similar to: Gluster performance / Dell Idrac enterprise conflict

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'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

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?

Here is info. about the Raid controllers. Doesn't seem to be the culprit. Slow host: Name PERC H710 Mini (Embedded) Firmware Version 21.3.4-0001 Cache Memory Size 512 MB Fast Host: Name PERC H310 Mini (Embedded) Firmware Version 20.12.1-0002 Cache Memory Size 0 MB Slow host: Name PERC H310 Mini (Embedded) Firmware Version 20.13.1-0002 Cache Memory Size 0 MB Slow host: Name PERC H310 Mini

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.

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?

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 am forwarding this for Ryan, @Ryan - did you join the gluster users mailing list yet?

Just a note to pass on in case anyone runs into the same situation. I have a DELL R510 that is running just fine, up until the day that I needed to import a pool from a USB hard drive. I plug in the disk, check it with rmformat and try to import the zpool. And it sits there for practically forever, not responding. The machine still responds to network connections etc., it''s just the

Hello everyone, i just updated from 4.2.1 to 4.2.2.

A bus fatal error was detected on a component at bus 0 device 0 function 0. CPU 1 machine check detected. and plenty of other entries. The machine hardresets then. If i

I am currently using a Dell PowerEdge server R610 with Xen 4.0 installed and the 2.6.31.13 pvops kernel. I am accessing the server console using the iDRAC KVM feature of the dell management console. Does anyone know how to configure the console option in the grub menu so that all the boot messages can be seen on the mgmt console? Currently I can view only the Xen bootup messages if I dont specify

Hi folks, Firstly; apologies in advance for what is a head wrecker of keeping on top of the speculative mitigations and also if this is a duplicate email; my first copy didn't seem to make it into the archive. Also a disclaimer that I may have misunderstood elements of the below but please bear with me. I write this hoping to find out a bit more about the state of the relevant kernel

Hi there - I wanted to know if anyone has used Rails & PHP on the same production server and whether they''ve experienced any problems. I''m looking to install rails on our production soon, however I would like to know if there are any issues I need to be aware about. Many thanks, Jared.

Other than when they''re located in I/O port space, accessing them when in MMIO space (currently) implies usage of some sort of global lock: In -unstable this would be due to the use of vmap(), is older trees the necessary locking was introduced by 2ee9cbf9 ("ACPI: fix acpi_os_map_memory()"). This contention was observed to result in Dom0 kernel soft lockups during the loading of
