[Bug 1435706] Re: DevLossTO, FastIoFailTO settings do not match multipath.conf expected values

2016-03-08 Thread Tore Anderson
Ok, so I found the bug. The problematic code is in
sysfs_attr_set_value() in libmultipath/sysfs.c:

devpath = udev_device_get_syspath(dev);
condlog(4, "open '%s'/'%s'", devpath, attr_name);
if (stat(devpath, ) != 0) {
condlog(4, "stat '%s' failed: %s", devpath, strerror(errno));
return 0;
}

/* skip directories */
if (S_ISDIR(statbuf.st_mode))
return 0;

The problem here is that stat() gets called on the containing directory
in devpath (as opposed to devpath+attr_name). Then the code proceeds to
check if that is a directory (which obviously it is going to be) and
before returning without having done anything. The rest of the function
also seems to assume that "devpath" contains the full path to the sysfs
attribute as opposed to the containing directory.

How the verification in comment #22 could have found this code to be
working is beyond me, as the only place where the attr_name variable is
actively being used for anything in the function is in the condlog()
call.

It appears this got fixed upstream by
http://git.opensvc.com/gitweb.cgi?p=multipath-
tools/.git;a=commit;h=050b24b33d3c60e29f7820d2fb75e84a9edde528 . This
patch applies fine to the multipath-tools 0.4.9-3ubuntu7.9 sources from
trusty (with --fuzz=3), and I can confirm that it does fix the problem
for me - the sysfs timeout attributes gets set correctly when the maps
is being created (both when using multipathd and the multipath tool).

[Bug 1435706] Re: DevLossTO, FastIoFailTO settings do not match multipath.conf expected values

2016-03-07 Thread Tore Anderson
Okay, sorry about the irrelevant verification on Vivid then. But I'd
like to point out that Trusty behaves exactly the same, i.e., the bug is
*not* fixed. Using the exact same multipath.conf as I mentioned in
comment #31 with multipath-tools on 0.4.9-3ubuntu7.9, I get the exact
same behaviour. That is, it is apparent that multipathd does read the
settings from the config file (as they're visible in output from
"multipathd -k'show config'"), but they're not being applied/written to
sysfs.

If I run use the command line utility in verbose mode to create the map,
it does claim that it opens the sysfs files in question, but strace
shows no sign of that actually happening:

[Bug 1435706] Re: DevLossTO, FastIoFailTO settings do not match multipath.conf expected values

2016-03-07 Thread Tore Anderson
I tested it on Vivid, and it does not work. The dev_loss_tmo and
fast_io_fail_tmo sysfs settings do *not* get set. More information on my
test environment below:

root@ucstest:~# cat /etc/multipath.conf

I know for a fact that the device{} section is being applied, because if
I remove the path_grouping_policy keyword and restart multipathd, the
topology changes to one path per group:

root@ucstest:~# sed -i 's/path_grouping/#path_grouping/' /etc/multipath.conf
root@ucstest:~# systemctl restart multipath-tools.service
root@ucstest:~# multipath -ll

After reverting that change and restarting again, I can confirm that my
config file timeout settings are being read by multipathd:

root@ucstest:~# multipathd -k'show config' | grep -B5 -A1 dev_loss_tmo
defaults {

}
--
device {
vendor "HP.*"
product "P2000G3.*"
path_grouping_policy multibus
fast_io_fail_tmo 16
dev_loss_tmo 2048
}

However, they are *not* being applied to sysfs:

[Bug 1548306] [NEW] Attempts to load non-existent module dm-emc

2016-02-22 Thread Tore Anderson
Public bug reported:

The scripts in the multipath-tools-boot referer to a non-existent module
"dm-emc":

/usr/share/initramfs-tools/hooks/multipath:

for x in dm-multipath dm-round-robin dm-emc; do
manual_add_modules ${x}
done

/usr/share/initramfs-tools/scripts/local-top/multipath:

MP_MODULES="dm-multipath dm-emc"
[...]
for module in ${MP_MODULES}; do
  if modprobe --syslog "$module"; then
verbose && log_success_msg "loaded module ${module}."
  else
log_failure_msg "failed to load module ${module}."
  fi
done

The latter code block causes a harmless error message to appear on each
boot.

I believe the references to "dm-emc" can be simply removed.

[Bug 1548303] [NEW] Stale references to /lib/udev/rules.d/95-multipath.rules linger

2016-02-22 Thread Tore Anderson
Public bug reported:

/lib/udev/rules.d/95-multipath.rules was removed in multipath-tools
0.4.9-3ubuntu7.5.

While researching an unrelated issue, I noticed that /usr/share
/initramfs-tools/hooks/multipath still refer to this file:

add_udev_rules()
{
  for rules in 95-multipath.rules; do
if [ -e /lib/udev/rules.d/$rules ]; then
  cp -p /lib/udev/rules.d/$rules $DESTDIR/lib/udev/rules.d/
fi
  done
}

This is dead code that it would probably be best to remove.

[Bug 1547206] Re: Boot stalls on mountall "disk drive not ready" question in multipath-tools >= 0.4.9-3ubuntu7.5

2016-02-18 Thread Tore Anderson
After reviewing the changes between -3ubuntu7.4 and -3ubuntu7.5, I have
found that the problem is caused by the removal of the file
/lib/udev/rules.d/95-multipath.rules. In -3ubuntu7.4, it contained the
following:

#
# udev rules for multipathing.
# The persistent symlinks are created with the kpartx rules
#

# socket for uevents
RUN+="socket:/org/kernel/dm/multipath_event"

# Coalesce multipath devices before multipathd is running (initramfs, early
# boot)
ACTION=="add|change", SUBSYSTEM=="block", RUN+="/sbin/multipath -v0 /dev/$name"

If this file is manually reinstated (either to /lib/udev/rules.d or
/etc/udev/rules.d), boot is again successful (even with the latest
-3ubuntu7.9 multipath-tools package).

I see from the changelog that the removal was intentional:

  * debian/rules: don't ship 95-multipath.rules udev rules anymore; they are
not necessary with multipath-tools listening for udev events directly.
  * debian/multipath.udev: removed.

However, in order for this to actually work with multipath-backed "auto"
filesystems in /etc/fstab, it seems necessary to ensure that multipathd
is started before mountall runs. I am not entirely certain how to
accomplish this, though, as mountall is started from Upstart while
multipath-tools is stuck using a legacy SysV-init, and I do not know if
it is possible to enforce service ordering between the two init systems.
For what it's worth, renaming /etc/rcS.d/S21-multipath-tools-boot as
etc/rcS.d/S00-multipath-tools-boot does not work around the issue.

[Bug 1547206] [NEW] Boot stalls on mountall "disk drive not ready" question in multipath-tools >= 0.4.9-3ubuntu7.5

2016-02-18 Thread Tore Anderson
Public bug reported:

System information: Cisco UCS B200M2 blade, fnic.ko HBA. The system
boots from local storage, but mounts the following file system on an EMC
VNX during bootup:

opt_vnx (3600601603a71320022967e0a1f38e411) dm-0 DGC,VRAID
size=50G features='1 queue_if_no_path' hwhandler='1 emc' wp=rw

`-+- policy='round-robin 0' prio=0 status=enabled
  |- 0:0:1:0 sdb 8:16 active ready running
  `- 1:0:0:0 sdc 8:32 active ready running

/etc/fstab contains:

/dev/mapper/opt_vnx /opt/vnx ext4 noatime 0 2

After upgrading the "multipath-tools" package to version
0.4.9-3ubuntu7.5 or higher, the system can no longer boot without manual
intervention. Instead, the following question is asked (by mountall(8))
on the console:

The disk drive for /opt/vnx is not ready yet or not present.
keys:Continue to wait, or Press S to skip mounting or M for manual recovery

Waiting does nothing useful. Pressing "S" allows the boot to run to
completion, and the "opt_vnx" *is* present when logging in to a
completely booted system. However, it seems that this is discovered
*after* the mountall(8) question appears and is skipped, as this log
line appears later on in the boot process:

 * Discovering and coalescing multipaths...
[ OK ]

Downgrading multipath-tools to version 0.4.9-3ubuntu7.4 does resolve the
problem, and allows the system to boot normally without manual
intervention. Note that the dependent "kpartx" package does *not* need
to be downgraded also, if this is left on version 0.4.9-3ubuntu7.9 it
will still boot fine.

We experience this problem on serveral other systems apart from the one
described in this bug report.

[Bug 1435706] Re: DevLossTO, FastIoFailTO settings do not match multipath.conf expected values

2015-08-29 Thread Tore Anderson
Ok, so I did some more testing. It appears that the problem isn't
specific to the dev_loss_tmo and fast_io_fail_tmo setting. This is
evidenced by the terminal log below. In multipath.conf (which we know
for certain is being read, as the created multipath map gets the correct
alias), I instruct it to use the ALUA hardware handler for all devices.
However, for some reason, this is ignored, and the EMC hardware handler
is used instead:

=
root@ucstest-osl2:~# cat /etc/multipath.conf 
devices {
device {
vendor .*
product .*
hardware_handler 1 alua
}
}

multipaths {
multipath {
wwid 3600601603a71320022967e0a1f38e411
alias bootvolume
}
}
root@ucstest-osl2:~# multipath -v 2
create: bootvolume (3600601603a71320022967e0a1f38e411) undef DGC,VRAID
size=50G features='1 queue_if_no_path' hwhandler='1 emc' wp=undef
|-+- policy='round-robin 0' prio=1 status=undef
| |- 0:0:0:0 sda 8:0  undef ready running
| `- 1:0:1:0 sdd 8:48 undef ready running
`-+- policy='round-robin 0' prio=0 status=undef
  |- 0:0:1:0 sdb 8:16 undef ready running
  `- 1:0:0:0 sdc 8:32 undef ready running
=

This does *NOT* happen on RHEL-based distros - on those, changing the
hardware_handler in multipath.conf in this way works as expected.

So why does it use the EMC hardware_handler? Well, there's a built-in
default device section that matches the array in question. So this
appears to override my user-specified config from multipath.conf:

=
root@ucstest-osl2:~# multipathd -k'show config' | grep -B10 -A4 '1 emc'
device {
vendor DGC
product .*
product_blacklist LUNZ
path_grouping_policy group_by_prio
getuid_callout /lib/udev/scsi_id --whitelisted 
--device=/dev/%n
path_selector round-robin 0
path_checker emc_clariion
checker emc_clariion
features 1 queue_if_no_path
hardware_handler 1 emc
prio emc
failback immediate
no_path_retry 60
}
=

If I copy the entire default device config into /etc/multipath.conf and
only change the hardware_handler setting, then it starts working:

=
root@ucstest-osl2:~# cat /etc/multipath.conf 
devices {
device {
vendor DGC
product .*
product_blacklist LUNZ
path_grouping_policy group_by_prio
getuid_callout /lib/udev/scsi_id --whitelisted 
--device=/dev/%n
path_selector round-robin 0
path_checker emc_clariion
checker emc_clariion
features 1 queue_if_no_path
hardware_handler 1 alua
prio emc
failback immediate
no_path_retry 60
}
}

multipaths {
multipath {
wwid 3600601603a71320022967e0a1f38e411
alias bootvolume
}
}
root@ucstest-osl2:~# multipath -v 2
create: bootvolume (3600601603a71320022967e0a1f38e411) undef DGC,VRAID
size=50G features='1 queue_if_no_path' hwhandler='1 alua' wp=undef
|-+- policy='round-robin 0' prio=1 status=undef
| |- 0:0:0:0 sda 8:0  undef ready running
| `- 1:0:1:0 sdd 8:48 undef ready running
`-+- policy='round-robin 0' prio=0 status=undef
  |- 0:0:1:0 sdb 8:16 undef ready running
  `- 1:0:0:0 sdc 8:32 undef ready running
=

It would appear that for some reason, in order to override default
device settings in Ubuntu there must be an *exact* string match between
the user-supplied «vendor» and «product» settings. If I change e.g.
«product» in multipath.conf to .*.*, then it starts using the built-in
defaults again, ignoring multipath.conf. I consider this behaviour very
dangerous - consider that if the admin has a working config (due to
exact matching vendor/product settings), and then the package gets
updated and extends the built-in defaults to incorporate some new model
matching the same profile/settings). At this point the admin's working
config will stop being used, possibly causing disruptive problems. I
therefore strongly suggest you figure out why it behaves differently in
Ubuntu and RHEL, and adopt the RHEL behaviour which really is the only
sensible one.

In any case, now that I know how to ensure my multipath.conf settings
are being used, I re-tried adding dev_loss_tmo and fast_io_fail_tmo, but
it still doesn't work:

=
root@ucstest-osl2:~# cat /etc/multipath.conf 
devices {
device {
vendor DGC
product .*
product_blacklist LUNZ
path_grouping_policy group_by_prio
getuid_callout /lib/udev/scsi_id --whitelisted 
--device=/dev/%n
path_selector round-robin 0
path_checker emc_clariion

I verified that this bug is *NOT* fixed by trying the exact identical
configuration (which is as minimal as possible) both with Ubuntu Trusty
and with Scientific Linux 6 (RHEL6 clone). The test machine is a Cisco
B200M2 blade server, using the Cisco VIC FCoE HBA (fnic.ko driver). The
storage array is an EMC VNX5300, which is reached via FCoE (inside the
Cisco UCS infrastructure) and then traditional FC fabric.

The following console output is taken with Trusty installed. Note that
it was fully upgraded. After creating /etc/multipath.conf with the
indicated contents, update-initramfs was run and the system rebooted,
just to make sure the settings had taken effect. As you can see from the
output, the dev_loss_tmo and fast_io_fail_tmo settings are *NOT*
applied:

2015-07-31 Thread Tore Anderson
To me fix doesn't actually appear to work. After upgrading to multipath-
tools 0.4.9-3ubuntu7.4on an amd64 trusty and rebooting, the
fast_io_fail_tmo and dev_loss_tmo values do not get written to sysfs:

$ grep . /sys/class/fc_remote_ports/*/*_tmo
/sys/class/fc_remote_ports/rport-2:0-0/dev_loss_tmo:30
/sys/class/fc_remote_ports/rport-2:0-0/fast_io_fail_tmo:off

/sys/class/fc_remote_ports/rport-3:0-1/fast_io_fail_tmo:off

The device stanza from multipath.conf contains the following:

FWIW, I can manually set the sysfs settings to the desired values:

[Bug 1472129] [NEW] irqbalance triggers Upstart bug when started with --policyscript

2015-07-07 Thread Tore Anderson
Public bug reported:

If irqbalance is started with the --policyscript option, Upstart is
unable to manage it properly (bug #406397 is being triggered), and
stopping/restarting it fails. Noticed this when the
1.0.6-2ubuntu0.14.04.2 update hit Trusty yesterday. See below:

$ /sbin/stop irqbalance
irqbalance stop/waiting
$ echo 'OPTIONS=--policyscript=/bin/true'  /etc/default/irqbalance
$ /sbin/start irqbalance
irqbalance start/running, process 23862
$ /sbin/status irqbalance
irqbalance start/running, process 23862
$ pgrep -a irqbalance
23859 /usr/sbin/irqbalance --policyscript=/bin/true
23871 /usr/sbin/irqbalance --policyscript=/bin/true
[note how the PIDs don't match what Upstart believes them to be]
$ /sbin/stop irqbalance
[hangs]
^C
$ /sbin/status irqbalance
irqbalance stop/killed, process 23862
$ pgrep -a irqbalance
23859 /usr/sbin/irqbalance --policyscript=/bin/true
23871 /usr/sbin/irqbalance --policyscript=/bin/true
$ /sbin/start irqbalance
[hangs]

I successfully recovered from this situation by running the hack at
https://raw.githubusercontent.com/ion1/workaround-upstart-snafu/master
/workaround-upstart-snafu on all the servers that had attempted to
upgraded the irqbalance package.

One easy way to fix this issue is to remove expect fork and instead
start irqbalance with the --foreground option. Patch attached.

On a related note, I see that the irqbalance package ships both a SysV
init script in /etc/init.d/irqbalance as well as an Upstart job
definition. That's rather confusing to a sysadmin, and could possibly
lead to collisions? As I understand it, the SysV init script for an
Upstart-managed service is supposed be replaced by a symlink to
/lib/init/upstart-job. Maybe you'll want to look into that as well.

This affects me, too. After boot, the necessary ipmi_{si,devintf}
modules aren't loaded, so ipmitool and related monitoring doesn't work.

However this bug cannot possibly be in the ejabberd package, so I'm
reassigning it to openipmi.

[Bug 715141] Re: Default NTP servers do not have AAAA records

2014-07-07 Thread Tore Anderson
We notice this here as well, as we're increasingly turning up new
services and VMs without IPv4. It fails with a rather cryptic error
message:

Jul  8 07:10:03 rpki-validator ntpdate[689]: Can't find host ntp.ubuntu.com: 
Name or service not known (-2)
Jul  8 07:10:03 rpki-validator ntpdate[689]: no servers can be used, exiting

Jul  8 07:10:03 rpki-validator ntpdate[726]: no servers can be used, exiting

If the Ubuntu sysadmin team does not manage to dual-stack their public
NTP service in three years, perhaps it is time for the ntpdate package
to switch to 2.pool.ntp.org?

Not this exact problem but one with similar symptoms. From kernel 3.5
onwards there was a problem with guests not receiving RTC ticks which
was reported here - http://lists.gnu.org/archive/html/qemu-
devel/2013-02/msg03827.html

The 3.2 kernel from 12.04.1 never had any issues but the 3.5 kernel from
12.04.2 onwards hit the RTC bug whoch was fixed in later releases of
QEMU.

2014-05-25 Thread Matthew Anderson
Based on the fact that flush_tlb_page() appears to be taking up most of
the CPU time when QEMU is 'frozen' I started playing with memory
settings. Disabling automatic NUMA balancing appears to have solved the
problem. echo 0  /proc/sys/kernel/numa_balancing

The guest has been running 4+ hours now without an issue. I currently
have KSM and transparent huge pages enabled.

[Bug 1099875] [NEW] multipathd ignores dev_loss_tmo and fast_io_fail_tmo settings

2013-01-15 Thread Tore Anderson
Public bug reported:

My device section of /etc/multipath.conf contains the following (I'll
attach the complete file in a bit):

fast_io_fail_tmo 3
dev_loss_tmo 2147483647

This is also visible in the output from multipathd -kshow config, so
it's being correctly parsed. However, the settings appears to be
completely ignored by multipathd, as the corresponding sysfs settings
doesn't get updated:

$ grep . /sys/class/fc_remote_ports/rport-*/*tmo
/sys/class/fc_remote_ports/rport-2:0-0/dev_loss_tmo:30
/sys/class/fc_remote_ports/rport-2:0-0/fast_io_fail_tmo:off
/sys/class/fc_remote_ports/rport-3:0-0/dev_loss_tmo:30
/sys/class/fc_remote_ports/rport-3:0-0/fast_io_fail_tmo:off

These are the kernel's defaults. I can easily set them manually:

$ echo 3 | tee /sys/class/fc_remote_ports/rport-*/fast_io_fail_tmo
3
$ echo 2147483647 | tee /sys/class/fc_remote_ports/rport-*/dev_loss_tmo
2147483647
$ grep . /sys/class/fc_remote_ports/rport-*/*tmo
/sys/class/fc_remote_ports/rport-2:0-0/dev_loss_tmo:2147483647
/sys/class/fc_remote_ports/rport-2:0-0/fast_io_fail_tmo:3
/sys/class/fc_remote_ports/rport-3:0-0/dev_loss_tmo:2147483647
/sys/class/fc_remote_ports/rport-3:0-0/fast_io_fail_tmo:3

However, this won't survive a reboot, and since SAN paths may appear at
any time, adding the above to /etc/rc.local is also not a good way to
fix it.

I've also attempted to move the settings to the defaults section and the
individual path sections. No change in behaviour.

This bug prevents dm-multipath from quickly moving I/O away from a
recently failed SAN path, instead stalling all I/O for 30 seconds. This
defeats the purpose of using multipathing in the first place, which is
to have highly available I/O access so that production can continue
uninterrupted even if parts of the SAN fabric fails.

The setting works on RHEL6, btw.

[Bug 1027418] [NEW] Functions from upstream missing in package

2012-07-21 Thread Eric Anderson
Public bug reported:

The libkrb5 package in 12.04 looks like it's missing some functions.
That sounds weird, so let me explain:

I have the following packages installed:
$ dpkg-query -l 'libkrb*'
[snip]
ii  libkrb5-26-heimdal1.6~git20120311.dfsg.1-2  Heimdal Kerberos - 
libraries
ii  libkrb5-3 1.10+dfsg~beta1-2 MIT Kerberos runtime 
libraries
ii  libkrb5-dev   1.10+dfsg~beta1-2 Headers and development 
libraries for MIT Kerberos
ii  libkrb5support0   1.10+dfsg~beta1-2 MIT Kerberos runtime 
libraries - Support library

The functions  'krb5_cccol_lock' and  'krb5_cccol_unlock' are declared
in  /usr/include/krb5/krb5.h, from libkrb5-dev.   When I try to use them
in a program that links against libkrb5, I get an undefined symbol
error at run time.  I've looked at every .so file defined in any of
those packages (using nm and nm -D), and those symbols aren't mentioned
in any of those files!

When I build krb5-1.10.2 from the MIT source, those symbols are defined

[Bug 875440] Re: Cannot authenticate with saslauthd and mysql

2012-05-01 Thread E.T. Anderson
I can confirm this effects Precise 12.04.

I was able to somewhat work around this by changing the SASL auth
mechanism from 'pam' to 'rimap' though I have yet to get authentication
working in Roundcube. At lest testsaslauthd succeeds with the rimap
mechanism.

[Bug 405195] [NEW] When stopping a specific daemon, _all_ routes are flushed

2009-07-27 Thread Tore Anderson
Public bug reported:

Binary package hint: quagga

This misbehaviour just bit me:

r...@fwtest1:~# /etc/init.d/quagga stop ospf6d
Stopping Quagga daemons (prio:0): ospf6d.
Removing all routes made by zebra.

So I'm stopping ospf6d only, but _all_ routes, including the ones
installed by still-running processes such as bgpd, ripd, and so on, are
removed from the kernel's routing table.  That can't be right.

I suggest applying the following patch so that the flushing will only
happen if all of the Quagga daemons are stopped:

[Bug 48857] Re: OSPFd automatically adds an invalid configuration line

2008-09-23 Thread Tore Anderson
Haven't tried (running a Feisty backport at the moment), but I expect
not.  It was supposedly fixed upstream in version 0.99.3, and Intrepid
currently ships with 0.99.9.

It's likely still present in Dapper, though.

You're right about that, at least it still doesn't work after the
upgrade to openvpn 2.1~rc9-3ubuntu1.  Still fails with the script-

[Bug 227178] Re: [SRU] Slave slapd crashes when doing syncrepl

2008-06-20 Thread Anderson
Sorry, I didn't saw your packages before, because of version numbering.
I had installed packages from Chuck's PPA, with version
2.4.9-1ubuntu1~ppa1 and packages from hardy-proposed has version
2.4.9-0ubuntu0.8.04.

In order to allow automatic installation of hardy-proposed packages with
a standard dist-upgrade, can version numbering be changed?

[Bug 234196] [NEW] dnPrettyNormal: Assertion `pretty != ((void *)0)' failed.

2008-05-22 Thread Anderson
Public bug reported:

In slapo-unique(5) manpage, I read I was using deprecated directives in
my LDAP configuration files:

overlay unique
 unique_attributes gidNumber uid uidNumber sambaSID
 unique_base ou=people,dc=cefetrs,dc=tche,dc=br

So, I changed to this:

overlay unique
 unique_uri 
 ldap:///ou=people,dc=cefetrs,dc=tche,dc=br?uid,uidnumber,sambasid,mail?sub

And now, I get a failed assertion:
$ ./create-master-base.sh
slapadd: /build/buildd/openldap2.3-2.4.7/servers/slapd/dn.c:724: 
dnPrettyNormal: Assertion `pretty != ((void *)0)' failed.
./create-master-base.sh: line 2: 28237 Cancelado   slapadd -f 
slapd.conf -l data.ldif -b 'dc=cefetrs,dc=tche,dc=br'

This line shows the assertion fail in slapadd command, but it occurs
in slapd, if I use my main base.

Steps to reproduce (almost same steps in #227178):

# Download my attachment and extract the BZIP archive on an existing folder 
'/home/amg1127'.
# cd to '/home/amg1127/ldap
# Create the database from the included LDIF by running 
'./create-master-base.sh'
# Got a SIGABRT
slapadd: /build/buildd/openldap2.3-2.4.7/servers/slapd/dn.c:724: 
dnPrettyNormal: Assertion `pretty != ((void *)0)' failed.

# Remove /home/amg1127/ldap folder and entire content within
# Extract the BZIP archive on that folder again
# Edit the file /home/amg1127/ldap/maindb-commonparams.conf, comment line 45 
and uncomment lines 42 and 43.
# Create the database from the included LDIF by running 
'./create-master-base.sh'
# Edit the file /home/amg1127/ldap/maindb-commonparams.conf, uncomment line 45
