with 'mtu 9000' set in /etc/network/interfaces , jumbo needed to be set on the switch. that fixed all our issues. note this was not a multi cast issue. in addition nfs clients could not access nfs mounts so to enable mtu 9000 on the switch: telnet@quanta-1#configure terminal...

Note after setting up brocade firmware - as you predicted - we have the same issue. before doing that we'd tried a lot of things . so will of course continue to debug until fixed. also thank you for the Brocade TurboIron firmware . these are great switches with now excellent software...

Will I tried using the stock firmware - cluster communications issue I could not solve. I tried setting up IGMP snooping and Multicast . Searched , tried settings etc.. anyway I'll change to Brocade as I have documentation for setting up igmp etc. I knew you were just dying to know that.

also this was the network config , the only difference from the normal one used is the address #iface enp129s0f0 inet manual #iface enp129s0f1 inet manual #auto bond2 #iface bond2 inet static # address 10.11.12.2 # netmask 255.255.255.0 # slaves enp129s0f0 enp129s0f1 #...

thank you for the reply. It could very well have been a configuration issue. It was almost working, drives mounted, multicast test worked. I may give it another try . Multicast tests worked [ very fast ] . ceph drives mounted. I'll check logs and try to debug. I did have...

I tried using native firmware with ceph cluster. there were cluster communication issues. after an hour - gave up. next will install Brocade TurboIron firmware.

New Question - we just received two Quanta LB6M - that we will use for a ceph storage network. The network does not need vlans or routing etc. I've read a lot of people change the firmware to something else. For our use - are there speed and reliability or other good reasons to...

searched and found a connections is needed. We've done this before - it was at the end of one of those really long days when i asked.. so for anyone reading my question in the future: https://www.kernel.org/doc/Documentation/networking/bonding.txt 11.2 High Availability in a Multiple...

with active/backup and non stacking switches - does a patch cable need to connect the two switches? the two switches are for an isolated storage network.

thanks, active/backup is all we need.

I assume then linux bond is not possible using two non stacked switches. hopefully am I wrong?

Hello tjk - thank you for the fast response you wrote ' LB8M' we have LB6M . Which I assume is the same - not stackable.

Are these switches stackable? Looking to set up LAGS between switches for linux network bonding.

Hello Terry Wallace. It is for future proofing. I based my decision on the following: the refurbished X5's are reasonably priced . the latest Mellanox IB linux driver does not support ConnectX-2 . See release notes at...

I spoke to Mellanox pre sales support - and standard sfp+ cables will work. So will purchase ConnnectX-5 cards .

We have ordered two Quanta LB6M switches. These will be used in an existing 7 node proxmox cluster using 65 400GB SSD's . data: pools: 2 pools, 1088 pgs objects: 137.66k objects, 498GiB usage: 1.46TiB used, 24.1TiB / 25.5TiB avail Disk i/o is very low. Our goal is to...

also for ceph I use a cronjob to check for slow requests. on the average they occur for 15 seconds per day. I'll notice them if doing cli work there will be a lag. these can affect data file writes - especially on a system that needs to run on linux 2.6 . the slow requests normally occur...

We are using the intel driver / modules which come with latest Proxmox / Debian . I'll check in to using latest stable drivers from Intel. Thank you for the suggestion.

Hello to increase our proxmox ceph storage cluster reliability, I'm looking to upgrade ceph network from Intel 10G ethernet to SFP+ . we have an issue with slow requests , much like this person had Ceph, SolarFlare and Proxmox – slow requests are blocked . the issue has been going on...
