What is the maximum volume size for NFS and SwapFS?

Question

File systems

As well as the maximum file size and are they journaled?

Answer 1

NFS is a network transport, it doesn't care about journaling or the size of the FS underneath.

Answer 2

something like this
https://www.kernel.org/doc/gorman/html/understand/...
Bits 8-31 are used are to store the offset within the swap_map from the swp_entry_t. On the x86, this means 24 bits are available, “ limiting” the size of the swap area to 64GiB .
for NFS, the concept of "volume", "partition" is physically absent, it works with files.
each file can be up to 2^64 bytes ~~ 16 exabytes (16 million terabytes) in size.
