Re: [PLUG] XFS limits


It turns out that the very next file bumps the total size above 4
TB. Regardless of the cause, it's clear that the limit exists for me.

Which is fine. I already knew going in that I was going to have to
transfer the files in multiple batches. Whether I split at 4 TB or 5
TB doesn't matter. I made a small tweak to my script to generate
directories of symlinks, and I'm good to go.
