Subject: bug#27666: [grep on GPFS filesystem] SEEK_HOLE problem

Hi,

I use GPFS file system and I have sometimes an issue using grep command.
When issue occurs with the following message "Binary file <myfile> matches"
But "<myfile>" is an ASCII one, not a binary file.
The problem seems to deals with lseek(SEEK_HOLE) command and a file not completely flushed after close.
It could take several seconds to save the entire file on the disk.

So could grep command have another way to determine if input file is binary/ASCII instead using lseek(SEEK_HOLE) ?

Best regards
john
