Indeed, the sizes of the /var/lib/rpm directory are quite big, "du -hs /var/lib/rpm" from various Fedoras or RHELs: 216M /var/lib/rpm 182M /var/lib/rpm 273M /var/lib/rpm 277M /var/lib/rpm 223M /var/lib/rpm 41M /var/lib/rpm So I would be also against collecting that by default (I think this is consensus here) and mildly against collecting it after timeouted plugin. Also with the big size of /var/lib/rpm, I tend to agree with Jake and not collect the directory content after plugin timeout. So we can currently offer: - decreasing rpm plugin timeout to e.g. 1 minute (as the commands are usually very quick and can exceed this timeout only in case of a lock - which prevent commands execution also on the default 5m plugin timeout - so the timeout decrease can speed up things in case of locking problems - add a plugin option - disabled by default - to grab whole directory content without a size limit Or do I miss some idea or option?

Hello, please let us know your preferences (or suggest another idea). The reality today is that if a sosreport doesn't have an operable RPM database, the Support Delivery teams ask for the /var/lib/rpm directory. The raised concern around the size of the directory is valid, and indicates to me that we should not pursue just a blanket gathering of the contents. That being said, the request here is to get the teams the data they need on the initial capture when that invalid state is encountered. I don't see how having a timeout-bound fallback behaviour of gathering the /var/lib/rpm directory is anything less than perfect for this purpose. Issue migration from Bugzilla to Jira is in process at this time. This will be the last message in Jira copied from the Bugzilla bug. This BZ has been automatically migrated to the issues.redhat.com Red Hat Issue Tracker. All future work related to this report will be managed there. Due to differences in account names between systems, some fields were not replicated. Be sure to add yourself to Jira issue's "Watchers" field to continue receiving updates and add others to the "Need Info From" field to continue requesting information. To find the migrated issue, look in the "Links" section for a direct link to the new issue location. The issue key will have an icon of 2 footprints next to it, and begin with "RHEL-" followed by an integer. You can also find this issue by visiting https://issues.redhat.com/issues/?jql= and searching the "Bugzilla Bug" field for this BZ's number, e.g. a search like: "Bugzilla Bug" = 1234567 In the event you have trouble locating or viewing this issue, you can file an issue by sending mail to rh-issues. |
Requesting some updates with sos. Currently we have a plugin (rpm.rpmdb) which is off by default and only copies all of /var/lib/rpm into the sosreport. My suggestions for improvement are: 1. When rpm/yum plugin fails or timeout's, automatically grab the rpm database 1b. Decrease the timeout for rpm/yum plugins failing 2. The rpmdb plugin should first attempt to tar the entire database for a more usable format for engineers RHEL 7 and lower # tar cjf rpm_db-$(hostname).tar.bz2 /var/lib/{rpm,yum} RHEL 8 and higher # tar cJhf rpm_db-$(hostname).tar.xz /var/lib/{rpm,dnf} /etc/{dnf*,os-release} - - - - - - - - - If there is any concern over size I would secondarily request we make this generate the tar outside of the sos Example: sosreport > detects rpm issues > generates /var/tmp/rpmdb.tar.xz Or just have it inside the rpm database.
