Hi, all,

Since upgrading to Fedora 33, I am having some problems accessing files on NFS shares. I should say first that, immediately after the upgrade, the shares would not mount at all. I was getting the error:

mount.nfs4: Operation not permitted when mounting NFS device

even when attempting to mount manually. Eventually, I found some info online that suggested mounting manually as root, which created some symlink or other. After that, the shares would mount automatically at boot.

However, now, as I said, I have problems accessing files on said shares. The directory ~/files/ is an NFS mount from a server running CentOS 7. My LyX user directory is at ~/files/config/lyx/ (symlinked from ~/.lyx/). LyX refuses to start, blocking at a call to
lockf(fd, F_LOCK, 0) at support/filetools.cpp, during startup. (I believe that fd here points at a file on the NFS share.) I can successfully start LyX via:

    lyx -userdir ~/tmp/lyx

say. I can then restart LyX with the same command and all is well. I can also start it with

    lyx -userdir ~/files/lyxnew/

where that is a *non-existent* directory on the NFS share. In that case, LyX goes through its configuration process and starts normally. However, if I then attempt to run that same command again, LyX does not start. Also, if ~/files/lyxnew/ does exist, then LyX will not start, even if it is empty.

I am seeing a similar problem with Libre Office. I can starti fine, but if I then attempt to open a file from ~/files/, Libre Office freezes. It does not matter when it is ODT or ODS, say. I have not seen the problem in other programs, but I only upgraded yesterday.

I am guessing that there is something wrong with the NFS configuration. But I did not change anything myself.
