similar to: Slow Read Performance With Samba GlusterFS VFS

Hello? We have used glusterfs3.4 with the lasted samba-glusterfs-vfs lib to test samba performance in windows client. two glusterfs server nodes export share with name of "gvol": hardwares: brick use a raid 5 logic disk with 8 * 2T SATA HDDs 10G network connection one linux client mount the "gvol" with cmd: [root at localhost current]# mount.cifs //192.168.100.133/gvol

Why don?t you set LSI to passtrough mode and set one brick per HDD?

Hi Brandon, Can you please turn OFF client-io-threads as we have seen degradation of performance with io-threads ON on sequential read/writes, random read/writes. Server event threads is 1 and client event threads are 2 by default.

Hi folks, We found that samba performance downgrade a lot with glusterfs backend. volume info as followed, Volume Name: vol1 Type: Distribute Status: Started Number of Bricks: 1 Transport-type: tcp Bricks: Brick1: pana53:/data/ Options Reconfigured: auth.allow: 192.168.* features.quota: on nfs.disable: on Use dd (bs=1MB) or iozone (block=1MB) to test write performance, about 400MB/s. #dd

Hi gluster users, I've spent several months trying to get any kind of high performance out of gluster. The current XFS/samba array is used for video editing and 300-400MB/s for at least 4 clients is minimum (currently a single windows client gets at least 700/700 for a single client over samba, peaking to 950 at times using blackmagic speed test). Gluster has been getting me as low as

I've been reading this group for a while and I've noticed a variety of comments regarding running OCFS on top of path-management packages such as EMC's Powerpath, and it brought to mind a problem I've been having. I'm currently testing a six-node cluster connected to a Hitachi 9570V SAN storage array, using OCFS 1.0.12. I have six LUNs presented to the hosts using HDLM,

Hi guys I have met some troubles when I want to evaluate the glusterfs performance with small file workload. 1: What kind of benchmark should I use to test the small file operation ? As we all know, we can use iozone tools to test the large file operation, while for the sake of memory cache, if we testing small file operation with iozone, the result will not correct.

Hello Jeremy, > OH - that's *really* interesting ! I wonder how it is > changing the SMB3+ redirector to do this ? It looks like applications could do something and give a hint to SMB3+ redirector, so far not quite sure how to make it, per process monitor (procmon) could show that write I/O size seems could be pass from the application layers,

Hello Ivan, 'FastCopy' has an option to revise max I/O size and works for SMB :) it is a tool for file transferring and could be installed to win10, download here: https://fastcopy.jp/ This is an example for writing, a job would write a file named '1GB.img' from a local disk 'H:' to a remote SMB mounted net disk 'Z:', open 'FastCopy' tool and specify

Dear ALL, IHAC who would like to use Sun Fire X4500 to be the NFS server for the backend services, and would like to see the potential performance gain comparing to their existing systems. However the outputs of the I/O stress test with iozone show the mixed results as follows: * The read performance sharply degrades (almost down to 1/20, i.e from 2,000,000 down to 100,000) when the

Hi Matt, Can you please provide us with more information? 1. what version of glusterfs are you using 2. Was the iozone run as root or user? a. if user, did it have the required permissions? 3. steps to reproduce the problem 4. Any other errors related to stripe in the clinet log?

Hi guys, I have spent many days on debuging read/write performance of glusterfs with samba-gluster-vfs plugin recently. The write performance is okay, but the read speed is always dispirited. The testing environment is like this: OS: centos 6.4 hosts: two hosts, one for samba server which glusterfs with samba-glusterfs-vfs runs on it, the other for samba client glusterfs version:

It's a pity I don't know how to re-create the issue. While there are 1-2 crashed clients in total 120 clients every day. Below is gdb result: (gdb) where #0 0x0000003267432885 in raise () from /lib64/libc.so.6 #1 0x0000003267434065 in abort () from /lib64/libc.so.6 #2 0x000000326746f7a7 in __libc_message () from /lib64/libc.so.6 #3 0x00000032674750c6 in malloc_printerr () from
