LDAP

Hi,

I have open-ldap server configured just to give e-mail addresses to Outlook users.
It's a small database with about 30 entries
In opend-ldap data folder (/var/openldap-data) I have some files, listed below:

-rw------- 1 root root 24K 2008-05-30 13:36 __db.001
-rw------- 1 root root 35M 2008-05-30 13:36 __db.002
-rw------- 1 root root 321M 2008-05-30 13:36 __db.003
-rw------- 1 root root 2.3M 2008-05-30 13:36 __db.004
-rw------- 1 root root 352K 2008-05-30 13:36 __db.005
-rw------- 1 root root 24K 2008-05-30 13:36 __db.006

__db.003 has 321Mb space.

What are these files? Can I delete that file or gzip it??

Chances are they're sparse files. What does "ls -ls" say in the first column?

And you DON'T want to move, delete or zip those :}

"ls -ls" OUTPUT:

Hmmm ... that doesn't look quite like the output I'd expect.
What OS, and which version of ls are you using?

Compare to this:

Code:

ls -l /var/lib/ldap/*_db.*
-rw------- 1 openldap openldap    8192 2008-05-13 13:43 /var/lib/ldap/__db.001
-rw------- 1 openldap openldap 2629632 2008-05-13 13:43 /var/lib/ldap/__db.002
-rw------- 1 openldap openldap   98304 2008-05-13 13:43 /var/lib/ldap/__db.003
-rw------- 1 openldap openldap  565248 2008-05-13 13:43 /var/lib/ldap/__db.004
-rw------- 1 openldap openldap   24576 2008-05-13 13:43 /var/lib/ldap/__db.005

ls -ls /var/lib/ldap/*_db.*
  8 -rw------- 1 openldap openldap    8192 2008-05-13 13:43 /var/lib/ldap/__db.001
 55 -rw------- 1 openldap openldap 2629632 2008-05-13 13:43 /var/lib/ldap/__db.002
 16 -rw------- 1 openldap openldap   98304 2008-05-13 13:43 /var/lib/ldap/__db.003
381 -rw------- 1 openldap openldap  565248 2008-05-13 13:43 /var/lib/ldap/__db.004
 12 -rw------- 1 openldap openldap   24576 2008-05-13 13:43 /var/lib/ldap/__db.005

which, btw, is proof of the fact that they are indeed sparse files.
2629632 in fact only occupies 55 blocks (of 1024 bytes each) rather
than 2568 you'd expect.

Cheers,
