Where Is The Installer Located On ZCA After Download

Here is an example of the ZCA 8.0.3 Release: 

/opt/vmware-zca-installer/packages/zcs-NETWORK-8.0.3_GA_5664.UBUNTU10_64.20130305090216.tgz

Mailboxd Not Running After ZCS 803 Upgrade

Check /opt/zimbra/log/zmmailboxd.out for the following: 

2013-03-22 09:44:50.496:INFO:oejpw.PlusConfiguration:No Transaction manager found - if your webapp requires one

This should be getting fixed ASAP, so hopefully no one else hits it.

Hostname Keeps Being Set To Localhost

This is a 'bug' of sorts in the vmware scripts. It requires the hostname to have a valid PTR record, if it doesn't upon a DNS query it will fall back to localhost.

Steps That Should Work, But Don't Because Of PTR Not Being Set

Edit /etc/hosts as root: 

127.0.0.1 localhost.localdomain localhost
XXX.XXX.X.X  HOSTNAME.DOMAIN.COM HOSTNAME

Edit /etc/hostname as root to have your FQDN: 

 HOSTNAME.DOMAIN.COM

Push out changes, as root: 

 /etc/init.d/hostname start

The vmware tool sets the hostname also via this: 

# /opt/vmware/share/vami/vami_config_net 
Main Menu 

0) Show Current Configuration (scroll with Shift-PgUp/PgDown) 
1) Exit this program 
2) Default Gateway 
3) Hostname 
4) DNS 
5) Proxy Server 
6) IP Address Allocation for eth0 
Enter a menu number [0]:

Time Is Not Set Right

Postfix might not start because of this.

The following RFE is to have this configured so upon start time is pulling from ntp.

To manually update time to pull from a ntp server: 

ntpdate ntp.ubuntu.com pool.ntp.org

Increasing Disk - Partition Space

General References On LVM And Commands For It

You should be comfortable with LVM and working with it. Zimbra Support does not support this directly, this is a normal Linux administrative tasks and trouble shooting and training issues should be directed to your Linux OS vendor.

References:

Increase - Adding Disk - : Add Storage First in vSphere

This wiki applies to ZCA 8.0.0 and newer.

Adding additional VMDKs for storage is done via the normal vSphere client process.

  • For a single server installation, select the Zimbra Appliance; for a multi server installation, select the mailstore server to add storage.
  • From Edit, click Add.
  • Select Hard Disk and click Next.
  • Select Create a new virtual disk. If you are using Raw Device Mapping (RDM), select Raw Device Mappings.
  • Select the provision format that is the same as the Zimbra Appliance virtual machine. Recommended is Thick Provision Eager Zero format. If you are deploying on fiber channel storage, this provides the best performance for the appliance.
  • Select Specify a datastore or datastore cluster.
  • Click Browse to select a datastore to create the virtual disk on.
  • Once you have added the appropriately sized VMDKs for your deployment, restart your Zimbra appliance virtual machine. The virtual appliance console indicates the volume group for the virtual appliance that is being increased.
  • Login to the storage virtual appliance and as root enter:
    • vgdisplay data_vg
  • This displays the volume group properties for the Zimbra mailstore server. Verify that the volume group size reflects the size of the added storage plus 12GB.

If you do not see the increase disk space for the data_vg , proceed with the below section.

Manually Adding - Expanding the Disk - Partition In The OS

Note - Ideally the link below should work for you and be the best method to adding/increasing disk space on ZCA

Keyword - zca partition disk full.

All you should have to do is add new disks to be available to the ZCS virtual machine and then reboot the zimbra server. A script should detect it and auto-expand the partition to give you the newly available space. If this does not happen, you'll be able to confirm that the volume group [vg] is still the same size but you will see the new disks with the output of fdisk.

To see what the vg data_vg currently is: 

root@localhost:~# vgdisplay data_vg
--- Volume group ---
VG Name data_vg
System ID
Format lvm2
Metadata Areas 1
Metadata Sequence No 2
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 1
Open LV 1
Max PV 0
Cur PV 1
Act PV 1
VG Size 12.00 GiB
PE Size 4.00 MiB
Total PE 3071
Alloc PE / Size 3071 / 12.00 GiB
Free PE / Size 0 / 0
VG UUID BDfVzQ-zVEP-jiAm-DI1J-2sje-01cc-1rMJ9K

To see what disks are available to you - as root, fdisk -l . Example below : 

root@localhost:~# fdisk -l

Warning - What your about to do is irreversible. You should confirm and double check that you have your data backed up and are knowledgeable about your DR options if things go wrong beyond this point.


To manually add the new disks to the lvm vg to expand the partition that's available to zimbra. Reusing the example from above. As root : 


root@localhost:~# pvcreate /dev/sdc

root@localhost:~# pvcreate /dev/sdd

root@localhost:~# vgextend /dev/data_vg /dev/sdc

root@localhost:~# vgextend /dev/data_vg /dev/sdd

root@localhost:~# lvextend -L +79.99g /dev/data_vg/zimbra

root@localhost:~# resize2fs /dev/data_vg/zimbra

Additional Information

Very useful commands that will show information about your PV's, LV's, and VG's :

  • pvs -v
  • lvs -v
  • vgs -v
