. # vcreate/dev/sdb (Create PV, equivalent to win will convert the base disk to dynamic disk)

4, # vgcreate Oracle_vg/dev/sdb (Create VG, create virtual volume group, no this concept in win)

5, # lvcreate-l +100%free oracle_vg-n oracle_lv (create LV,LV equivalent to the logical partition in Win)

6, use Lvdisplay to view the created VG and LV information.

7. # MKFS.EXT4/DEV/ORACLE_VG/ORACLE_LV (format created LV and formatted with EXT4 file system)

8. Create a directory and mount the LV

Mkdir/oracledata

Mount/dev/oracle_vg/oracle_lv/oracledata

9. Modify the/etc/fstab file and add a line at the end:

/dev/oracle_vg/oracle_lv/oracledata ext3 defaults 0 0

To automatically mount each time the reboot is carried out

10, assign the directory to the specified user, and give read and write permissions.

Chmod-r 775/oracledata (give directory Read and write permission)

Chown Oracle:oinstall/oracledata (Set attribution Group, user name: Oracle user group: Oinstall)
