From: Marc Dionne <marc.dionne@auristor.com>
By default s_maxbytes is set to MAX_NON_LFS, which limits the usable file size to 2GB, enforced by the vfs.
Commit b9b1f8d5930a ("AFS: write support fixes") added support for the 64-bit fetch and store server operations, but did not change this value. As a result, attempts to write past the 2G mark result in EFBIG errors:
$ dd if=/dev/zero of=foo bs=1M count=1 seek=2048 dd: error writing 'foo': File too large
Set s_maxbytes to MAX_LFS_FILESIZE.
