Creating MSDP on RedHat 6

 

We are currently working on setting up some Media Storage servers in out new NetBackup environment. Currently, in 7.1.0.3, the MSDP pools can be up to 32tb in size. With 7.5, that grows to 64tb in size. When looking at setting up the storage for our MSDP pools,our RedHat admin is trying to create a file system where the pools will reside. He keeps seeing that the EXT4 file system has a max file size of 16tb. I see that XFS file system can go up to 8 exabytes. What file system do we need to setup for our MSDP pools, or do we just need to setup a raw partition? Hopefully this all makes sense.

7.1.x and Earlier
Backing Up
Backup and Recovery
Best Practice
Configuring
Deduplication Option
Installing
NetBackup

    Normally, most files are stored in 256MB containers, so the 16TB file size is not relevant, unless EXT4 is limited to indeed 16TB file system size.

    However, if you intend to use the full 32-64TB size of a MSDP, you are probably better off using VxFS or XFS anyways... EXT4 has a lot of features, but in my experience, XFS and VxFS has proved to work quite well.

    As the above thread says use VxFS or XFS (it would generally be XFS is you have not purchased VxFS)

    RAW is not an option

    Dont forget to plan carefully your storage to put the MSDP database on its own spindles and also bear in mind that the new 64TB limit requires more memory and CPU so ensure your server is up to it

    Thanks for the quick response. We will look into using XFS. Also, I understand that Symantec uses Storage Foundation on their appliances. That's how they get aroung the 16tb limit. We will look into that as well. Thanks.
