similar to: Status of DTrace NFSv3/v4 client providers

Hi, I am adding DTrace probes within NFS v3 client. In my current implementation, I use some tsd_*() functions and kmem_zalloc() function. These functions might be heavy and affect the performance. I want to call this function only when DTrace is running or the DTrace probes are enable. So is there a way to check DTrace is running or DTrace probe is enabled? Regards, Danhua

Hi, Thanks for the comment for my nfsv3client probe implementation! I have made changes accordingly. Webrev: http://cr.opensolaris.org/~danhua/webrev/ To reduce the overhead, I use a local variable to save XID, rather than alloc memory space with kmem_zalloc(). According to the overhead caused by tsd_get() and tsd_set(), I did an experiment to measure it. In this experiment, I run a dtrace

Hello, I saw that parallel-readdir was an experimental feature in GlusterFS version 3.10.0, became stable in version 3.11.0, and is now recommended for small file workloads in the Red Hat Gluster Storage Server documentation[2]. I've successfully enabled this on one of my volumes but I notice the following in the client mount log: [2018-01-23 10:24:24.048055] W [MSGID: 101174]

Thank you, Raghavendra. I guess this cosmetic fix will be in 3.12.6? I'm also looking forward to seeing stability fixes to parallel-readdir and or readdir-ahead in 3.12.x. :) Cheers, On Mon, Jan 29, 2018 at 9:26 AM Raghavendra Gowdappa <rgowdapp at redhat.com> wrote: > > > ----- Original Message ----- > > From: "Pranith Kumar Karampuri" <pkarampu at

By the way, on a slightly related note, I'm pretty sure either parallel-readdir or readdir-ahead has a regression in GlusterFS 3.12.x. We are running CentOS 7 with kernel-3.10.0-693.11.6.el7.x86_6. I updated my servers and clients to 3.12.4 and enabled these two options after reading about them in the 3.10.0 and 3.11.0 release notes. In the days after enabling these two options all of my

Dear Vlad, I'm sorry, I don't want to test this again on my system just yet! It caused too much instability for my users and I don't have enough resources for a development environment. The only other variables that changed before the crashes was the group metadata-cache[0], which I enabled the same day as the parallel-readdir and readdir-ahead options: $ gluster volume set homes

Hello, ? ? Will we also suffer from this regression in any of the (previously) fixed 3.10 releases?

Ouch! Yes, I see two port-related fixes in the GlusterFS 3.12.3 release notes[0][1][2]. I've attached a tarball of all yesterday's logs from /var/log/glusterd on one the affected nodes (called "wingu3"). I hope that's what you need.

Dear list, I noticed that GlusterFS 11 introduces a new "simple quota" system. According to the pull request? the implementation is based on Amar's earlier proposal? and is inspired by work they did in Kadalu. Other than that I don't see any documentation or discussion about these features. Specifically, it seems that the implementation relies on the quota features of the

can you please test parallel-readdir or readdir-ahead gives disconnects? so we know which to disable parallel-readdir doing magic ran on pdf from last year https://events.static.linuxfound.org/sites/events/files/slides/Gluster_DirPerf_Vault2017_0.pdf -v On Thu, Jan 25, 2018 at 8:20 AM, Alan Orth <alan.orth at gmail.com> wrote: > By the way, on a slightly related note, I'm pretty

So from the logs what it looks to be a regression caused by commit 635c1c3 ( and the good news is that this is now fixed in release-3.12 branch and should be part of 3.12.5. Commit which fixes this issue: COMMIT: https://review.gluster.org/19146 committed in release-3.12 by \"Atin Mukherjee\" <amukherj at redhat.com> with a commit message- glusterd: connect to an existing brick

3.10 doesn't have this regression, so you're safe.

Hi, lme() users, Can some one tell me how to do this. I model Orthodont with the same G for random variables, but different R{i}'s for boys and girls, so that I can get sigma1_square_hat for boys and sigma2_square_hat for girls. The model is Y{i}=X{i}beta + Z{i}b + e{i} b ~ iid N(0,G) and e{i} ~ iid N(0,R{i}) i=1,2 orth.lme <- lme(distance ~ Sex * age, data=Orthodont, random=~age|Subject,

Dear list, In a recent discussion on this list Ravi suggested that the documentation for replace-brick? was out of date. For a distribute?replicate volume the documentation currently says that we need to kill the old brick's PID, create a temporary empty directory on the FUSE mount, check the xattrs, replace-brick with commit force. Is all this still necessary? I'm running Gluster 5.6 on

Hi, I have a 2-node replica volume running with GlusterFS 3.3.2 on Centos 6.4. I want to shut down one of the gluster servers for maintenance. Any best practice that is to be followed while turning off a server in terms of services etc. Or can I just shut down the server. ?
