00:00:06,540 --> 00:00:07,373
- In this video

2
00:00:07,373 --> 00:00:09,930
I will show you how to
make mounts persistent.

3
00:00:09,930 --> 00:00:11,970
So, in order to make mounts persistent

4
00:00:11,970 --> 00:00:13,560
there's this configuration file

5
00:00:13,560 --> 00:00:16,415
and the name is /etc/fstab,

6
00:00:16,415 --> 00:00:17,700
in /etc/fstab

7
00:00:17,700 --> 00:00:19,140
You can provide

8
00:00:19,140 --> 00:00:20,580
the names of your devices

9
00:00:20,580 --> 00:00:24,390
and you can tell them where to mount.

10
00:00:24,390 --> 00:00:27,420
So I just created my sdb1

11
00:00:27,420 --> 00:00:29,610
and I want to mount my sdb1

12
00:00:29,610 --> 00:00:31,500
on the directory files

13
00:00:31,500 --> 00:00:33,000
do not create persistent mount

14
00:00:33,000 --> 00:00:36,030
on mnt because really the purpose of mnt

15
00:00:36,030 --> 00:00:38,430
is to have

16
00:00:38,430 --> 00:00:42,150
mounts that are temporary for testing.

17
00:00:42,150 --> 00:00:45,090
So the third column is where
I'm specifying the file system

18
00:00:45,090 --> 00:00:47,010
ext4 in this case,

19
00:00:47,010 --> 00:00:48,570
in the fourth column,

20
00:00:48,570 --> 00:00:50,490
if you have any specific mount options

21
00:00:50,490 --> 00:00:51,630
you put them in there

22
00:00:51,630 --> 00:00:53,670
in column number five and six

23
00:00:53,670 --> 00:00:55,860
you just put zeros.

24
00:00:55,860 --> 00:00:57,390
In the past they were important.

25
00:00:57,390 --> 00:00:59,160
Nowadays, column five and six

26
00:00:59,160 --> 00:01:02,010
should just contain a
zero and that's enough.

27
00:01:02,010 --> 00:01:04,650
And this will make sure that if I reboot

28
00:01:04,650 --> 00:01:05,580
the new partition

29
00:01:05,580 --> 00:01:07,590
will automatically be mounted.

30
00:01:07,590 --> 00:01:10,230
Now, if I may give you an advice

31
00:01:10,230 --> 00:01:14,670
use mount -a after editing /etc/fstab

32
00:01:14,670 --> 00:01:17,400
because mount -a is
going to mount them now.

33
00:01:17,400 --> 00:01:19,590
And if anything is preventing the mount

34
00:01:19,590 --> 00:01:21,720
from happening successfully,

35
00:01:21,720 --> 00:01:22,980
you get an error message.

36
00:01:22,980 --> 00:01:26,370
As you can see, mount
point does not exist.

37
00:01:26,370 --> 00:01:29,610
And at this point, it's
very easy to fix the error.

38
00:01:29,610 --> 00:01:33,810
I'm just using sudo mkdir /files
to create the mount point.

39
00:01:33,810 --> 00:01:37,293
And if I do my mount -a
again, now it is successful.

40
00:01:39,000 --> 00:01:41,400
If you don't do the mount -a to test,

41
00:01:41,400 --> 00:01:43,500
you might get in trouble while booting

42
00:01:43,500 --> 00:01:45,150
and in a booting environment,

43
00:01:45,150 --> 00:01:48,420
if your mount is not
happening in a successful way

44
00:01:48,420 --> 00:01:51,030
it's becoming a lot more complex.

45
00:01:51,030 --> 00:01:53,520
Let's finish by verifying the mount.

46
00:01:53,520 --> 00:01:56,163
If I type mount, the latest mount

47
00:01:56,163 --> 00:01:57,450
that you have just added

48
00:01:57,450 --> 00:01:59,670
is always listed on the last line,

49
00:01:59,670 --> 00:02:00,693
as you can see.

50
00:02:01,620 --> 00:02:04,780
You can also use sudo findmnt

51
00:02:04,780 --> 00:02:06,330
where findmnt as you know

52
00:02:06,330 --> 00:02:09,780
is showing you the file system structure

53
00:02:09,780 --> 00:02:11,940
with the mounts.

54
00:02:11,940 --> 00:02:13,230
So for any,

55
00:02:13,230 --> 00:02:16,200
any directory that is
mounted on a different device

56
00:02:16,200 --> 00:02:17,320
findmnt will show you

57
00:02:18,210 --> 00:02:20,038
or lsblk.

58
00:02:20,038 --> 00:02:22,320
lsblk is showing it

59
00:02:22,320 --> 00:02:24,360
from the perspective of the block device.

60
00:02:24,360 --> 00:02:27,420
So here we can see that
dev sdb1 has been mounted

61
00:02:27,420 --> 00:02:29,310
on slash files.

62
00:02:29,310 --> 00:02:32,970
And finally, you can also use df -h

63
00:02:32,970 --> 00:02:33,870
which is showing it

64
00:02:33,870 --> 00:02:36,120
from a disc usage perspective

65
00:02:36,120 --> 00:02:36,953
where we can see

66
00:02:36,953 --> 00:02:38,080
that sdb1

67
00:02:38,940 --> 00:02:41,010
is on a five gigabyte disc

68
00:02:41,010 --> 00:02:44,520
and it has used 28 kilobyte in total.

69
00:02:44,520 --> 00:02:45,810
That sounds reasonable.

70
00:02:45,810 --> 00:02:48,930
All of these help you
to verify your mounts

71
00:02:48,930 --> 00:02:49,763
and that's it.
