Hi !
how to mount automatically and permanently a partition without requesting the root password every time I want to access in.
the partition is ext4.
thank you friends.

Hi!

- Go to the Mageia Control Center / Local Disks / Manage disk partitions: https://doc.mageia.org/mcc/4/en/content/drakdisk.html
- "you can switch to the hard disk you want to work on by selecting the correct tab (sda, sdb, sdc etc)."
- Click on the partition you want to automatically mount
- Click on Mount point
- Type the path you want to use to access the content, typically: /mnt/my_drive, and OK

Is this your partition on a local drive and permantantly available to the system?

You can also take another approach as explained in viewtopic.php?f=41&t=5148

If you take the approach as suggested by Symbioxy, keep https://wiki.mageia.org/en/Mageia_4_Err ... rrect_UUID in mind and be sure to add the option "nofail" for that mount as otherwise system boot will fail if this partition cannot be mounted during boot.

before reading your post I tried modifying fstab file and the catastrophe happened
this is exactelly what i'm suffring of and i'm not expert.
here is the content of the old fstab file ( not sure about the line i modified):

# Entry for /dev/sdb4 :
UUID=c660d5ca-ce0d-48d6-bb52-e21a5036f33c / ext4 acl,relatime 1 1
# Entry for /dev/sdb3 :
UUID=4f5cb9a8-a42c-4fad-8edf-1f33ab91e603 /home ext4 acl,relatime 1 2
# Entry for /dev/sda1 :
UUID=5BA5202220F01E0C /media/windows ntfs-3g defaults,umask=000 0 0
# Entry for /dev/sda5 :
UUID=cbc2090b-bafe-4ea7-9604-8767212f925e /var/ ext4 defaults 1 2 (here is the line i tried to modify and get it back)
none /proc proc defaults 0 0
# Entry for /dev/sdb5 :
UUID=2962d6a6-6b9d-4984-8b78-6e0e92e0b121 swap swap defaults 0 0

I added this thing at the end

Code: Select all: umask=000 0 0

and when i got the message you spoke about, i get back the line as it was.
but nothing changed, and i don't know what i have to do.
plz help me because I don't want to reinstall the system, it is full of applications and history of my skype discussions and more and more.

Well, when you are in the mergency shell, simply edit fstab with vi /etc/fstab and remove the umask=000 bit.
In vi, x key and Del key do the same. If you're done, press Esc :wq and enter to save the file.
You can also use any other non-graphical editor, e.g. nano or mcedit or emacs or whatever you like.

FWIW, which ext4 partition do you want to automount? /dev/sda5 ( /var ) ?
As you seem to have added the umask=000 bit for an ntfs partition ...?

In any case, you can also comment out the complete offending line from /etc/fstab by prepending it with a # sign.

At the end reboot and report back.

first of all thanks, I comment the line and the system works again
I have linux mint beside mageia and I did the modification via text editor, but mageia is my prefered distribution.
so, what should I do to resolve the mistake I did ?
thanks again

Best describe which partition you want to mount, and post the exact contents of your current /etc/fstab and the output of

Code: Select all: lsblk -fl

as root

hi and sorry to be late,
I would like to mount sda5, and here is the contenent of fstab as root

Code: Select all: # Entry for /dev/sdb4 : UUID=c660d5ca-ce0d-48d6-bb52-e21a5036f33c / ext4 acl,relatime 1 1 # Entry for /dev/sdb3 : UUID=4f5cb9a8-a42c-4fad-8edf-1f33ab91e603 /home ext4 acl,relatime 1 2 # Entry for /dev/sda1 : UUID=5BA5202220F01E0C /media/windows ntfs-3g defaults,umask=000 0 0 # Entry for /dev/sda5 : # UUID=cbc2090b-bafe-4ea7-9604-8767212f925e /var/ ext4 defaults 1 2 none /proc proc defaults 0 0 # Entry for /dev/sdb5 : UUID=2962d6a6-6b9d-4984-8b78-6e0e92e0b121 swap swap defaults 0 0

and the output of the command line lsblk -fl as root as well :

Code: Select all: NAME FSTYPE LABEL UUID MOUNTPOINT sda sda1 ntfs 5BA5202220F01E0C /media/windows sda2 sda5 ext4 stock cbc2090b-bafe-4ea7-9604-8767212f925e sdb sdb1 sdb2 ext4 bf44d1a6-55bc-4fab-84e5-03de10c76cae sdb3 ext4 home_of_mageia4 4f5cb9a8-a42c-4fad-8edf-1f33ab91e603 /home sdb4 ext4 mageia4 c660d5ca-ce0d-48d6-bb52-e21a5036f33c / sdb5 swap 2962d6a6-6b9d-4984-8b78-6e0e92e0b121 [SWAP] sdb6 ext4 50605965-c3b7-4cc6-aee7-44d6b7a63992 sr0

thnaks.

Please remove the trailing slash from the fstab entry.

Can you please show the output of

Code: Select all: mount -t ext4 /dev/sda5 /mnt ls -al /mnt

Totally apart from that, please keep in mind that you still would need to copy/sync over the content that is currently in /var to your new /var partition.

Code: Select all: total 44 drwxr-xr-x 8 root root 4096 Dec 29 20:48 ./ drwxr-xr-x 21 root root 4096 Dec 30 18:23 ../ drwxr-xr-x 5 root root 4096 Dec 29 01:19 cache/ drwxr-xr-x 7 root root 4096 Dec 29 01:19 lib/ drwx------ 2 root root 16384 Mar 17 2014 lost+found/ drwxr-xr-x 2 root root 4096 Dec 29 20:48 nmbd/ srwxrwxrwx 1 root root 0 Dec 29 01:17 proftpd.sock= drwxr-xr-x 11 root root 4096 Dec 29 20:48 run/ drwxrwxrwt 2 root root 4096 Dec 29 01:17 tmp/

and about what did you say :

i didn't understan that, sorry.

So the manual mount is OK. If you edited the fstab and removed the trailing slash, you can now remove the # sign at the beginning of that line, it will be mounted on next boot.

For your question: You currently have a running system where /var is on the / partition, and it already contains some files from your running system.
If you now mount /dev/sda5 as /var all the files in that directory from your running will be over-mounted and effectively hidden away.
You need to take care to replicate the current content of /var to the new /dev/sda5 partition.
But you can also simply try if it works like you want to do it and then report back.

when I removed # from that line I couldn't boot and I got this message :

Sorry, but there has been a problem starting your graphical display.

In order to debug your problem we will automatically switch to a text-based login screen from where you can login as the root user and run the "drakx11" utility to configure your graphical display.

and I go back to that line and put # again.

You're missing at least /var/log and also /var/lock symlink on the new sda5 partition. Also /var/run on your new partition is a directory, whereas it should be a symlink to /run.
Hence my previous hint:

This is what /var looks like here, from a clean Mageia 5 installation:

Code: Select all: ┌─[doktor5000@Mageia5]─[12:49:22]─[~] └──╼ ls -al /var total 32 drwxr-xr-x 1 root root 148 Dec 21 16:40 ./ drwxr-xr-x 1 root root 176 Dec 6 19:50 ../ -rw-r--r-- 1 root root 163 Dec 6 19:15 .updated drwxr-xr-x 1 root root 150 Dec 21 16:40 cache/ drwxr-xr-x 1 root root 8 Dec 6 19:18 db/ drwxr-xr-x 1 root root 0 Oct 31 19:47 empty/ drwxr-xr-x 1 root root 0 Oct 17 19:59 games/ drwxr-xr-x 1 root root 676 Dec 31 04:02 lib/ drwxr-xr-x 1 root root 0 Oct 31 19:47 local/ lrwxrwxrwx 1 root root 11 Oct 31 19:47 lock -> ../run/lock/ drwxr-xr-x 1 root root 1000 Dec 31 04:02 log/ lrwxrwxrwx 1 root root 10 Oct 31 19:47 mail -> spool/mail/ drwxr-xr-x 1 root root 0 Oct 31 19:47 nis/ drwxr-xr-x 1 root root 0 Oct 31 19:47 opt/ drwxr-xr-x 1 root root 0 Oct 31 19:47 preserve/ lrwxrwxrwx 1 root root 6 Oct 31 19:47 run -> ../run/ drwxr-xr-x 1 root root 94 Dec 6 22:03 spool/ drwxrwxrwt 1 root root 2082 Dec 30 22:15 tmp/ drwxr-xr-x 1 root root 22 Dec 21 16:40 www/ drwxr-xr-x 1 root root 0 Oct 31 19:47 yp/

You could so something like

Code: Select all: mount /dev/sda5 /mnt rsync -av --dry-run --log-file=rsync.log /var /mnt

and see the rsync ouuput what it wants to copy to your new sda5 partition.
