A newish kernel+e2fsprogs supports ext4 volumes > 16TB.

Beware though, > 16TB is relatively new you may run into problems (I did in the past with a 60TB volume).

I’d recommend looking at using XFS or, if EXT4 is needed, use volumes less than 16TB.


Also I would not necessarily recommend it but you could create an mdadm-RAID 0 of the two volumes and format it as XFS, but you would be putting all of your eggs in one basket, e.g. if one of the 20 x 2.5TB LUNs failed, you would lose all of the data.

Just want to create a  to on my Redhat (REL5) Linux Media Server Creating file system for my MSDP pool, a 50TB (20 x 2.5TB LUNs).

- And put it firmly that the ext4 file system sizes up to 16TB only unsterstützt.

We have solved that?

-> Is there a way the MSDP "foist" multiple file systems?

-> Do you use Redhat Linux filesystems> 16TB

- >> If yes, which file system you use?
