similar to: lstat & readlink calls during glusterfsd process startup

I'm running version 3.3.0 on Fedora16-x86_64. The official(?) RPMs ship two init scripts, glusterd and glusterfsd. I've googled a bit, and I can't figure out what the purpose is for each of them. I know that I need one of them, but I can't tell which for sure. There's no man page for either, and running them with --help returns the same exact output. Do they have separate

Could you please response?

Hi Team, Whenever I am performing the IO operation on gluster volume, the loads is getting increase on CPU which reaches upto 70-80 sometimes. when we started debugging, found that the io_worker thread is created to server the IO request and consume high CPU till that request gets completed. Could you please let me know why io_worker thread takes this much of CPU. Is there any way to resole

(Re-CC'd list) I would be interested in both, if possible: To confirm that it's not only my machines that exhibit this behaviour given my settings, and to see what can be achieved with your tuned settings. Thank you!

Hi Niklas, Out of interest have you tried testing performance with performance.stat-prefetch enabled? -- Sam McLeod @s_mcleod https://smcleod.net > On 14 Sep 2017, at 10:42 pm, Niklas Hamb?chen <mail at nh2.me> wrote: > > Hi, > > I have a gluster 3.10 volume with a dir with ~1 million small files in > them, say mounted at /mnt/dir with FUSE, and I'm observing

Hi, I have a gluster 3.10 volume with a dir with ~1 million small files in them, say mounted at /mnt/dir with FUSE, and I'm observing something weird: When I list and stat them all using rsync, then the lstat() calls that rsync does are incredibly fast (23 microseconds per call on average, definitely faster than a network roundtrip between my 3-machine bricks connected via Ethernet). But

Hello, Today while freeing up some space on my OS disk I just discovered that there is a /var/lib/misc/glusterfsd directory which seems to save data related to geo-replication. In particular there is a hidden sub-directory called ".processed" as you can see here:

I did a quick test on one of my lab clusters with no tuning except for quota being enabled: [root at dell-per730-03 ~]# gluster v info Volume Name: vmstore Type: Replicate Volume ID: 0d2e4c49-334b-47c9-8e72-86a4c040a7bd Status: Started Snapshot Count: 0 Number of Bricks: 1 x (2 + 1) = 3 Transport-type: tcp Bricks: Brick1: 192.168.50.1:/rhgs/brick1/vmstore Brick2:

Hello together, the function `Sys.readlink` uses the system's readlink command to resolve symlink paths. On OSX/BSD the command has a different meaning than on Linux [1]. There exists the tool 'realpath', which seems suitable for the task, at least applied at the command line level [2]. It is used in `normalizePath`. I suggest (at least the latter) to * use realpath instead readlink

Hi all, I was thinking we should have a Dir.readlink method that would follow a junction to its destination. Sound good? Is ''readlink'' a good choice? Or should we call it read_junction? Regards, Dan

HI, I encountered the following errors below when using rsync version 2.5.6, with the options: # rsync -avzo --delete /src /dest I invoked rsync as a root user. The source and destination filesystems (both reside on the NFS disks), have been exported with root privileges. 1) This file below does exists, however rsync complained of a "No such file or directory" error: readlink

Hi Ben, do you know if the smallfile benchmark also does interleaved getdents() and lstat, which is what I found as being the key difference that creates the performance gap (further down this thread)? Also, wouldn't `--threads 8` change the performance numbers by factor 8 versus the plain `ls` and `rsync` that I did? Would you mind running those commands directly/plainly on your cluster to

Hello, sorry for not being clear enough. My problem is represented with the following code, running on OSX: mkdir ~/test ln -s ~/test ~/testlink touch ~/test/foo Rscript -e 'Sys.readlink(c("~/test/foo", "~/testlink/foo")); normalizePath(c("~/test/foo","~/testlink/foo"))' I expected `Sys.readlink` to show the same output as `normalizePath`.
