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.

Fixing a https Cert in Windows

 I renewed a https cert today in Windows and had problems with the new Cert sticking in Windows It would add fine, without error, but would disappear when the IIS Server Certificates screen would refresh.  Open the Certificates in MMC (Local Machine) and inspecting the Web Hosting gave a clue, the new certificate was there, but with a key - the private key was missing.  Could be because the original certificate was created on a completely different machine and imported to this new server.  At any rate, a simple certutil command fixed it .  A tip I received from  SSL disappears from the certificate list on Windows server - SSL Certificates - Namecheap.com Key steps are:  Double-click the certificate and go to  Details  tab. In certificate details locate the  Serial Number  field, click on it and copy its value. Open Command Prompt, pressing  Win+R  and typing  cmd , then click  OK In the command prompt type: ...

Ever need to reset a password in Bonobo Git Server ?

So, you've forgotten your password to bonobo git. Step 1: Get access to the sqlite file, probably called something like  Bonobo.Git.Server.db, sitting in the "wwwroot\Bonobo.Git.Server\App_Data" directory. Step 2: Using another tool, generate an md5 hash of your new desired password (as far as I know, sqlite does not have md5 capability) Step 3: Back in sqlite, using SQL, update the relevant user record, something like update User set Password = UPPER( 'thenewMD5hash') where Username = 'admin' ; Step 4: That's it, you are done, log in with your newly found password.

Save Attachments in Outlook automatically

For years I have wanted something to do this, and finally found it. Worked perfectly for me in Outlook 2013  In the end it is so simple. Guide from http://www.pixelchef.net/content/rule-autosave-attachment-outlook and https://msdn.microsoft.com/en-us/library/ee814736.aspx Open the VBA IDE in Outlook. Alt-F11 will do this. Insert the following code to the Modules section. On the left side there is a tree, expand until you find Modules. Then, if there is not a Module item under Modules, create one by right clicking on Modules. Or right click and choose Insert -> Module. Now, paste the text below in the main VBA window. Close the VBA IDE. Create a Rule that calls the script. Tools -> Rules and Alerts -> New Rule... In the first screen of the new rule wizard, choose "Check messages when they arrive". In the second, you could specify certain criteria that the message must match. Tip: Try "with specific words in the message header" and ...
