Thank you very much Erekle for your links, they are all relevant to me and very interesting as as you mention I will be mostly serving a lot of rather smaller files from my containers.
I will first consider upgrading my gluserfs from 3.8 to 3.10 to take advantage of the small file performance improvements which is afaik newly available in 3.10.
Best regards,
M.

glusterFS is working fine for large files (in most of the cases it's used for VM image store), with docker you'll generate bunch of small size files and if you want to have a good performance may be look in [1] and [2].
Also two node replica is a bit dangerous in case of high load with small files there is a good risk of split brain situation, therefore think about arbiter functionality of gluster [3], I think if you'll apply recommendations from [1] and [2] and deploy arbiter volume.
Cheers

For example here is how I would create my container requiring persistent storage:docker service create --name testcontainer --mount type=bind,source=/mnt/gustervol/testcontainer, target=/mnt alpine What do you think about that? Is this a good way? or is the even a better way?If you are using kubernetes, then please have a look atOtherwise, what you are suggesting works.Raghavendra TalurRegards,M._______________________________________________ Gluster-users mailing list_______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://lists.gluster.org/mailman/listinfo/gluster-users
