00:00:06,960 --> 00:00:09,630
- In the previous video
you've learned about EXT4.

2
00:00:09,630 --> 00:00:11,400
Now let's talk about XFS,

3
00:00:11,400 --> 00:00:14,580
which is the default file
system on Red Hat Linux.

4
00:00:14,580 --> 00:00:18,750
Mkfs.xfs is used to
create an XFS file system.

5
00:00:18,750 --> 00:00:20,759
And different utilities are offered,

6
00:00:20,759 --> 00:00:24,600
each having a name that starts with xfs_.

7
00:00:24,600 --> 00:00:25,860
If you want to have an overview,

8
00:00:25,860 --> 00:00:28,743
just use XFS underscore
and tap completion.

9
00:00:29,610 --> 00:00:33,245
Xfs_admin is the common utility
that sets default options,

10
00:00:33,245 --> 00:00:37,710
like the file system label
for instance, or a UUID.

11
00:00:37,710 --> 00:00:38,733
Let's check it out.

12
00:00:41,460 --> 00:00:42,293
All right.

13
00:00:42,293 --> 00:00:45,210
Mkfs.xfs - - help.

14
00:00:45,210 --> 00:00:47,490
Just to show you the different options.

15
00:00:47,490 --> 00:00:50,580
And here you can also see
that different options

16
00:00:50,580 --> 00:00:54,987
are available and same
story applies as for EXT4,

17
00:00:54,987 --> 00:00:57,843
you'll hardly ever use
any of these options.

18
00:00:58,738 --> 00:01:03,738
The only option that is
required is dev sdb whatever.

19
00:01:05,070 --> 00:01:06,330
The device name where you want

20
00:01:06,330 --> 00:01:08,910
to create your XFS file system.

21
00:01:08,910 --> 00:01:09,840
And there we go.

22
00:01:09,840 --> 00:01:12,270
The XFS file system has now been created.

23
00:01:12,270 --> 00:01:13,500
You can also see the options

24
00:01:13,500 --> 00:01:16,050
that have been used in order to do so.

25
00:01:16,050 --> 00:01:18,894
For an overview of
everything that you can do,

26
00:01:18,894 --> 00:01:23,894
type xfs, dap dap, for the
specific XFS utilities.

27
00:01:25,140 --> 00:01:27,658
XFS does have a couple of utilities

28
00:01:27,658 --> 00:01:32,193
that allow you to manage the
advanced features of XFS.

29
00:01:32,193 --> 00:01:35,160
Like XFS quota for instance,

30
00:01:35,160 --> 00:01:38,970
which allow you to set file
system space limitations

31
00:01:38,970 --> 00:01:42,690
or XFS copy, which is specific alternative

32
00:01:42,690 --> 00:01:45,570
to the copy utility that
works more efficiently

33
00:01:45,570 --> 00:01:48,708
in an XFS environment.

34
00:01:48,708 --> 00:01:52,789
Now how about xfs info on dev sdb2?

35
00:01:52,789 --> 00:01:55,740
That is just printing the information

36
00:01:55,740 --> 00:01:57,630
from the file system superblock.

37
00:01:57,630 --> 00:01:59,580
So the generic properties.

38
00:01:59,580 --> 00:02:02,343
XFS admin is convenient as well.

39
00:02:04,170 --> 00:02:05,580
Use minus minus help,

40
00:02:05,580 --> 00:02:08,430
even if it's telling you that
this is an illegal option.

41
00:02:08,430 --> 00:02:10,860
It'll print what you can do.

42
00:02:10,860 --> 00:02:14,460
And here are the options,
of which minus uppercase L

43
00:02:14,460 --> 00:02:17,220
and minus uppercase U
are the most common ones.

44
00:02:17,220 --> 00:02:18,808
We'll talk about these later.

45
00:02:18,808 --> 00:02:23,808
Just as a final test,
mount dev sdb2 on slash mnt

46
00:02:24,127 --> 00:02:26,160
to check that we can mount it.

47
00:02:26,160 --> 00:02:27,450
And yes, we can mount it.

48
00:02:27,450 --> 00:02:29,973
So we are in business
with the XFS file system.
