Hi, We have a GPFS filesystem mounted on CentOS 7.4 as type gpfs, pretty straightforward run of the mill stuff. But are seeing this odd behavior. If I do this in a shell script, given a file called "a"
cat a a a a a a a a a a > /path/to/gpfs/mount/test grep ATAG /path/to/gpfs/mount/test | wc -l sleep 4 grep ATAG /path/to/gpfs/mount/test | wc -l The first grep | wc -l returns 1, because grep outputs "Binary file /path/to/gpfs/mount/test matches" The second grep | wc -l returns the correct count of ATAG in the file. Why does it take 4 seconds (3 isn't enough) for that file to be properly recognized as a text file and/or why is it seen as a binary file in the first place since a is a plain text file? Note that I have the same filesystem mounted via NFS and over an NFS mount it works as expected. Any illumination is appreciated, jbh
