/web1/tmp/ full (cannot delete, cannot empty the folder)

Hello,
my website is giving below error:

Code:

Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/www/clients/client1/web1/tmp)

From what i've understood this can be due to:
1) lack of disk space
2) lack of inode
doing a df -h rules out option 1. So i'm assuming tmp is simply full. However i cannot delete the content (tried numerous commands to delete very large folders, none are working for my case). I tried to archive the folder (renaming it) and creating a new one, but "permission denied" even when sudo. Is there a way to do it via ISPconfig admin interface ?
My other idea is to override php.ini settings and choose a new folder for session.save_path (probably a folder i create in web1/web/ as i cannot mkdir in /web1/, but that will probably be a security issue).

Do you have any recommendation please ? i'm really stuck here...

Thank you

 

Verify with

Code:

df -hi

file system has free inodes.
You could paste here (in CODE tags) the output of df -hT. I am confused by your stament "tmp is simply full".

 

Hello @Taleman :
df -hi

Hi @till,
are you talking about "hard disk quota" in ISPConfig ? if yes it is set to -1
Below is the error message i get, mentioning global /tmp folder

Code:

Warning: Unknown: open(/var/www/clients/client1/web1/tmp/sess_gb70hvjaea38auukfboad859l4, O_RDWR) failed: Permission denied (13) in Unknown on line 0

Warning : Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/www/clients/client1/web1/tmp) in Unknown on line 0

Thank you

 

But that is is my issue: i cannot delete the files inside this folder. I cant even list it, it takes way too much time. And i cant delete the folder.
ls -l /var/www/clients/client1/web1/

Code:

drwxr-xr-x  2 web1 client1       4096 Aug 20  2017 cgi-bin
drwxr-xr-x  3 root root          4096 Apr 27 12:55 home
drwxr-xr-x  2 root root          4096 Apr 28 04:26 log
drwx--x---  2 web1 client1       4096 Aug 20  2017 private
drwxr-xr-x  2 root root          4096 Apr 24  2020 ssl
drwxr-xr-x  2 root root    1065357312 Apr 11 22:14 tmp
drwx--x--x 40 web1 client1       4096 Mar 31 06:40 web
drwx--x---  2 web1 client1       4096 Aug 20  2017 webdav

 

so basically, i need to run this cmd ? prefer to ask as i dont want to delete all my site by mistake

Code:

sudo find /var/www/clients/client1/web1/tmp/ -type f -delete

 

Why sudo? Log in as user of that website, that user can not delete files not belonging to that website. Small help at least, and it is better use root privileges only when needed.
Otherwise that command seems OK, just leave out the sudo.

 

thanks, it seems to be working fine now
