[Freeipa-users] Adding indexes for the automounter - odd results

[Sigbjorn Lie]

Hi,

I added indexes for automountKey, and automountmapname  yesterday in my 
test environment to see if that would speed the automounters up a bit, 
and now the automounters does not always work. They manage to look up 
the map, but not the keys in the map.

Restarting the automounter sometimes work for some maps, but then the 
other maps stop working.

Below is an example from the messages file when doing doing "ls /prog."

All folders return like this:

ls: cannot access /prog/nagios: No such file or directory



The 389-ds access log looks like this:

Running the query manually return:

~$ ldapsearch -YGSSAPI -b

'(&(objectClass=automount)(|(automountKey=utils)(automountKey=/)(automountKey=\2a)))'

Running this search without any filter returns:
$ ldapsearch -YGSSAPI -b 
automountmapname=auto_prog,cn=svg1,cn=automount,dc=ix,dc=test,dc=com

<lot of stuff cut away>

# utils -vers\3D3\2Csec\3Dsys filer01:/volumes/p00/prog/utils, auto_prog,
   svg1, automount, ix.test.com
dn: description=utils -vers\3D3\2Csec\3Dsys filer01:/volumes/p00/prog/util
  s,automountmapname=auto_prog,cn=svg1,cn=automount,dc=ix,dc=test,dc=com

automountInformation: -vers=3,sec=sys filer01:/volumes/p00/prog/utils
automountKey: utils
objectClass: automount
objectClass: top

<lot of stuff cut away>

The two indexes I created are these:

# automountkey, index, userRoot, ldbm database, plugins, config
dn: cn=automountkey,cn=index,cn=userRoot,cn=ldbm 
database,cn=plugins,cn=config
cn: automountkey
objectClass: top
objectClass: nsIndex
nsSystemIndex: false
nsIndexType: eq

# automountmapname, index, userRoot, ldbm database, plugins, config
dn: cn=automountmapname,cn=index,cn=userRoot,cn=ldbm 
database,cn=plugins,cn=co
  nfig
cn: automountmapname
objectClass: top
objectClass: nsIndex
nsSystemIndex: false
nsIndexType: eq

And then I ran at these commands:
# /var/lib/dirsrv/scripts-IX-TEST-COM/db2index.pl -D "cn=Directory 
Manager" -w - -n userroot -t automountmapname:eq -v
# /var/lib/dirsrv/scripts-IX-TEST-COM/db2index.pl -D "cn=Directory 
Manager" -w - -n userroot -t automountkey:eq -v

What is going on?
