Re: [NFS] blocks of zeros (NULLs) in NFS files in kernels >= 2.6.20

Hi,

Why can't you use O_SYNC | O_APPEND ?

In our case, some of the writers are not in our control. Another case
we see the issue is you spawn a job:

job 1> out 2> err &
tail -f out err

--

Also, we actually do like caching the writes (b/c log files do not need
to be checked immediately after being written). We just wish the cache
could be written out in-order.

If there's no way to make that happen... we can reorganize our
file-system, exports, mounts, etc so that the log file directory is
mounted with the sync option.

However, the problem *might* be annoying and wide-spread enough to
warrant a change.

Anyway, thanks!

Regards,
