[SOLVED] How I can access to a partition?

Bourbon · 07-14-2016, 03:19 PM

Hi All,

My desktop machine has 2 HDD [UEFI]:

Code:

- /dev/sda = Windows 10
- /dev/sdb partitioned as (pics hereby attached):
/dev/sdb1 = swap
/dev/sdb2 = Linux Mint
/dev/sdb3 = Slackware
/dev/sdb4 = still empty

I have access from Slackware to Windows (/sda) but don't have access to Linux Mint (/dev/sdb2).
Please, what I can do to get access to Linux Mint from Slackware?

Code:

This is the /etc/fstab file:
/dev/sdb1        swap             swap        defaults         0   0
/dev/sdb3        /                ext4        defaults         1   1
/dev/sdb2        /boot/efi        vfat        defaults         1   0
#/dev/cdrom      /mnt/cdrom       auto        noauto,owner,ro,comment=x-gvfs-show 0   0
/dev/fd0         /mnt/floppy      auto        noauto,owner     0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0
tmpfs            /dev/shm         tmpfs       defaults         0   0

I know about the "mount" command, also found this thread:
http://www.linuxquestions.org/questi...tition-600700/
which clearly explains the process but am afraid to spoil something due the (for me) new "UEFI" HDD.

Thank you for reading

If you're info is good, your Mint is mounted at /boot/efi as shown in your fstab.

Just

Code:

 cd /boot/efi

to check that.

Perhaps a lsblk from Mint and from Slackware could help...

Your /etc/fstab is wrong. It sets the filesystem of /dev/sdb2 as vfat but it is should be ext4 as shown on your second pic. Also this partition should not be mounted as /boot/efi but as /Mint or something like that (create the directory /Mint as root first, then edit /etc/fstab).

Also seeing your fist pic /dev/sda1 is probably an EFI partition, and there is no reason to have a second one.

PS Your HDD has nothing special (it just has a GUID partition table in case of sda), UEFI designates the kind of firmware you have.

Does it have to be mounted all the time?

Hi All,

Thank you for your kind concern, the briefing here:

@ Tonus: - The command cd /boot/efi shows nothing, output here:

Code:

bash-4.3$  cd /boot/efi
bash-4.3$ lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 931,5G  0 disk

sr0     11:0    1  1024M  0 rom  
bash-4.3$

lsblk command from Linux-Mint after editing fstab on Slackware here:
# something wrong with fonts here

Code:

dominum@HP-Pro-3300-Series-MT ~ $ lsblk

@ Didier Spaier: - The new "fstab" here:

Code:

/dev/sdb1        swap             swap        defaults         0   0
/dev/sdb3        /                ext4        defaults         1   1
#/dev/sdb2        /boot/efi        vfat        defaults         1   0
/dev/sdb2        /boot/Linux-Mint        ext4        defaults         1   0
#/dev/cdrom      /mnt/cdrom       auto        noauto,owner,ro,comment=x-gvfs-show 0   0
/dev/fd0         /mnt/floppy      auto        noauto,owner     0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0
tmpfs            /dev/shm         tmpfs       defaults         0   0

I have been creating the directory /Linux-Mint under /boot then edited "fstab" file as above; it is mounted now but is'nt listed on Dolphin's left column, I have to go manually to /boot/Linux-Mint to see it (I did'nt work on files there but I can open them; maybe I have to change "1 0" with "1 1"?).
It's wrong the footphat /boot/Linux-Mint? - Needing to cancel and create the Linux-Mint folder under /mnt?
Talking about /dev/sda1, I don't know what I have to do there.

@ jefro: - Yes please, I should like to have access to Linux-Mint just clicking on the Dolphin's left column every time I use the computer as already possible when wishing access to removable hard-disk (VERBATIM) and Windows.

Hoping I don't forget any detail, the issue is almost solved now. I mean, I should like to see Linux-Mint listed on Dolphin.

Thank you once again for your kind help

Didier Spaier · 07-15-2016, 04:24 PM

I meant

Code:

/dev/sdb2        /Linux-Mint        ext4        defaults         1   0

not

Code:

/dev/sdb2        /boot/Linux-Mint        ext4        defaults         1   0

But as it wouldn't hurt to check the file system in /dev/sdb2 at boot time you could write:

Code:

/dev/sdb2        /Linux-Mint        ext4        defaults         1   2

So create a folder /Linux-Mint. then edit /etc/fstab accordingly.

Please read "man fstab" to get a better understanding.

Also, you do not have to do anything with /dev/sda1, that is the Windows recovery partition, as its label says (ripristino= recovery). There is no need to access it from Linux (neither from Windows unless you need to recover it if it is broken).

jefro · 07-15-2016, 09:47 PM

Side note.

I think I've read about this odd behavior in Dolphin before. Not sure where.

Bourbon · 07-18-2016, 02:38 PM

Well, having now access to the Linux-Mint partition even if it is not into the Dolphin left column I mark this thread as SOLVED.
Thank you Didier Spaier
