Hi Consider the typical spit brain situation: reading from file gets EIO, logs say: [2011-08-21 13:38:54.607590] W [afr-open.c:168:afr_open] 0-gfs-replicate-0: failed to open as split brain seen, returning EIO [2011-08-21 13:38:54.607895] W [fuse-bridge.c:585:fuse_fd_cbk] 0-glusterfs-fuse: 1371456: OPEN() /manu/netbsd/usr/src/gnu/dist/groff/doc/Makefile.sub => -1 (Input/output

Hello gluster-verse! I'm about to see if GlusterFS can handle a large amount of clients, this was not at all in plans when we initially selected and setup our current configuration. What sort of experience do you (the collective "you" as in y'all) have with a large client to storage brick server ratio? (~1330:1) Where do you see things going awnry? Most of this will be reads

I'm trying to manually garbage data on bricks (when the volume is stopped) and then check whether healing is possible. For example: Start: # glusterd --debug Bricks (on EXT4 mounted with 'rw,realtime'): # mkdir /root/data0 # mkdir /root/data1 # mkdir /root/data2 Volume: # gluster volume create gv0 replica 3 [local-ip]:/root/data0 [local-ip]:/root/data1 [local-ip]:/root/data2

I'm building a two node cluster to run vserver systems on. I've setup glusterfs with this config: # node a volume data-posix type storage/posix option directory /export/cluster end-volume volume data1 type features/posix-locks subvolumes data-posix end-volume volume data2 type protocol/client option transport-type tcp/client option remote-host

OK - finished some tests over tcp and ironed out a lot of problems. rdma is next; should be snap now.... [I must admit that this is my 1st foray into the land of IB, so some of the following may be obvious to a non-naive admin..] except that while I can create and start the volume with rdma as transport: ================================== root at pbs3:~ 622 $ gluster volume info glrdma

Hi Soumya, We just had the opportunity to try the option of disabling the kernel-NFS and restarting glusterd to start gNFS. However the gluster demon crashes immediately on startup. What additional information besides what we provide below would help debugging this?

Hello, I am using Dotplot (from Frank Harrell's HMISC library) to make a graph of rates with confidence intervals but I get a 'black' background -- nice but not on a printed document: >Dotplot(group~Cbind(rate,lower,upper)|mortality,data=mort,ylab=' ') How do I change the background (and other) collors in Dotplot? Thanks for you help. Marwan Khawaja platform

Hi, We noticed a dramatic slowness when writing to a gluster disk when compared to writing to an NFS disk. Specifically when using dd (data duplicator) to write a 4.3 GB file of zeros: * on NFS disk (/home): 9.5 Gb/s * on gluster disk (/gdata): 508 Mb/s The gluser disk is 2 bricks joined together, no replication or anything else. The hardware is (literally) the same: * one server with

Are you sure using conv=sync is what you want? I normally use conv=fdatasync, I'll look up the difference between the two and see if it affects your test. -b ----- Original Message ----- > From: "Pat Haley" <phaley at mit.edu> > To: "Pranith Kumar Karampuri" <pkarampu at redhat.com> > Cc: "Ravishankar N" <ravishankar at redhat.com>,

Hi Ben, Sorry this took so long, but we had a real-time forecasting exercise last week and I could only get to this now. Backend Hardware/OS: * Much of the information on our back end system is included at the top of http://lists.gluster.org/pipermail/gluster-users/2017-April/030529.html * The specific model of the hard disks is SeaGate ENTERPRISE CAPACITY V.4 6TB

Hello, I get a nice looking barplot using the barplot2 function in the gregmisc package: body2 <- barplot2(hh3, beside = TRUE, col = c("mistyrose", "lightcyan"), .... cex.names = 1.0, plot.ci = TRUE, ci.l = cil, ci.u = ciu, plot.grid = TRUE) box() However, obviously I lose the collors when converting from ps to a pdf (outside of R)

Hello, I have 15 data points (weight at birth) by age which I want to interpolate back in time (to 5 more age points). There are many functions in R to do this and I wonder if anyone has experience in using these -- any preference/caveat etc? I am trying to find an alternative to linear interpolation. Using R 1.6.0 under windows TIA Marwan

Hi All, Decided to try another tests of gluster mounted via FUSE vs gluster mounted via NFS, this time using the software we run in production (i.e. our ocean model writing a netCDF file). gluster mounted via NFS the run took 2.3 hr gluster mounted via FUSE: the run took 44.2 hr The only problem with using gluster mounted via NFS is that it does not respect the group write permissions which

Hi Guys, I was wondering what our next steps should be to solve the slow write times. Recently I was debugging a large code and writing a lot of output at every time step. When I tried writing to our gluster disks, it was taking over a day to do a single time step whereas if I had the same program (same hardware, network) write to our nfs disk the time per time-step was about 45 minutes.

Hi, Today we experimented with some of the FUSE options that we found in the list. Changing these options had no effect: gluster volume set test-volume performance.cache-max-file-size 2MB gluster volume set test-volume performance.cache-refresh-timeout 4 gluster volume set test-volume performance.cache-size 256MB gluster volume set test-volume performance.write-behind-window-size 4MB gluster
