Re: [Samba] Not enough storage space error

Hello Andrew,

From the day one, we set the log level to 3. Log size is really huge. However, I did not see some thing very interesting and related to this error. It is all to do with user login, information, etc. Should I have to increase the log level to get more info?

One thing we noticed. When we restart the samba-ad-dc service, it allows us to add new users, add new computers to domain, and even move the user from one OU to another. However, from last two days, at around evening (around 4:45 PM), samba all of a sudden cuts off all users from domain and even fails to list the domain controllers in RSAT. If we restart samba-ad-dc, it starts working properly.

Now we need to see, what is that event that is causing this cut off all of a sudden? Is it a shear coincidence? Or is it something to do with the large number of PCs are now getting added from different places? Incidentally, we use the same domain admin account (limited administrator) to add PCs to domain. Is this causing some problem?


Thanks & Regards,

Anantha Raghava

We are using Samba AD DC (Version 4.6.5) on CentOS 7.3. We have two
servers with BIND9 DNS and all are working just fine.

Today, when we attempted to move couple of users from one OU to
Windows RSAT reported /*"Windows cannot move object. Ther*//*e
not enough storage space*//*"*/.
I wouldn't take the error string literally.  There are too many layers
of mapping going on.  LDAP does not contain such an error, so think of
it as a bad translation.

Our servers have 300 GB Storage more
that 270GB is free on the storage. At the moment we have added about
1000 users and about 450 computers into domain. Overall, we will add
about 7500 users and equal no of computers to domain. I also noticed
that RSAT lost the connection to domain all of a sudden. However,
when I
restarted the samba-ad-dc service, it reconnected. I am able to add
computers and new users into domain. But moving the user from one OU
another is throwing above error.

I believe the DB is a 32 bit one and should support upto 4 GB. When
checked in /usr/local/samba/private folder the size of smb.ldb file
about 4.1 MB and rest of the ldb and tdb files are around 1 MB in

Now, how do I correctly check the current DB size? Is the above error
strange behaviour? How do we fix the above error?
Turn up the logging on the AD DC and see what the real error and error
string is.
