Hi all,
I've a 30TB hardware based RAID array.
Wondering what you all thought of using ext4 over XFS.
I've been a big XFS fan for years as I'm an Irix transplant but would like your opinions.
This 30TB drive will be an NFS exported asset for my users housing home dirs and other frequently accessed files.
You will need XFS for a single partition that large. You won't be able to make such a large ext4 partition, I don't think.
This is correct. While ext4 theoretically supports volumes (much) larger than 16TB, the developers don't think it's production ready yet and the userspace tools don't support it yet.
So, short answer -- XFS is the only way to go.
My RAID has a strip size of of 32KB and a block size of 512bytes.
I've usually just done blind XFS formats but would like to tune it for smaller files. Of course big/small is relative but in my env, small means sub 300MB or so.
What would your XFS tuning params be for such an env?
