Hi all I want to configure glusterfs to expose iSCSI target. I followed this artical https://pkalever.wordpress.com/2016/06/23/gluster-solution-for-non-shared-persistent-storage-in-docker-container/ but when I install tcmu-runner. It doesn't work. I setup on CentOS7 and installed tcmu-runner by rpm. When I run targetcli, it not show *user:glfs* and *user:gcow* */>* ls o- / ......................................................

And the sad part is we haven't tested gluster-block on centos, but just source compile should work IMO. > I want to configure glusterfs to expose iSCSI target.

Hi Kalever! First of all, I really appreciate your test results for block-store(https://github.com/pkalever/iozone_results_gluster/tree/master/block-store) :-) My teammate and I tested block-store(glfs backstore with tcmu-runner) but we have met a problem of performance. We tested some cases with one server that has RDMA volume and one client that is connected to same RDMA network. two machines have same environment like below. - Distro : CentOS 6.9 - Kernel : 4.12.9 - GlusterFS : 3.10.5 - tcmu-runner : 1.2.0 - i...

Dear Sirs, The below listed code fits a gamma and a pareto distribution to a data set danishuni. However the distributions are not appropriate to fit both tails of the data set hence a mixed distribution is required which has ben defined as "mixgampar" as shown below. library(fitdistrplus) x<- danishuni$Loss fgam<- fitdist(x,"gamma",lower=0) fpar<-

I have attempted to install the packages Rtools and rgrs but the install.packages command yields a message that the same are not available for R version 4.0. How do i get around this as i need the said packages to implement some credit scoring GLMs using the " rgrs" package. With Regards, Charles [[alternative HTML version deleted]]
