Drobo FS format type

I recently got a new FS - threw in 2 drives I had lying around (they had some data on it, but I don’t know what format or what it was – didn’t care).

Never once during the install (which went fine) or anything was I asked what format to use for the drives.

Things seem to be working, but how can I tell which format it’s using? I plan on moving a TON of data to the Drobo, but don’t want to later find out it’s using FAT32 or something instead of HFS+ (I’m an all Mac guy)…

Where/how can you see what type it’s using?

Since you’re connecting to it over the network the details don’t matter so much, but for your edification it’s using ext3.

Awesome - that definitely answers my question! Thanks for the quick reply!

A side note for any admins that may monitor this – the information spattered across the site and support and even help guides are very unclear about this (how the FS is very different in terms of formatting and such) than the others. I suspected as much, but couldn’t find this info anywhere.


The format is really pretty much irrelevant. As @noidd says, you’re accessing it over the network at all times, there’s no way to direct-conect the FS so all you ever see is a Windows or Mac fileshare. Don’t sweat it.

By the way, if you use the Dashboard to mount the shares I think they mount as SMB (i.e. Windows file shares). If you want them to mount AFP (Mac filesharing) I think you need to mount them via Command-K in the Finder.

Type “mount” in a terminal and the output should tell you how they are mounting.

On dashboard 1.7.2, shares on a mac are mounting via AFP.

Very good!

The dashboard mounting doesn’t work for me, unfortunately (v1.7.2), but I remember reading in another thread that it was a known issue and would be fixed in the next release. Hope so!
