I'm having an issue where glusterfs is reporting the incorrect size for
recently changed files.
Can you check if the results are different after disabling md-cache?
md-cache can be disabled by running:
volume set <volname> stat-prefetch off
With stat-prefetch off I get the opposite problem. The file sizes are
correct, but the file contents are wrong.
However, with stat-prefetch off and using separate data and lock files,
where I make sure the data file is closed before releasing the lock, and
open the data file only after acquiring the lock, things work correctly.
Should I expect contents of a file to always be consistent across
clients after an fsync, or is an open on the client required to refresh
the data cache?
Note that with stat-prefetch on, I get the file size errors even when
using separate data and lock files.
Thanks
