Drobo: Thin Provisioning

If you know me, you know that I’m a huge proponent of Drobo.  As of late, the frustration level with Drobo is increasing and it may have edged away at this enthusiasm.

My most recent frustration came when I upgraded a drive in my Drobo to increase the usable space to more then 2TB.  After the Drobo finished updating all of its partitions, I was left with a partition that was labeled ‘unallocated’ in the Drobo dashboard.  After searching the interwebs (which yielded absolutely nothing on Drobo’s site for ‘unallocated’) and posting on a couple of forums, I was led to this:

This is telling me that I’m stuck with adding partitions to my Drobo of maximum size 2TB because of a decision I made when I originally set it up, at which time I was not told how this setting would affect me as I add disk space.  Further, I think that Drobo’s claims of being both “simple” and “scalable” are misleading as this limitation is not spelled out up-front and if you don’t understand this, the affects of scaling can be considerably different then what is expected.

Now that I have have realized this, the only way to have 1 single partition again is to (in Drobo’s own words) “migrate the data onto another Drobo or storage device, reformat the original Drobo device to the volume size of your choice, and then move the data back.”  With 2TBs of data, not only is this a huge pain in the ass, I need to buy another drive in order to fit the entirety of my Drobo on a disk before reformatting.

I think this a huge failure on Drobo’s part that could be fixed one of 2 ways:

  1. Be explicit about how setting this soft limit is actually a hard limit on the amount of space that can be allocated to a volume.
  2. Drobo creates a tool to resize partitions to change storage space on a partition.

A tool in this situation would prove extremely handy and would prevent any confusion or problems when going over this thinly provisioned partition cap.

Any help here, Drobo?

Browsing the web is for saps.

Do you have a specific set of webpages that you browse to every day?

I do.  I used to have all of these sites bookmarked and placed into specific news folders in Firefox or Safari.  Right-clicking on a folder would present the option to ‘Open All in Tabs’ and all of my favorites would be right there for me to filter through.  This was easy to setup and I had all of my regular pages a couple of clicks away.  This system, while it works, has a couple of flaws, the most annoying of which is you have to actually browse to the page in order to determine if it has been updated or not.

Enter RSS

Recently I discovered the power of RSS along with RSS readers.  This changes the ‘pull’ system I was used into a much more manageable and easily aggregated ‘push’ system.  Now, when I want to check the news, I go to Google Reader and all of these favorites are organized by tags.  Each tag shows how many unread stories I have right at the top and clicking on a tag gives the aggregated feed with my unread stories on top, making it easy to see what’s new.

Why Google Reader?

Now, I’ll be the first to admit that Google’s RSS reader is not the easiest to use.  However, once you get a feel for how it works, it’s much better then most (all?) of the other RSS readers out there on the Mac.  The 2 that come closest are NetNewsWire and NewsFire, both of which have issues.

NetNewsWire offers syncing with Google Reader, which is nice.  However, the interface is pretty bad and I’ve heard some horror stories about syncing with Google Reader.

NewsFire, on the other hand, has an excellent interface, which makes it easy to use.  However, it doesn’t offer any syncing capabilities.  This is a deal-breaker for me as I browse the Interwebs both at work as well as on 2 machines at home.

Sticking with Google Reader

If you are someone who generally browses on 1 machine, I would highly suggest NewsFire.  Until NewsFire adds some kind of syncing support (hopefully with Google Reader), I’m sticking with Google Reader, which isn’t a bad thing.

WordPress Security Threat

It’s been posted all over the internet as of late, but I’d like to remind everyone of the security threat to WordPress blogs:

WordPress 2.8.4: Security Release

How to Keep WordPress Secure

From the above links, the way to keep yourself safe from this attack is by upgrading.  Make sure you back your DB beforehand.  The easiest way to backup your DB is via this plugin:

wp-db-backup

The sooner you upgrade, the sooner you are safe from this exploit.

UPDATE Sep 7, 2009 – I found a good article from John Gruber of the Daring Fireball on Security and WordPress:
