Goal

This note gives some tips on how to troubleshoot a case where:

1. The resynchronization step of an OS disk replacement is taking a very long period of time. 

You would be at this place when configuring an OS disk during the step to resynchronize in the "Repairing the RAID Arrays" section of:

a) How to Configure a Server Disk After Disk Replacement as an Operating System Disk for /u02 and /dev/sdb on Oracle Big Data Appliance V2.2.*/V2.3.1/V2.4.0/V2.5.0/V3.0.0/V3.0.1/V3.1.0/V4.0.0/V4.1.0/V4.2.0/V4.3.0 (Doc ID 1581373.1).
b) How to Configure a Server Disk After Disk Replacement as an Operating System Disk for /u01 and /dev/sda on Oracle Big Data Appliance V2.2.*/V2.3.1/V2.4.0/V2.5.0/V3.0.0/V3.0.1/V3.1.0/V4.0.0/V.4.1.0/V4.2.0/V4.3.0 (Doc ID 1581338.1).

or

2. The partition format of an HDFS disk is taking a very long period of time.

You would be at this place when configuring an HDFS disk during the step to format the partition in the "Partitioning a Disk for HDFS or Oracle NoSQL Database" section of:

How to Configure a Server Disk After Replacement as an HDFS Disk or Oracle NoSQL Database Disk on Oracle Big Data Appliance V2.2.*/V2.3.1/V2.4.0/V2.5.0/V3.0.0/V3.0.1/V3.1.0/V4.0.0/V4.1.0/V4.2.0/V4.3.0 (Doc ID 1581583.1).
