LVM size in Linux avoiding to open documents in Libreoffice?

flavio.mesquita · October 23, 2018, 9:00pm

I’m having an issue while trying to open documents with Libreoffice writer, these documents were working fine up to a week ago, everytime I try to open a document now it gives error:
problem opening file

If I try to create a new one, it creates, but gives this error:
error creating files

I tried to update the Libreoffice package didnt solve, tried to completely uninstall and install the latest version didnt solve either. Checked the permissions for the user are ok, so i decided to look at the disk space. It gives me the following messages:

[root@localhost ~]# df -h

So, if there is available space as seen with the command df-h, why with the command pvs it says the /dev/sda8 has only 4M free? I’m working with other programs in the same directory without problem.
Tried to change permissions, putting 777 to everything, still no luck.

When you create an LVM volume, the corresponding disk space is allocated on the physical disk filesystem so that no other activity on the computer will “borrow” from it and damage LVM processing. This is why fdisk shows the partition as “full” because fdisk only considers the filesystem on the physical disk.

pvs scans inside the OS-filesystem allocated file to report what’s happening in the LVM layer and reports the LVM usage.

LO is compatible with ANY filesystem known to the OS. I’m working with LVM without problem. LO accesses files through high-level interface and the OS translates this into low-level primitives.

That said, the error messages alludes to insufficient user rights. You should check the permissions of the directory into which you create your files and the directory above. Check also which user/group owns the directories and the files. You may also bump into SELinux access control restrictions.

If you still can’t solve the issue, edit your question (do not use an answer) to provide more info about ls -l or ls -lZ for SELinux check.

EDIT (after your question edition)

File permissions did seem to be correct in your home directory. I suppose your documents are stored in Documents/ directory. Have you checked it?

Note: it is not a good idea to add “x” permission on files because it makes them executable. Remove “x” from your .sql “and” .log "files.*

@ajlittoz I save everything under Documents, just creating new subfolders under it. Is it possible that something that I installed on the computer changed Libreoffice permissions? It is installed under group/user: root/root, but as my Documents folder and everything under it has permissions to write and read and execute for owner, group and others, it should work.
On the last week I have installed Netbeans, Gfortran compiller, Intel fortran compiler, and GCC compiller.

@flavio.mesquita: it’s perfectly OK to install packages under root. LO doesn’t change permissions; it is dependent on the system: if access is enabled r/w, LO can read and write according to OS rules (using first user permissions, then group then others). Installing compilers has no impact on user (at least in principle) unless you explicitly change settings.

Check along LO private user directory in ~/.libreoffice/ and below.

flavio.mesquita · October 25, 2018, 5:39pm

@ajlittoz: LO has the same privileges as the other programs that are under /opt

@flavio.mesquita: I meant the LO-private directory in your home directory. This is where LO store user information, profile and settings. If it can’t access it, things go really bad. Pay attention to the dot preceding the name; it makes the directory invisible to ls -l. You need ls -al to see it.

flavio.mesquita · October 26, 2018, 11:12am

@ajlittoz: Ok, it was under /.config/libreoffice . It seems ok, anyway I changed the permissions on this folder and all subfolders, still doesnt work. I really dont see what can be going wrong. If it not a permission it is some folder that is full.
[root@localhost ~]# pvscan
PV /dev/sda8 VG ol lvm2 [77.78 GiB / 4.00 MiB free]
Total: 1 [77.78 GiB] / in use: 1 [77.78 GiB] / in no VG: 0 [0 ]
What I dont understand is that if the system is full, why other applications keep runn

ajlittoz · October 26, 2018, 11:19am

@flavio.mesquita: I compare with my computer. Your ol is full. Try to delete unused files or move some to other virtual volumes. Maybe LO requirement in temp files is rather high.
