Thanks to all of you for your answers.
I will try the archive tool as recommended by Aravinda.
Just for your information I suppose you are aware that having tons of files such as the CHANGELOGS in one single directory is really sub-optimal. Maybe better would be to have a 2 level hierarchy and store the files using an algorithm to distribute the files among that 2 level hierarchy of sub-directories, especially if there is no archiving of these files by default. Just my two cents ;-)

These 2 cents helps when summed up later :-)

Created a github issues so that we don't miss it : https://github.com/gluster/glusterfs/issues/154

Hi,

I am using geo-replication since now over a year on my 3.7.20 GlusterFS volumes and noticed that the CHANGELOG.<TIMESTAMP> in the .glusterfs/changelogs directory of a brick never get deleted. I have for example over 120k files in one of these directories and it is growing constantly.

So my question, does GlusterFS have any mechanism to automatically delete old and processed CHANGELOG files? If not is it safe to delete them manually?

I will try to answer the question, I'm not an expert in geo-replication, So I could be wrong here. I think GlusterFS won't delete the changelogs automatically, reason being geo-replication is not the author of changelogs, it is just a consumer any other application could use changelogs.

+1 for the reasoning.

You can safely delete *all processed* changelogs from actual changelogs directory and geo-replication directory. You can look into the stime set as the extended attribute on the root to see the time which geo-replication last synced.

If georep is the only consumer, you can use [Aravinda's tool](https://github.com/aravindavk/archive_gluster_changelogs)to move the files to another dir, and delete them.

Regards,
Amar
