I emailed samba upstream, via the mailing list[1], and the consensus seems to be "don't do this": re-exporting a network mounted filesystem/share is asking for trouble, specially when using different protocols. File locking by itself will be a mess.
A better solution would be to export the storage via smb from the source, multiple times: storage -> NFS, storage -> SMB. Instead of storage -> NFS -> SMB. Granted, we still don't know why it works when debian is the nfs client and the smb server. If someone can point us at the exact cause, then perhaps a fix could be envisioned. But for now, this bug has taken many hours of troubleshooting already, and I fear there isn't much more we can do. 1. https://lists.samba.org/archive/samba/2025-May/251555.html -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2077725 Title: CIFS client reports 100% disk usage when rpc-quotad is started To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/2077725/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
