Linux System Ext File system

Partition formatting (Linux File system creation): (assuming that the partition you need to format is /dev/sdb1)

1. Differences between the ext2 file system and the ext3 file system:

Ext2 does not support the log file system, does not produce log files,ext3 will produce log files, the log directory is:

/var/log.

2. create a file system partition:

Mke2fs/dev/sdb1

The default is to create the ext2 file system, if you want to create a ext3 file system, you need to use the parameter -j:

Mke2fs-j/DEV/SDB1

3. File system detection:

E2FSCK/DEV/SDB1: Detects sector errors, logical partitioning errors, and so on.

E2fsck-p/dev/sdb1: Detects errors and automatically fixes them.

4. View partition format:mount

5. view File System specific information:

Tune2fs-l/DEV/SDB1

Change the time of automatic detection:

Tune2fs-c 30/dev/sdb1: automatic detection after mounting

Tune2fs-i 30d/dev/sdb1: test after the day

6. Label Related:

one of the messages printed when executing the command tune2fs-l/dev/sdb1 is Filesystem volume name, which

is the volume label of the partition, used to indicate the purpose of the partition.

Specifies the volume label for a partition:e2label/dev/sdb1 wjt-data(www-data as the volume label)

Find partitions by volume Label:Findfs label=wjt-data
