Moving ZFS pools

Moving data from one pool to another - zfs.

Method 1: Assumes you are using the same disks

You can create a pool and use the zpool export option on the system you create the pool on.
Once the disks are attached to the final destination host, you can use the zpool import command to import the dataset.

See: Migrating ZFS Storage Pools

Method 2: Assumes you are using zfs with snapshots.

Method 3: Using rsync


rsync -av --log-file=/mnt/PoolA/rsync.log /mnt/PoolA/Data /mnt/PoolB/Data 

The v switch is verbose, the a switch is "archive"

 -a, --archive
              This  is  equivalent  to  -rlptgoD.  It  is a quick way of saying 
              you want recursion and want to preserve almost everything 
              (with -H being a  notable omission).    The   only  exception 
              to  the  above  equivalence  is  when
              --files-from is specified, in which case -r is not implied.

              Note that -a does not preserve hardlinks, because finding 
              multiply-linked files is expensive. 
              You must separately specify -H.

Tip to create an underline on a heading shorter than the heading itself

You can use a pseudo element with :before (or :after ): h1 { font - weight : 300 ; display : inline - block ; padding - bottom : 5px ; position : relative ; } h1 : before { content : "" ; position : absolute ; width : 50 %; height : 1px ; bottom : 0 ; left : 25 %; border - bottom : 1px solid red ; } http://jsfiddle.net/9e27b/ This is another solution that centers the heading, the problem here is that the underline gets shorter as the column gets shorter. h2 {   display: inline-block;   padding-bottom: 15px;   position: relative;   width: 100% ;   text-align: center; } h2:before{     content: "";     position: absolute;     width: 8%;     height: 1px;     bottom: 0;     left: 46%;     border-bottom: 1px solid red; }

The web.config no extension mime problem Lets Encrypt on IIS/Windows

  Tip when using LetsEncrypt in Windows - Feature Requests - Let's Encrypt Community Support In a paragraph, just use the web.config file to set the mime type, eg...  After trying to figure out why my Lets Encrypt failed to generate in Windows, and discovering that it's the no extension mime type problem, I wondered whether certbot could fill in the missing gap. All that is needed is the following web.config file to be placed in the same directory as the challenge <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <staticContent> <mimeMap fileExtension="." mimeType="text/xml" /> </staticContent> </system.webServer> </configuration> Because there's no mime type for files without an extension on IIS, IIS sends back a 404 when verification happens. The web.config file above sets the mime type. After I created the .well-known
