Как переименовать / dev / sdax (разделы) в Linux

Я сделал раздел как /partна моей машине с некоторыми важными данными ...

Но я терпеть не могу это назвать ...

Я хочу четкое решение, чтобы решить его и изменить имя, например /test...

Как вы видите, это моя /etc/fstabинформация:

# /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda5 during installation UUID=a21a99c4-e5b4-4197-ac5e-80d0fab1f30c / ext4 errors=remount-ro 0 1 # /home was on /dev/sda6 during installation UUID=2e37d833-ca34-4fa7-a5d8-a4423a5af9bc /home ext4 defaults 0 2 # /part was on /dev/sda7 during installation UUID=47e6e0b1-0e57-4184-a378-375b9ce315c5 /part ext4 defaults 0 2 # swap was on /dev/sda1 during installation UUID=485e9f78-4dce-4404-af4e-f43985525264 none swap sw 0 0

Дело в том, что моя информация важна, и я боюсь манипулировать ею, не будучи уверенным ... Я хочу безопасное решение ...

Как это возможно?

заранее спасибо

  • Unmount the partition:

    # umount /part

  • Rename the directory after making sure it's not mounted:

    # mountpoint /part &>/dev/null || mv /part /best_name_ever

  • Edit /etc/fstab to replace /part with /best_name_ever

  • Remount the partition:

    mount /best_name_ever

The # is of course meant to represent your root prompt, not actual input to be typed in.

To test the safety of this solution or any other one on dummy data

The following instructions are (in part) stolen from Virtual Filesystem: Building A Linux Filesystem From An Ordinary File.

  • Create an ordinary file with a size of 20 MB (for example):

    $ dd if=/dev/zero of=dummy_fs bs=1k count=20480 # 20480 = 20 * 1024

  • Create an ext4 filesystem on your file:

    $ /sbin/mkfs -t ext4 dummy_fs mke2fs 1.42.5 (29-Jul-2012) dummy_fs is not a block special device. Proceed anyway? (y,n) y ... # Output of mkfs

  • Mount the filesystem image, create some dummy data on it and test the solution:

    # mkdir /tmp/testmount # mount -o loop dummy_fs /tmp/testmount # touch /tmp/testmount/ # Create dummy data # ls /tmp/testmount blah bleh lost+found # umount /tmp/testmount # mountpoint /tmp/sexy_name &>/dev/null || mv /tmp/testmount /tmp/sexy_name # mount -o loop dummy_fs /tmp/sexy_name # ls /tmp/sexy_name # to ensure your data is intact: blah bleh lost+found

================================================================================== In GParted, Unmount it, and then you change the 'Label', which affects the given name and mount point. So if I changed this partition label to 'Data', it would have the label/name 'Data', and the mountpoint would become /media/wmobbs/Data.

Labels work best without spaces, and any special characters.

I also could do it in command line: If that does not work, change these lines in your /etc/fstab:

# /part was on /dev/sda7 during installation UUID=47e6e0b1-0e57-4184-a378-375b9ce315c5 /part ext4 defaults 0 2

to:

# /part was on /dev/sda7 during installation - mountpoint changed to /test UUID=47e6e0b1-0e57-4184-a378-375b9ce315c5 /test ext4 defaults 0 2

You can edit the file by running sudo nano /etc/fstab, then applying the above changes, and saving with Ctrl+O.
You then need to run sudo mkdir /test to create the needed folder - note that the folder needs to be empty.
You have to reboot for any changes to take effect
