Description Diane Feddema 2014-07-30 14:29:21 UTC
Description of problem:
We experienced very infrequent FNF errors (3 occurrences in one month period) when running hadoop benchmarks: Wordcount, TestDFSIO read and Pi Estimator, on glusterfs.  During the time period when the errors occurred we had a disk fail in our RAID6 array which the gluster volume resides on. Since we replaced the downed disk we have not been able to reproduce this problem.

Note about the comment about disk replacement - the actual 'no such file or directory' (or 'File not Found' in Java lingo) seems not to be caused by the disk failure/replacement, but probably just impacted probability with timing/races because of delays.

Comment 5 Anand Avati 2014-08-07 17:59:09 UTC
A correction: 'File not Found' is a generic exception Java throws. It was found during debugging that the system errno was ESTALE and not ENOENT (Java just throws FNF exception even for ESTALE). Hopefully that clarifies the intention of the patch.
