Linux: Modify the partition name created during installation

1. Modify the partition target

Change "/oracle" partition to "/dba" partition

1.1 The disk is partitioned during Linux Installation

For example:

Serial number	Disk device name	Partition name	Remarks
1	/Dev/sda3	/Boot	Pilot Partition
2	Tmpfs	/	Root Partition
3	/Dev/sda1	/Dev/shm	SWAP Partition
4	/Dev/sda2	/Oracle	Prepare to install oracle partitions

 

1.2Set"/Oracle"Change partition to"/Dba"Partition

After modification, the partition structure must meet the following conditions:

Serial number	Disk device name	Partition name	Remarks
1	/Dev/sda3	/Boot	Pilot Partition
2	Tmpfs	/	Root Partition
3	/Dev/sda1	/Dev/shm	SWAP Partition
4	/Dev/sda2	/Dba	Prepare to install oracle partitions

 

2. umount/oracle mount point

# Umount/oracle

3. Create/dba directory under the root directory

# Mkdir-p/dba

4. Modify the mount point information in the fstab file so that the new mount point is automatically mounted upon restart.

# Vi/etc/fstab

# #/Etc/fstab # Created by anaconda on Mon Jan 20 05:59:16 2014 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab (5), findfs (8), mount (8) and/or blkid (8) for more info # UUID = a4011859-9a90-4a1b-96d8-90403810ff20/ext4 ults 1 1 UUID = d27a474f-b2bb-461e-834e-a1b29dc9988b/boot ext4 ults 1 2 UUID = 8a2feb00003626-43d4-a463-16f07f00003ff/OracleExt4 defaults 1 2 UUID = 5cd77e82-5bf0-4ac4-b789-0b17118d6dfe swap defaults 0 0 Tmpfs/dev/shm tmpfs defaults 0 0 Devpts/dev/pts devpts gid = 5, mode = 620 0 0 Sysfs/sys sysfs defaults 0 0 Proc/proc defaults 0 0

 

Find the content marked in red above and change "/oracle" to "/dba". The changes are as follows:

# #/Etc/fstab # Created by anaconda on Mon Jan 20 05:59:16 2014 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab (5), findfs (8), mount (8) and/or blkid (8) for more info # UUID = a4011859-9a90-4a1b-96d8-90403810ff20/ext4 ults 1 1 UUID = d27a474f-b2bb-461e-834e-a1b29dc9988b/boot ext4 ults 1 2 UUID = 8a2feb00003626-43d4-a463-16f07f00003ff/DbaExt4 defaults 1 2 UUID = 5cd77e82-5bf0-4ac4-b789-0b17118d6dfe swap defaults 0 0 Tmpfs/dev/shm tmpfs defaults 0 0 Devpts/dev/pts devpts gid = 5, mode = 620 0 0 Sysfs/sys sysfs defaults 0 0 Proc/proc defaults 0 0

 

5Make the partition mount point take effect

5.1 temporary effect

# Mount/dev/sda2/dba

5.2 restart automatic mounting

Because the fstab file was modified in step 1, the new mount point "/dba" will be automatically mounted when the Linux system is restarted"

6. Data Retention

After the original "/oracle" directory is modified to the "/dba" directory, the data in the original "/oracle" directory will not be lost.
