How to move the Transaction Storage of Dynatrace Managed to another directory

[reginaldo_alves]

Hi all,

Managed Transaction storage is currently pointing to directory and due to space problems, I need to move It to another directory mounted in another partition. Does anyone have a procedure to do that?

Tks

Hey Reginaldo,

how about stopping the cluster, then copy data from the directory to a new location. After that mounting a new partition to the old directory?

Anyway, re-mounting should work with keeping in mind the file structure should be
preserved and file access as well.

In case you need assitance, don't hesitate to contact with our support guys!

I was asking if the BIG data files (/opt/dtmanaged/data/server, /opt/dtmanaged/data/Cassandra and /opt/dtmanaged/data/elasticsearch) can be stored at another location e.g. /var/spool/dtmanaged/data* and all other binaries and log files kept in the same location as before (/opt/dtmanaged/*). The installation is already complete and the cluster is up since 1 year.

We wanted to allocate higher storage to /var/spool/dtmanaged and keep the BIG data files there without disturbing the Dynatrace binaries and log files that would continue to be in /opt/dtmanaged/* folders.

Is there any way, this can be done? We tried to change cassandraDatastoreDir in config.properties file and restarted the service but it still kept writing to the old location.

Thanks,

Abhaya

Please do not modify configuration files.

To do it what you want, please follow my comment above. Just stop the cluster, copy files to new location and create a symlink or mount other volume under old path.
