It *is* Easter weekend.
I have a f24 workstation (nfs client). It is updated regularly.
The server is f19, so no updates there.
A problem started in the last few weeks. When I examine a file on the
server it looks OK. The file is updated every minute (collecting some
stats) and 'tail' shows the added lines as they arrive.
Examining the same file from the workstation is initially OK, but
then, as the file grows, I get binary zeroes at the end of the file.
The same with tail, less, vi, etc. The amount of zeroes seems to be
the size of the extra data appended to the file. 'ls' shows the
actual (full) size of the file. It looks like the utilities see the
correct size but bad data is delivered at the tail.
After a few minutes the full data is showing but then, as the file
grows, again I get zeroes for a few minutes.
Where do I look next?
I don't know nfs, but this sounds like a buffering issue. On the
server, the update occurs immediately, so you see the data. On your
workstation, nfs knows an update has occurred by the size, but hasn't
sent the data yet, waiting for enough to accumulate, so it displays it
as zeros. Just a wild guess that seems to fit your experience.
