Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Description of problem:
When the file is created, the atime is lower than ctime or mtime. When the file is accessed using cat, the atime does not get updated.
Also the option strictatime is not effective (the atime updates the same way as with standard relatime).
This issue was found with the help of xfstests (test no. 192).
Version-Release number of selected component (if applicable):
kernel-2.6.32-119.el6
How reproducible:
Fairly often but not 100 %, don't forget to remove file that you are going to test the atime with and wait for a while before the test.
Steps to Reproduce:
1. mount nfs share (I used localhost nfs server)
2. cd to the mounted share
3. echo test >file;stat file;sleep 40;cat file;stat file
Actual results:
atime is lowest of the three at first stat and remains that way even after the cat.
Expected results:
The access time is updated after the cat.
