To me it looks like a case of a flush triggering a write() that was cached by write-behind and because the write buffer

did not meet the page alignment requirement with o-direct write, it was failed with EINVAL and the trigger fop - i.e., flush() was failed with the 'Invalid argument' error code.


Could you attach the brick logs as well, so that we can confirm the theory?

Pranith/Krutika,


Your inputs please, IIRC we'd need to turn on some o_direct option here?

The errors also occured in GlusterFS 3.6.7，I just add the O_DIRECT flag in client protocol open() and create()! How to explain and solve the problem?

Any specific reason of using 3.3 given that its really quite old? We are at 3.6, 3.7 & 3.8 supportability matrix now.

hi,
    I have installed GlusterFS 3.3.0, and now I get Fsync failures when saving files with the O_DIRECT flag in open() and create().
    1, I tried to save a flie in vi and got this error:
        "test" E667: Fsync failed
    2, I see this in the logs:
