For my Zabbix server, it's nearly canceling all the benefit of using a dirty bitmap. One thing I've noted, is that I get expected values at least for one guest, running PfSense (where I get ~150MB of dirty blocks each days). Most of my other VM are Linux, I'll check if it could be related to the atime update or something Cheers, Daniel -- [ https://www.firewall-services.com/ ] Daniel Berteaud FIREWALL-SERVICES SAS, La sécurité des réseaux Société de Services en Logiciels Libres Tél : +33.5 56 64 15 32 Matrix: @dani:fws.fr [ https://www.firewall-services.com/ | https://www.firewall-services.com ] _______________________________________________ pve-user mailing list [email protected] https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-user
