=== Disk Hata Kontrolü===
badblocks programı kullanılarak sabit  disklerde kurulum öncesi bad block olup olmadığının kontrolü yapıldı. İlgiki Betik.

 root@zula201:~/ulakceph# more systest.sh 
 #!/bin/bash
 for disk in `lsblk | grep -i 7.3 | awk  '{print $1}'` 
     do badblocks -b4096 -w  -o ${disk}.badblock.txt /dev/${disk} &
 done

== Driver ve Firmware Güncellemleri==
=== 10G Intel Ethernet Kartı Driver Güncellemesi===
Linux çekirdeği ile gelen driver yerine Intel web sayfasından 10G ethernet kartının güncel driver'larının indirilerek kurulması daha az sorun ve daha yüksek performans almanızı sağlayacaktır.
