<p>Beberapa hari yang lalu, saya sedang ada pekerjaan migrasi sistem email server Zimbra untuk salah satu klien. Migrasi dari Zimbra versi 8.6 ke Zimbra versi 8.8.15 Network Edition dengan metode rebuild ulang. Dengan metode rebuild ulang, maka pasti ada namanya proses backup restore data mailbox. Nahh ketika sedang melakukan proses restore data pada email server baru, saya menemukan sedikit keanehan.</p>
<p>Keanehan tersebut ialah data /opt/zimbra pada server baru besarnya hampir 3 kali lipat daripada data /opt/zimbra di server lama. Jika dilihat menggunakan command du -h, yang membuat /opt/zimbra menjadi 3 kali lipat lebih besar ternyata ada folder /opt/zimbra/redolog dengan size yang cukup besar.</p>
<pre>[root@mbox01 ]# du -h --max-depth=1 /opt/zimbra/ 
<span style="color: #ff0000;">78G	/opt/zimbra/redolog</span> 
127M	/opt/zimbra/log 
619M	/opt/zimbra/jetty_base 
561M	/opt/zimbra/common 
2.2G	/opt/zimbra/index 
<span style="color: #3366ff;">43G	/opt/zimbra/store</span> 
1.9M	/opt/zimbra/zimlets-network 
1012M	/opt/zimbra/logger 
49G	/opt/zimbra/bs-store 
1.6G	/opt/zimbra/db 
175G	/opt/zimbra/ 
</pre>
<p>Bahkan ukuran folder /opt/zimbra/redolog lebih besar daripada folder /opt/zimbra/store tempat menyimpan data mailbox user. Jika dilihat lebih dalam ke dalam folder /opt/zimbra/redolog, terdapat folder archive yang isinya banyak file redo.log yang perhari nya bisa 1Gb keatas, seperti contoh screenshot berikut.</p>

<p>File redolog ini digunakan oleh Zimbra untuk point restore data email, dan digunakan pada Zimbra versi lawas. Namun semenjak muncul fitur baru <strong>Zimbra Backup-NG</strong>, redolog ini sudah tidak digunakan lagi, tapi secara service, redolog ini tetap berjalan sehingga memenuhi space harddisk yang ada, jadi kita harus disable manual untuk redolog tersebut.</p>
<p><strong>Baca Juga : <a href="https://rizkypratama.id/blog/2019/01/24/aktivasi-https-mailman-zimbra/" target="_blank" rel="noopener noreferrer">Aktivasi HTTPS pada Akses Mailman Zimbra</a></strong></p>
<p>Berikut ini langkah-langkah untuk disable redolog pada Zimbra</p>
<p>1. Pastikan menggunakan Zimbra Network Edition versi terbaru 8.8. keatas dan sudah ada fitur Zimbra Backup-NG</p>
<p>2. Jalankan command berikut untuk disable redolog</p>
<pre>su - zimbra 
zmprov mcf zimbraRedoLogDeleteOnRollover TRUE 
</pre>
<p>3. Lalu restart service mailbox Zimbra nya untuk apply perubahan tersebut</p>
<pre>zmmailboxdctl restart</pre>
<p>4. Hapus file-file redolog lama yang memenuhi harddisk</p>
<pre>cd /opt/zimbra/redolog/archive/ 
rm -rvf redo-* 
</pre>
<p>Jika proses hapus redolog sudah selesai, semestinya sisa space harddisk saat ini sudah bertambah, dan redolog sudah terdisable, jadi kedepannya tidak akan ada lagi file redo-xxx.log pada folder /opt/zimbra/redolog/archive/ yang memenuhi space harddisk</p>
<p>Mungkin cukup sekian, semoga bermanfaat</p>
