Hi,
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.
Justin.

Subject: [Veritas-bu] Redhat Linux Media Server and MSDP Filesystem >16TB?
Hello.
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?
