[ovirt-users] Re: Gluster volume slower then raid1 zpool speed
well, I just reviewed my previous test and I realized that I made a mistake on the gluster mount test. I had up arrowed the shell history and used of= "/test12.img" instead of "./test12" which meant I was testing on the baremetal root partition even though I had 'cd'ed into the Gluster mount. My "Actual" Gluster results on 1G network 7200 drives are in the 20-24 MB/s range using your values. Sorry for the confusion. Your results are consistent. -wk On 11/26/2020 12:29 AM, Harry O wrote: New results from centos vm on vmstore: [root@host2 ~]# dd if=/dev/zero of=/test12.img bs=1G count=1 oflag=dsync 1+0 records in 1+0 records out 1073741824 bytes (1.1 GB) copied, 26.6353 s, 40.3 MB/s [root@host2 ~]# rm -rf /test12.img [root@host2 ~]# [root@host2 ~]# dd if=/dev/zero of=/test12.img bs=1G count=1 oflag=dsync 1+0 records in 1+0 records out 1073741824 bytes (1.1 GB) copied, 61.4851 s, 17.5 MB/s [root@host2 ~]# rm -rf /test12.img [root@host2 ~]# [root@host2 ~]# dd if=/dev/zero of=/test12.img bs=1G count=1 oflag=dsync 1+0 records in 1+0 records out 1073741824 bytes (1.1 GB) copied, 28.2097 s, 38.1 MB/s ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/JPH2OG6FOB4Y36JJPROWDT6V3WTVOPUX/ ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/ECWDBED7KNG3BLUM22RPM7GLPDTDAAHN/

[ovirt-users] VM memory decrease
I have an 8 node cluster running oVirt 4.4.2, i have noticed lately that some VMs started to have their memory decrease. For example a VM that was configured to have 32GB memory without any notice were had their memory decrease to about 4GB, if i restart the VM the VM comes up with the correct memory but shortly after it decreases again. The VM configuration has: Memory Size: 32768 MB Maximum Memory: 131072 MB Physical Memory Guaranteed: 1024 MB It's worth mentioning that those are Linux VMs which are provisioned through Foreman, Windows VMs are not provisioned from Foreman and their "Memory Size" is identical to "Physical Memory Guaranteed", so far i have not observed a Windows VM with this behaviour, though there might be some that i haven't caught. Is there a possibility the cause for this issue is by having "Physical Memory Guaranteed" set to this low? ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/6I2P5ODKFF7UZN2HGIA526IRDCDH5DXP/
