Issue Can't add a new domain/Project

J

jescayola

New Pleskian
Server operating system version
Debian 11.11
Plesk version and microupdate number
Plesk Obsidian v18.0.75_build1800260102.11 os_Debian 11.0
When I try to add a new domain with a basic configuration (blank website) it stops with an error like this (domainname.es is not the real domain):

"System user update is failed: Unable to create system user: vhostmng-structure failed: Cannot create directory /domainname.es: Operation not permitted
System error 1: Operation not permitted"

Before posting more data from the log, any clue?

Thank you!
 
Hi, @jescayola . Have you already tried the Plesk repair utility? If not, please try fixing the permissions/ownership with:

Code: 
plesk repair fs

If that doesn't help, additional log entries will be great. If possible, please able temporarily enable the debug mode in Plesk.
 
Hi! thank you for your reply!
I tried that and this is the output:
"

There are incorrect permissions on some items: /var/lock .......... [ERROR]
To see more details, run the command in the verbose mode: plesk repair fs -verbose

It found some error and I was asked to fix them, but at the end I have tried to create the project again with no success :(
 
Thank you. Please execute the following command and let us know if Mailman is present on the server:

Code: 
mailman --version
 
Hi again! Well, I tried plesk repair fs and got this at the panel.log:


[2026-02-09 09:45:26.500] 622181:69899ea67a2c6 ERR [util_exec] proc_close() failed ['/opt/psa/admin/bin/fsmng' '--set-ac' '/var/lock'] with exit code [1]

also, I have detected some vhosts folders with these permissions:
drwx-w--w- 2 root root 4096 Nov 28 06:53
or
drwx------ 2 root root 4096 Feb 9 09:53

They should't be there as I already deleted the projects from Plesk interface and I can't seem to be able to delete them manually as I get this error:
rm: cannot remove 'theproject.com/': Operation not permitted
I can't delete another project from the panel, which is already disabled.
Maybe this is related to what is happening?
 
Hi!
I tried that but the domains that I would need to delete don't show up in the list neither in the control panel nor using the SSH option... :(
 
I tried creating the new project again and check the log, this is what I got:

I suppose the filesystem is compromised somewhow and I will have to repair it manually, anyone has had to perform something like this? Thank you!
 
Morning!
I tried again to create or delete any folder inside /var/www/vhosts with the same result "operation not permitted". The log shows nothing at all with those attempts, but if I try to create a new project using the control panel I get this (among other lines):

[2026-02-21 09:06:07.298] 801170:6999676aaded8 ERR [panel] Task failed: id=20237, pid=801170, type=domain-create, clientRemoteAddr=79.116.11.49, current_stage=Hosting, domainName=fernandoubide.es, hostingType=hosting, isNewSubscription=1, ownerId=1, referrer=/smb/web/add-domain, renameTourAvailable=1, runTaskUnderLogin=jescayolacalvo, subscriptionId=1, error=PleskFatalException: System user update is failed: Unable to create system user: vhostmng-structure failed: Cannot create directory /fernandoubide.es: Operation not permitted

#13 /opt/psa/admin/plib/scripts/task-async-executor.php(6): Task_Async_Executor->execute()


These are the folder attributes:

drwxr-xr-x 5 root root 4096 Feb 21 09:13 www

and inside www

drwxr-xr-x 3 root root 4096 Jan 30 2025 cgi-bin
drwxr-xr-x 2 root root 4096 Feb 21 08:57 html
drwxr-xr-x 72 root root 4096 Nov 22 06:51 vhosts

I can actually create and delete within the www and html, but nothing in vhosts
Hope this helps to clarify and find a way to solve it!
Thank you!
 
Thank you. That looks right. Unfortunately, I cannot identify the issue despite all the details you provided. I would suggest opening a ticket with Plesk support for further investigation on your server. To sign-in and open a ticket please go to:
If you got your license from a reseller, your reseller is in charge of providing you with support. You can raise the inquiry with them and they can forward it to our team for further processing.

If the reseller does not provide support, here is an alternative to get support directly from Plesk:
