Error nfs_grace
The server is still starting up
The NFSv4 server just restarted and is in its grace period (typically 90 seconds) while old clients reclaim their state. Wait a minute and retry.
What this means
NFSv4 status 10013, GRACE. After a restart, an NFSv4 server refuses new operations for a grace period so clients that were mid-write can recover. NFS Files has nothing to recover, but it still has to wait.
Fix
Wait 60–90 seconds and try again. On Linux the period is /proc/fs/nfsd/nfsv4gracetime (default 90 s); on a NAS it isn’t adjustable. If the server always reports grace, its NFS service is crash-looping — check the NAS log.
