what am I doing wrong
Thank you

 

I am using a debian version of ovh server, I do not know if the installation process, automatically creates partitions, or is mounted
Can this be the problem?
How can I create and assemble them?
Thank you



ls -l /dev/disk/by-uuid
total 0
lrwxrwxrwx 1 root root 10 Apr 1 14:21 cbe73fc3-bff4-4bc5-8ba8-5ef4cc17db67 -> ../../sda1

 

Thanks till
I have been reviewing the configuration of my server in vps in ovh
And I think I can not use the hard drive as swap memory
I can delete the current partition and create 2 partitions, but I can not install the operating system on the big partition, and ovh formats them by default
This is normal?

# fdisk -u /dev/sda

Command (m for help): n

Select (default p): p
Partition number (2-4, default 2): 2

No free sectors available.

With this tutorial I solve it?
https://www.howtoforge.com/ubuntu-swap-file

When the server is restarted, will it have swap memory?
or
Do I have to repeat the process?
regards
Thank you

 

Hello
I have created the swapp memory as in this tutorial
Https://www.howtoforge.com/ubuntu-swap-file
And I have the fstab file

Nano / etc / fstab


/ Dev / sda1 / ext4 errors = remount-ro, discard, usrjquota = quota.user, grpjquota = quota $
/ Swapfile none swap sw 0 0

I do not have anything else

it is right?
