we want to define the RAID configuration on our masters machines we have 3 masters machines ( while ambari-server installed on master02 machine )
each master machine have 3 partitions one partition for hadoop one partition for zookeeper one partition for hdfs as the following:
/dev/sdb 393G 252M 392G 1% /hadoop /dev/sdc 393G 298M 392G 1% /BD/hadoop/zookeeper /dev/sdd 908G 257M 9008G 1% /BD/hadoop/hdfs
for now we configured the RAID as the following:
raid 0 for /dev/sdb and /dev/sdc
raid 1+0 (raid10) for /dev/sdd
dose the raid configuration that we configured for the partitions on the masters machine is OK ,
or maybe need to configured raid10 also for the other partitions?
