Did you stopped DB ?

Support just said to stop Retain using stop tomcat command.  I am guessing mysql needs tob be stopped and then copied?

Sure, DB need to stopped.

Even with mysql stopped the mysql.sock "special file" is there and will not copy.  Is it needed for me to point retain to the new location of data files?

Which directories do you copy?

Usually I use rsync to copy files to the new location. So you can start in an early state. In between you just rsync differential data. On your  final day you stop all involved services, do your final rsync and rename original directories (in case of trouble shooting).

If you do not use default directories then maybe you have used symbolic links to pretend default directories; in this case you have to change these links to the new location. So your question is answered here - yes, Retain has to know where to find and store its data.

Ok, so I successfully moved the data to the new drive (except for the mysql.sock file) and changed all the data locations in the ASConfig file after backing up the file).  Then restarted the server with the retain installation pointing to the new location.  The web console is ow a loading screen with the last line being "EDT 2021: Stage (turnOnIndexing) Type (begin ) Info (Launch Indexing)".

I am guessing it is re-indexing?

So you moved your index files too ... and your index location directory is /var/opt/beginfinite/retain/index (default location)?

I did not move anything that was not in the data location.  That was two directories:  mysql and retain

I did not move server host, just added a bigger expandable drive and copied the /data contents which was the archive data.

as you are doing a partial server move, perhaps the server move document may be of some assistance as it has helped me on a couple moves already

i saw that and used part of it for the retain file locations, but this seems to be the mysql db.  i am assuming it is in the same data folder as the retain archives.  Micro Focus support isnt being much help. Just sending me tids and telling to call Microsoft for mysql issue.?????
