Gluster & Hyper Converged setup

Hi, Gluster will not set up and fails... can anyone see why ? /etc/hosts set up for both backend Gluster network and front end, also LAN DNS set up on the subnet for the front end.

Wrong CPU?

Hey folks, running an AMD Ryzen CPU here: processor : 0 vendor_id : AuthenticAMD cpu family : 23 model : 49 model name : AMD EPYC 7282 16-Core Processor However, libvirt is detecting this as EPYC-IBPB without the ssbd flags? <cpu> <arch>x86_64</arch> <model>EPYC-IBPB</model> <vendor>AMD</vendor> <microcode version='137367580'/> <counter name='tsc' frequency='2799999000'/> <topology sockets='1' cores='16' threads='2'/> <feature name='ht'/> <feature name='osxsave'/> <feature name='cmt'/> <feature name='clwb'/> <feature name='umip'/> <feature name='xsaves'/> <feature name='mbm_total'/> <feature name='mbm_local'/> <feature name='cmp_legacy'/> <feature name='extapic'/> <feature name='ibs'/> <feature name='skinit'/> <feature name='wdt'/> <feature name='tce'/> <feature name='topoext'/> <feature name='perfctr_core'/> <feature name='perfctr_nb'/> <feature name='invtsc'/> <feature name='wbnoinvd'/> <pages unit='KiB' size='4'/> <pages unit='KiB' size='2048'/> <pages unit='KiB' size='1048576'/> </cpu> [root@node01 ~]# grep ssbd /var/cache/libvirt/qemu/capabilities/*.xml <property name='ssbd' type='boolean' value='false'/> <property name='virt-ssbd' type='boolean' value='false'/> <property name='ssbd' type='boolean' value='false'/> <property name='virt-ssbd' type='boolean' value='false'/> But the flag is there: [root@node01 ~]# grep ssbd /proc/cpuinfo | tail -n1 flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm constant_tsc art rep_good nopl xtopology nonstop_tsc extd_apicid aperfmperf eagerfpu pni pclmulqdq monitor ssse3 fma cx16 sse4_1 sse4_2 movbe popcnt aes xsave avx f16c rdrand lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs skinit wdt tce topoext perfctr_core perfctr_nb bpext perfctr_l2 cpb cat_l3 cdp_l3 hw_pstate sme retpoline_amd ssbd ibrs ibpb stibp vmmcall fsgsbase bmi1 avx2 smep bmi2 cqm rdt_a rdseed adx smap clflushopt clwb sha_ni xsaveopt xsavec xgetbv1 cqm_llc cqm_occup_llc cqm_mbm_total cqm_mbm_local clzero irperf xsaveerptr arat npt lbrv svm_lock nrip_save tsc_scale vmcb_clean flushbyasid decodeassists pausefilter pfthreshold avic v_vmsave_vmload vgif umip overflow_recov succor smca I tried adding "options kvm_amd avic=1" as well as "options kvm_amd avic=0" to /etc/modprobe.d/kvm.conf (always with reboots), adding mitigations=off to grub.. I can't think of any other solution. I just can't get the oVirt engine running with the ssbd flag. Seems cpu can do this, oVirt can do this, libvirt does not detect the cpu correctly or at least ignores it. But the hosted engine demands it. I am at a loss.

Gluster setup
by rob.downer＠orbitalsystems.co.uk 18 Nov '19

18 Nov '19

I have set up a 3 node system. Gluster has its own backend network and I have tried entering the FQDN hosts via ssh as follows... gfs1.gluster.private 10.10.45.11 gfs2.gluster.private 10.10.45.12 gfs3.gluster.private 10.10.45.13 I entered at /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 gfs1.gluster.private 10.10.45.11 gfs2.gluster.private 10.10.45.12 gfs3.gluster.private 10.10.45.13 but on the CLI host gfs1.gluster.private returns [root@ovirt1 etc]# host gfs1.gluster.private Host gfs1.gluster.private not found: 3(NXDOMAIN) [root@ovirt1 etc]# I guess this is the wrong hosts file, resolver.conf lists files first for lookup...

Re: SSBD issues on live cluster

Copy the long xml and save it to a file. Then edit and remove the requirement for the mitigations. Then set the following alias: alias virsh='virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf' Then : virsh undefine HostedEngine virsh define <file> virsh start HostedEngine Maybe it will work :) Best Regards, Strahil NikolovOn Nov 15, 2019 15:30, Christian Reiss <email(a)christian-reiss.de> wrote: > > On 15/11/2019 13:30, thomas(a)hoberg.net wrote: > > Since there is no guarantee that the oVirt node image and the hosted-engine image are aligned, I'd recommend disabling all mitigations during the host's boot (only got a list of the Intel flags, sorry: Not rich enough for EPYC) and see if that sails through.

In /etc/hosts you first enter the IP then FQDN, and last shortname (aliases). Fix the /etc/hosts file !

Ovirt can use VDO for deduplication and compression, but I think it was related to ZFS.
