Since today's topic seems to be Lustre striping, I will revisit a
previous line of questions I had.
Andreas had put me on to O_LOV_DELAY_CREATE which I have been
experimenting with. My question is : Is there a way to flag a directory
with O_LOV_DELAY_CREATE so that a file created in that directory will be
created with O_LOV_DELAY_CREATE also. Much like a file can inherit a
directory's stripe count and stripe size, it would be convenient if a
file could also inherit O_LOV_DELAY_CREATE? That way, for open()s that
I can not intercept ( and thus can not set O_LOV_DELAY_CREATE in oflags)
, such as those issued by fopen(), I can then get the fd with fileno()
and set the striping withioctl(fd, LL_IOC_LOV_SETSTRIPE, lum).
Thanks
John
