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.

Fixed In Version: logrotate-3.7.8-17.el6
Doc Type: Bug Fix
Doc Text:
Cause: Logrotate always tried to set owner of the rotated log even when the owner was the same as the current owner of the log file. Consequence: On filesystems (or systems) where changing the ownership was not supported, the rotation failed. Fix: Before the ownership is changed, Logrotate checks if it is real change of ownership (it means if the new ownership is not the same as the previous one) and skip the change if it isn't real ownership change. Result: Logrotate rotates logs properly on mentioned filesystems (systems).

Description Ondrej Valousek 2012-07-19 09:41:06 UTC 
Description of problem:
logrotate seems to be unable to compress files on NFSv4 volume.
logrotate -vvv says:
...
compressing log with: /bin/gzip
....

but eventually, logs are not zipped.
Is anyone able to reproduce this?
Comment 2 Ondrej Valousek 2012-07-19 10:03:19 UTC 
also note that same settings work fine on RHEL 5.8
Comment 3 Jan Kaluža 2012-07-19 10:11:44 UTC 
Could you please attach logrotate configuration file for which it's broken? And also full output of "logrotate -vf /etc/logrotate.d/config.cfg" would be helpful.

Comment 5 Jan Kaluža 2012-07-19 18:55:39 UTC 
By "/etc/logrotate.d/config.cfg" I meant config used to reproduce this error, so in your case it's: "logrotate -vf /etc/logrotate.d/sge". Could you please run it and paste the output here?

Comment 7 Jan Kaluža 2012-07-20 11:10:00 UTC 
Thank you very much. I'm able to reproduce it and will attach patch to fix this issue here soon. However, it shows the same error for me even with logrotate in rhel-5.8.

error: error setting owner of /proj/sge/default/common/reporting.1.gz: Invalid argument
Comment 8 Ondrej Valousek 2012-07-20 12:40:20 UTC 
Ok, for me it worked with RHEL 5.8 (using NFSv3 - did not test v4 though).
Will the fix find its way into U4 please?
Thanks
Comment 9 Jan Kaluža 2012-07-23 07:58:48 UTC 
I think it's caused by different NFS settings. The problem is that logrotate tries to change the owner of "reporting.1.gz" according to original "reporting" log file. This behaviour is in logrotate in RHEL6 and also in RHEL5. But on your NFSv4 configuration, it's not able to change the owner so it fails to rotate that particular log.

It's the same like when you run for example "chmod nobody:nobody /proj/sge/default/common/reporting". That command will fail for your NFS too probably.

Patch I will attach right after this message fixes this behaviour. With this patch, logrotate checks the "reporting.1.gz" owner and if it's right, it won't even try to change it. This fixed the bug for me.
