What is the correct way to update Navigator Metadata Server Storage Dir

[#1]

Hi,

currently we setup our Navigator Metadata Server Storage Dir into /var/lib/cloudera-scm-navigator

and the problems is the free space of /var partition is very low, now.

could you guys inform me, what is the correct way to move /var/lib/cloudera-scm-navigator/solr into /data1/solr

note: sorry for my english

Thanks

First of all, you have to stop Navigator.

Then it depends on what you decide.

The easiest approach (not requiring changes in configuration) is to move the directory and create a link:

# mv /var/lib/cloudera-scm-navigator/solr  /data1/
# ln -s /data1/solr  /var/lib/cloudera-scm-navigator/solr

Although I would prefer to move the whole navigator directory:

# mv /var/lib/cloudera-scm-navigator/ data1/
# ln -s /data1/cloudera-scm-navigator  /var/lib/cloudera-scm-navigator

 The last approach is again to move the directory without link

# mv /var/lib/cloudera-scm-navigator/ data1/

 and change

Navigator Metadata Server Storage Dir

nav.data.dir

in Cloudera Manager to

/data1/cloudera-scm-navigator

Hope, that helps. As mentioned above, I prefer the second approach, because all directory is in one partition plus, someone new in your team won't have to check CM for the new location.

Hi GeKas,

Thank you for your answer.

First of all, you have to stop Navigator.

do I need to stop all of Cloudera Management Service or just  Navigator Audit Server & Navigator Metadata Server.

Thanks

No you don't have to stop all Management Services.

Only Navigator Metadata Server is enough, but you can stop also Navigator Audit server if you feel more safe.
