Resolved Problem with /var/lock after upgrade

[Mister Lone]

Hi community,

I've got a problem after upgrade to Onyx when I try a fs repair :
"$ plesk repair fs -y -v

Checking Linux system files

There are incorrect permissions on some items: /var/lock .......... [ERROR]
- Incorrect type of /var/lock. Expected: symlink. Actual:
directory
Repairing incorrect permissions ................................. [2016-12-13 11:45:15] ERR [util_exec] proc_close() failed ['/opt/psa/admin/bin/fsmng' '--set-ac' '/var/lock'] with exit code [1]

fsmng failed: ERROR:Cannot fix %s: file exists and it is not a symlink"

Can someone help me ?

Hi Mister Lone,

Pls. DELETE the file "/var/lock" with the SSH - command ( logged in as user "root" ) "rm /var/lock", and re-run your plesk repair - command.

 

[Mister Lone]

Thanks for your answer, i've deleted the folder and rerun the plesk repair. It fixes the problem.

Cheers,

Hi again UFHH01,

It seems that deleting the folder corrupted the system... I've got new errors now :

Hi Mister Lone,

pls. note, that the file "/var/lock" is a SYMLINK to the folder "/run/lock", while "/run" is a SYMLINK to the folder "/var/run" which should normally being repaired/re-created, when running the Plesk repair with the option "fs". If, for what ever reason, this symlink was not re-created by the Plesk repair utility, pls. consider to check

stat /var/lock

AND

stat /var/run

Pls. check as well your mount - settings:

mount | grep shm

There should be following structure:

# ll /var/lock
lrwxrwxrwx 1 root root 11 Jul 25 11:05 /var/lock -> ../run/lock

# stat /var/lock
File: '/var/lock' -> '../run/lock'

drwxrwx--- 3 root lock-manager 200 Dec 14 04:45 lmlib

drwxr-xr-x 2 root root 40 Dec 14 09:10 plesk
drwxr-xr-x 2 root root 60 Dec 14 04:30 subsys

You can just re-create it manually if it is broken.

 

[Mister Lone]

That's exactly what I have.

But problem is still here :-/

Hi Mister Lone,

pls. give us more informations for investigations:

mount | grep shm

... and the information about your current operating system, pls.​

In addition:

mount | grep tmpfs

stat /dev/shm

stat /run/shm

 

[Mister Lone]

Hi UFHH01,

Hi Mister Lone,

pls add to "/etc/fstab":

tmpfs   /dev/shm    tmpfs   defaults    0 0

followed by:

mount tmpfs

Consider as well a complete reboot, to see that all mounts work as expected.

 

[Mister Lone]

Ok, now that works but all the websites hosted are now on the plesk default page :-/

Hi Mister Lone,

pls. note, that it really would help, if you create a SEPARATE thread for ( additional ) issues/errors/problems/questions not related to the current thread title.
Just keep in mind, that searching forum - users and as well users using search-engines, will be pretty much irritated, to get search- results, which have absolute nothing to do with the initial issue.

 

[Mister Lone]

Ok, thanks for your help.
But the problems wasn't before doing the steps you wanted me to do
