Description Shing-Shong Shei 2006-11-17 11:31:42 EST
Description of problem: ACL works intermittently via NFS

Version-Release number of selected component (if applicable):

How reproducible: Not sure -- don't know how it failed and how it started
working again.  Two scripts enclosed.

Steps to Reproduce:
Actual results:

Expected results:

Additional info:

We have a RHEL 4.4 NFS file server and when users try to use ACL on the
client machines, sometimes it works but sometimes it failed.  We don't
have a way to reproduce it reliably yet.  Luckily we caught two instances
using strace that shows a successful one and a failed one.

Anybody home?  Has this case been taken?
Thanks.  --Bruce

In both cases strace output is exactly the same until the first getxattr syscall, which returns ENODATA. This means it can't be a bug of getfacl. It might be caused by NFS or more likely the remote server.

Any chance the remote file could be alternated between the tests?

> Any chance the remote file could be alternated between the tests?

Wow three years later, finally somebody starts to look into this issue.  Frankly speaking, it's been so long that I cannot even recall the details.  But if you want an answer, I'd say that the remote file has not been changed for sure as during the test, no reason for me to change it, especially when I tried to make a case.  Anyway, we have since moved to RHEL 5 and have not seen this error.  So we can close this case now.  Thanks for looking into it.  Have a Happy Holidays.

Sorry for the delay. Don't blame me as I got the ACL package three hours ago :-) Thanks for the additional info. I am closing the bug as NEXTRELEASE.
