Jep, 4 TB it is ;)
64k!? I had to act fast so I didn't have the time to check all mkfs 
options. As I read about the "-T mail" option I thought it would choose 
sensible values for creating the FS. All the files are around 12-15 kB 
in size and the blocksize was 4 kB as in the XFS filesystem we use.

Blocksize I understand but what means cluster size in this context (I 
read the man page but couldn't wrap my head around it).
Still it seems that reformatting is my only choice since I don't have 
enough space with the current setup. *argh*
Yeah, I know RTFM.

Thanks,
