Hi,
I noticed that by copying a large file via client on a mounted nfs disk, on the nfs server, during the copy, a warning returns (see below).
The client freezes and returns this error in the journal: "NFSV4: State Recovery Failed for Open file ISO/.uruk -Cinnamon_3.0.iso, Error = -116"
The kernel installed on the nfs server is: "6.4.15-2-liquorix-amd64 #1 ZEN SMP PREEMPT liquorix 6.4-20.1~bookworm (2023-09-07) x86_64", on a Debian/Bookworm installation.
I used RSYNC to align: local disk directory -> remote directory on nfs server, locally mounted in nfs.
Thank you,
Antonio

I don't know if this is related, but NFS has had a long standing issue of not supporting modern Linux file data completely, leading to failures in unpredictable ways when using rsync.

i actually stopped doing network NFS / rsync backups because of this issue. There's some file system features in newer file systems that nfs does not know about.

Not sure if this is your issue or not, but it's worth mentioning.

I believe rsync over ssh does not have this issue, because it's an NFS issue, not an rsync issue.

Try doing the same rsync action over ssh and see if you get the same results, that might be useful information.

I released a v6.5 kernel (6.5.3 specifically), yesterday, can you give it a try?
