We have been using a NFS-mounted Synology NAS drive for data processing in cryoSPARC on one of our GPU workstations, which has worked very well. However, cryoSPARC on a different workstation in the lab claims the NAS is unwritable and will neither create a project on it nor attach a pre-existing project, even though both operations worked immediately on the same NAS from our other workstation. Both workstations are running NFS 4.1, although the one on which cryoSPARC works properly with the NAS is running CentOS7, while the one that doesn’t work is running Ubuntu 18.04. The permission for both are set the same on the NAS and look the same when listed from the command line on both workstations. Here’s output from the workstation on which cryoSPARC claims the NAS is unwritable:
$ echo "testing" >/mnt/nfs_SynologyCryoEM/data/cS/test.txt
$ cat /mnt/nfs_SynologyCryoEM/data/cS/test.txt
testing
$ ls -lah /mnt/nfs_SynologyCryoEM/data

Any insight or recommendations about additional diagnostics would be tremendously appreciated. Both workstations are running cryoSPARC 4.4.1.
