Dear List.
i am very happy with my glusterfs replica 2 so far.
i have two volumes (one 16TB raid5 on each server) devided into 2 8 TB
partitions which are used as volumes
I configured some volume options via
gluster volume set ....
the options so far:
performance.cache-size: 34359738368
performance.io-thread-count: 32
cluster.data-self-heal-algorithm: full
performance.quick-read: on
Now i read in the internet many posts about editing vol files. do i need
to configure my vol files?
i have one volfile under /etc/gluster/glusterd.vol
and for each volume another two (for each server) under
/var/lib/glusterd/<volname>/
But in neither volfile i am able to find a translator section of the
options that i reconfigured.
Do i need to create this sections manually?
Background:
actually we are driving a 5 node proxmox cluster which uses NFS as
storage from a fileserver.
Now we want to replace this setup with a 3 node proxmox cluster, from
which 2 machines act as gluster replica 2
All test showed that the new setup is 200% faster than the old one,
except a linux DB2 vm, which takes double time to write into database
(on insert and delete oprations)
I want to optimize gluster for use of the databases and will now test
the quickread option, do you think this will bring any performance?
Thank you
Alex
