UNIX for Dummies Questions & Answers

Hello.

On my family laptop, I have a directory named /local.
It is owned by root.
I want to create a sub-directory named documents ( /local/documents ).
I want to exclude exec for every body in that directory
I want every authenticated linux user can create a sub directory ( ie : /local/documents/openoffice ) and put in it any documents ( /local/documents/openoffice/WG3600-WriterGuideLO.pdf ) so that every authenticated linux user can read it. Only the owner can delete files that belong to him.
Any help is welcome.

If you have LVM in place there (and some free space in the VGs), then you could create new filesystem, then mount it under /local/documents with "noexec" option.

/local is sda13; 40Go; and is used at 25%
/my_multimedia is sda14; 60Go and is use at 25%

Is it possible to use part of each sda13 and sda14 to create a new disk with LVM. ?

Is it possible to use LVM on non-empty physical partition ( sdax ) ?

if not, I suppose that at the same time
1°) I must move /local, /my_multimedia somewhere and umount sda13 and sda14
2°) Create a Volume Group over sda13 et sda14
3°) Create 3 LVM logicals volumes : one for /local, one for /my_multimedia and one for /my_documents ( formerly /local/documents )
4°) format these new partitions
5°) mount the new partition
6°) Restore moved data

Any help is welcome

As far as I'm aware it is not possible.

So if not, I suppose that at the same time
1°) I must move /local, /my_multimedia somewhere and umount sda13 and sda14
2°) Create a Volume Group over sda13 et sda14
3°) Create 3 LVM logicals volumes : one for /local, one for /my_multimedia and one for /my_documents ( formerly /local/documents )
4°) format these new partitions
5°) mount the new partition
6°) Restore moved data

Could you confirm that procedure.

By the way it seems to be the same work if :
1°)move /local, /my_multimedia somewhere and umount sda13 and sda14
2°)delete sda13 et sda14
3°) Re Create sda13 and sda 14 with smaller size for /local; /my_multimedia
4°) create sda23 ( sda 15-22 exists) : for /my_documents ( formerly /local/documents )
4°) format these new partitions
5°) mount the new partition
6°) Restore moved data

Any comments is welcome

Both approaches will work for your current situation. Going with LVM has the advantage of being "future-proof". If you will for example leave some space in the VG, you will be able to create another filesystem if needed. You will also be able to shrink filesystems if it turns out that you need to create new filesystem and there is no free space in VG (but there is unused space on the filesystems created in that VG).

Thank you for taking times to help me.
