Da un'analisi su cloud-juno-nova03 (compute node dedicato a BIOPHYS) è emerso che le CPU non sono mai in idle state C0, ma sono sempre in C1 o addirittura C2 (che ha una transition latency di 100 ms) e che la frequenza a cui operano le CPU è 1.4 text/html 2020-02-06T07:36:32+00:00 Anonymous (anonymous@undisclosed.example.com) Error Creating Inf.: Invalid credentials with the provider https://wiki.infn.it/strutture/cnaf/cloud_cnaf/admins_corner/troubleshooting/error_creating_inf?rev=1580974592&do=diff Error Creating Inf.: Invalid credentials with the provider Reproducubility High Command #curl -L -i -H 'Content-type: text/yaml' -H "Authorization: id = ost; type = OpenStack; host = https://horizon.cloud.cnaf.infn.it:5000/v3; username = indigo-dc; password = $IAM_ACCESS_TOKEN; tenant = oidc; auth_version = 3.x_oidc_access_token; service_region = regionOne;\nid = im; type = InfrastructureManager; token = $IAM_ACCESS_TOKEN" -X POST https://im-dodas.cloud.cnaf.infn.it/infrastructures --data… text/html 2020-02-05T07:09:55+00:00 Anonymous (anonymous@undisclosed.example.com) Problemi con ISCSI su nodo oVirt https://wiki.infn.it/strutture/cnaf/cloud_cnaf/admins_corner/troubleshooting/iscsi_ovirt?rev=1580886595&do=diff Problemi con ISCSI su nodo oVirt Notifiche problemi Soluzioni problemi [root@oneprovider-cnaf ~]# systemctl status iscsi ● iscsi.service - Login and scanning of iSCSI devices Loaded: loaded (/usr/lib/systemd/system/iscsi.service; enabled; vendor preset: disabled) Active: active (exited) since Mon 2018-10-08 16:10:46 CEST; 1 weeks 2 days ago Docs: man:iscsid(8) man:iscsiadm(8) Process: 1305 ExecReload=/sbin/iscsiadm -m node --loginall=automatic (code=exited, status=…
