I recently encountered a problem with my Drobo under Ubuntu: I created an HFS+ volume from my MacBook Pro, filled it with a lot of files (> 3 TB) over the course of several months, and then realized I couldn’t mount it under Ubuntu. Apparently, hfsplus currently doesn’t support volumes larger than 2 TB, because it tends to corrupt them. I don’t know if/when this bug/limitation will be fixed.
Now, I have a second external drive (4 TB) that I can use to copy all the files on the Drobo. The question is: which filesystem should I use on the Drobo to be able to use it (read/write) from Ubuntu (keeping in mind I will have more than 3 TB of files)?
- ext3, which Drobo supports up to 2 TB only? This is apparently an option, as some users managed to use volumes > 2 TB.
- NTFS, which Drobo supports up to 16 TB?
What do you think? Is there any reason not to use NTFS under Ubuntu?
