Althgh I would say to fix the Fail message you can do the follwoing

 

in the install type in the end --failure-threshold NONE

As below

Stops the installation when the specified failure threshold is encountered. Options can be one of: HINT - Stop the install if a HINT or greater issue is encountered during the installation tests. HINT configurations are settings you should make, but the database runs with no significant negative consequences if you omit the setting. WARN (default) - Stop the installation if a WARN or greater issue is encountered. WARN issues may affect the performance of the database. However, for basic testing purposes or Community Edition users, WARN issues can be ignored if extreme performance is not required. FAIL - Stop the installation if a FAIL or greater issue is encountered. FAIL issues can have severely negative performance consequences and possible later processing issues if not addressed. However, Vertica can start even if FAIL issues are ignored. HALT - Stop the installation if a HALT or greater issue is encountered. The database may not be able to be started if you choose his option. Not supported in production environments. NONE - Do not stop the installation. The database may not start. Not supported in production environments.

 It will not cause a problem thereafter ? because i wanna solve this problem , but i have LVM filesystem

In my installations I have not seen any issues. But it is up to you

MdaHpe

You had the same alerts before completing the installation?

ckotsidimos

Yes I had them in some cases

james_peng

are you using lvm instead of ext4?

I think vertiva did not support lvm type file system

MdaHpe

yes  i know that vertica dont support it but how to resolve it
