Hi list! First of all sorry for breaking the thread, but I wasn''t subscribed when the orignal messages were posted. I''m continuing this message http://lists.xensource.com/archives/html/xen-users/2010-11/msg00166.html I''m 100% sure that a fresh install of Squeeze (as of last week) with Xen 4.0.1 and Debian''s -xen-amd64 kernel results in an early reboot on a

I've tested about 12 different Dell servers. Ony a couple of them have Idrac express and all the others have Idrac Enterprise. All the boxes with Enterprise perform poorly and the couple that have express perform well. I use the disks in raid mode on all of them. I've tried a few non-Dell boxes and they all perform well even though some of them are very old. I've also tried

Thanks for the suggestion. I tried both of these with no difference in performance.I have tried several other Dell hosts with Idrac Enterprise and getting the same results. I also tried a new Dell T130 with Idrac express and was getting over 700 MB/s. Any other users had this issues with Idrac Enterprise??

I don't think it is related with iDRAC itself but some configuration is wrong or there is some hw error. Did you check battery of raid controller? Do you use disks in jbod mode or raid mode?

I would be really supprised if the problem was related to Idrac. The Idrac processor is a stand alone cpu with its own nic and runs independent of the main CPU. That being said it does have visibility into the whole system. try using dmidecode to compare the systems and take a close look at the raid controllers and what size and form of cache they have.

What is your gluster setup? Please share volume details where vms ate stored. It could be that the slow host is having arbiter volume.

I have a 3 host gluster replicated cluster that is providing storage for our RHEV environment. We've been having issues with inconsistent performance from the VMs depending on which Hypervisor they are running on. I've confirmed throughput to be ~9Gb/s to each of the storage hosts from the hypervisors. I'm getting ~300MB/s disk read spead when our test vm is on the slow Hypervisors

All volumes are configured as replica 3. I have no arbiter volumes. Storage hosts are for storage only and Virt hosts are dedicated Virt hosts. I've checked throughput from the Virt hosts to all 3 gluster hosts and am getting ~9Gb/s. On Tue, Feb 27, 2018 at 1:33 AM, Alex K <rightkicktech at gmail.com> wrote: > What is your gluster setup?

"Did you check the BIOS/Power settings? They should be set for high performance. Also you can try to boot "intel_idle.max_cstate=0" kernel command line option to be sure CPUs not entering power saving states.

Hi list, It appears there is a problem with the OpenMPI I/O library on CentOS 6.2 & 6.3 (package openmpi-1.5.4-1.el6.x86_64). When I compile the attached program it ends up in the error path since MPI_File_open returns 16. The corresponding (unhelpful) message is: MPI_ERR_OTHER: known error not in list I couldn't find any pointers on the net and the same program works with OpenMPI

Bonjour, J''aimerai mettre en place un cluster sous Xen ou XenServer avec 2 serveurs dell R 710. J''aimerai pouvoir monter un cluster en utilisant l''espace disque entiere des 2 serveurs cumulés ainsi que la mémoire Quelles sont vos retour d''expériences et vos configurations? Merci d''avance Cordialement Mat

Hi, I'm trying to compile two functions into one function. the first funtion is called 'fs' which is self-made function, another function is from the built-in 'integration' function that is copy-paste-edited. If built separatey, these functions work well. However that is not the case if combines together, where certainly I made mistake somewhere when constructing the code.

Trying to connect to a Dell iDRAC 6. The iDRAC reports it is running OpenSSH 5.2. From Fedora Linux 20 with OpenSSH 6.4p1, connections succeed. From Fedora Linux 23 with OpenSSH 7.2p2, connections succeed. From Fedora Linux 27 with OpenSSH 7.6p1, connections fail prior to prompting for a password. The message is, "Received disconnect from (IP address) port 22:11: Logged out." Trying

I've only been using R on and off for 9 months and started using the glasso package for sparse covariance estimation. I know the concept is to shrink some of the elements of the covariance matrix to zero. However, say I have a dataset that I know has some underlying "baseline" covariance/correlation (say, a value of 0.3), how can I change or incorporate that into to the

hi,all. I found that use the ps -ef command to check a service status have some error. I test it . run puppetd --debug --tags apache2 ,get this message. ============= debug: Service[apache2](provider=debian): Executing ''ps -ef'' debug: Service[apache2](provider=debian): PID is 12062 ============ but the apache2 service is not running. and if I run ps -ef|grep apache2

I have a need to display text to COM2 before loading a kernel. The easiest way to do this was to invade menu.c32 (menumain.c) and add a function to send the string out to the serial port just before the selected menu "label" is executed. In menumain.c, my function is called just before 'if (cmdline)'. The code I wrote to initialize the hardware and send individual characters

We are having problems building R on Red Hat Linux 6.0/Sparc. R compiles with no problem but then it fails "make tests". Specifically, the line eigen(cbind(-1,c(1:2,0),0:2)) # complex values causes a segmentation fault. Previous versions of Red Hat Linux did not give this problem. The eigen() function is one of the rare cases in the base library where Fortran code is called via the

Hi, I noticed a minor flaw in integrate() from package stats: Taking up arguments lower and upper from integrate(), if (lower == Inf) && (upper == Inf) or if (lower == -Inf) && (upper == -Inf) integrate() calculates the value for (lower==-Inf) && (upper==Inf). Rather, it should return 0. Quick fix: ### old code ### ### [snip] else {
