[Gluster-users] Gluster Performance - 12 Gbps SSDs and 10 Gbps NIC
Hi Gilberto,
Have you
checked?https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5/html/administration_guide/chap-configuring_red_hat_storage_for_enhancing_performance??
I think that you will need to test the virt profile as the settings?will prevent
some bad situations - especially VM live migration.You should also consider
sharding which can reduce healing time but also makes your life more difficult
if you need to access the disks of the VMs.
I think that client.event-thread ,?server.event-thread and
performance.io-thread-count?can be tuned in your case. Consider setting ip a VM
using the gluster volume as backing store and run the tests inside the VM to
simulate real workload (best is to run a DB, webserver, etc inside a?VM).
Best Regards,Strahil Nikolov?

Only Replica 2 or Distributed Gluster volumes can be created with two servers.
High chance of split brain with Replica 2 compared to Replica 3 volume.
For NFS Ganesha, no issue exporting the volume even if only one server is
available. Run NFS Ganesha servers in Gluster server nodes and NFS clients from
the network can connect to any NFS Ganesha server.
You can use Haproxy + Keepalived (or any other load balancer) if high
availability required for the NFS Ganesha connections (Ex: If a server node goes
down, then nfs client can connect to other NFS ganesha server node).

Yeah 2355MB/s is much better than the original 115MB/s
So in the end, I guess FUSE isn't the best choice.

Nope, not a caching thing. I've tried multiple different types of fio tests,
all produce the same results. Gbps when hitting the disks locally, slow MB\s
when hitting the Gluster FUSE mount.
I've been reading up on glustr-ganesha, and will give that a try.

Dismiss my first question: you have SAS 12Gbps SSDs? Sorry!
El 12/12/23 a les 19:52, Ramon Selga ha escrit:
May ask you which kind of disks you have in this setup? rotational, ssd
SAS/SATA, nvme?
Is there a RAID controller with writeback caching?
It seems to me your fio test on local brick has a unclear result due to some
caching.
Try something like (you can consider to increase test file size depending of
your caching memory) :
fio --size=16G --name=test --filename=/gluster/data/brick/wow --bs=1M
--nrfiles=1 --direct=1 --sync=0 --randrepeat=0 --rw=write --refill_buffers
--end_fsync=1 --iodepth=200 --ioengine=libaio
Also remember a replica 3 arbiter 1 volume writes synchronously to two data
bricks, halving throughput of your network backend.
Try similar fio on gluster mount but I hardly see more than 300MB/s writing
sequentially on only one fuse mount even with nvme backend. On the other side,
with 4 to 6 clients, you can easily reach 1.5GB/s of aggregate throughput
To start, I think is better to try with default parameters for your replica
volume.
Best regards!
Ramon

Check if you can use MTU9000 and if it?s possible, set it on the Bond Slaves and

Oh no, what's wrong? From 2182MB/s down to only 115MB/s? What am I missing?
I'm not expecting the above ~17 Gbps, but I'm thinking it should at
least be close(r) to ~10 Gbps.
Any suggestions?
