Criando zfs proxmox backup

primeiro tem que zerar os discos.

sgdisk –zap-all /dev/sdc

segundo tem que dar um boot no servidor para reconhecer os disco como limpo sem partição.

logo apos voltar.

zpool create -f -o ashift=12 RAID0 /dev/sdb /dev/sdc

pronto teu zfs esta criado com raid0 no comando acima.

para montar o raid0

crie um ponto de montagem no meu caso foi /backup

zfs set mountpoint=/backup RAID0

Squid Proxy on pfSense for Home Web Cache and Security

About my setup

I have a pfSense box running 2.2.5-RELEASE (amd64), Squid 3.4 branch, and SquidGuard.

To customize the refresh rules, go to Services menu, select Squid proxy. Select the Local cache tab.

More details

To make the cache more aggressive, i used (\?|$). by adding /?, this caches objects when the URL ends in ? (example abc.css?). Typically a ? is used to indicate dynamic content, and is also used to instruct caches to NOT cache those objects, so be careful using this. However, I found it is OK to ignore the ? after objects like jpgs and css, and many times js. These objects are static content, and most of the time they do not change and can be cached for long periods of time. Caching these kinds of objects is great, because it reduces the number of requests you make to the web. I also use the $ option above. This means its the end of the string, so \.jpg$ just matches an object with .jpg at the end of the URL.

I use a catch all. The function of this rule is to match any requests that have not already matched the rules above. Be careful here, because this rule can/will cache dynamic content. The default pfsense Squid catchall exists in the default config already, however, the built-in config is not editable (as far as I understand). It will always revert to default (let me know if you know how to change that). Thus, to work-around I can simply add and customize the catch all at the bottom of my “Custom refresh_patterns”.
