we found error info:

the partition '/srv/BigData/redis/Redis_1' size '186.1'(G) does not match the configured size '200'(G) of directories:'/srv/BigData/redis/Redis_1'. [checkEnvironmentOnEachHost.sh(main):664](40410)

the partition '/srv/BigData/redis/Redis_4' size '186.1'(G) does not match the configured size '200'(G) of directories:'/srv/BigData/redis/Redis_4'. [checkEnvironmentOnEachHost.sh(main):664](40410)
the partition '/srv/BigData/redis/Redis_5' size '186.1'(G) does not match the configured size '200'(G) of directories:'/srv/BigData/redis/Redis_5'. [checkEnvironmentOnEachHost.sh(main):664](40410)

Handling Process

we check the LLD design tool excel check the disk plan for '/srv/BigData/redis/Redis_1', found below information

the Minimum disk capacity in design is 1000GB,

And this 1000GB divided to 5 partition, so  each partition must 200GB.

But  the actually disk capacity is less than 1000GB for each partition only can support 186GB, so preinstall report this error.

We change the minimum disk capacity to 900GB in LLD design and upload the new design file to the manage node, then preinstall check successfully.

 

 

Root Cause

The mininum disk capacity is less than design.

Solution

We change the minimum disk capacity to 900GB in LLD design and upload the new design file to the manage node.

Suggestions

when we design the minimum disk capacity check it in system then design it
