https://bugzilla.kernel.org/show_bug.cgi?id=75621 Bug ID: 75621 Summary: Permission denied trying to touch a file; happens randomly; both ext3 and GPFS Product: File System Version: 2.5 Kernel Version: 3.0.13-0.27 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: ext3 Assignee: fs_ext3@xxxxxxxxxxxxxxxxxxxx Reporter: phillip.l.viana@xxxxxxxxx Regression: No Hi, I am running a benchmark against DB2 in my cluster with several ext3 (SSD) and GPFS file systems. After running the benchmark for around two days I noticed that one of the nodes rebooted and that was due to an error touching a file. The file was being touched by one of the HA monitors of Tivoli System Automation. I immediately tried to reproduce the error by touching the file again manually. I touched the file a few times successfully, then out of the blue I got a "Permission denied" error. Right after that I kept touching the file and got no error message. CPU utilization and I/O utilization were NOT at their peaks. This error keeps happening randomly and therefore it is difficult to reproduce. It has happened both on a GPFS file system and an ext3 file system. Also I don't have much information on the internals of this problem. Do you have suggestions on how to instrument/debug/monitor the error so that I can move on with the investigation and bring more info to this bug report?
