I don't believe there are very man anonymous pages, but there are lots of named pages. If those are dirty, does that mean they have not yet been written back to disk? The loss of those would be quite detrimental if not written back to disk. -- Doug ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

Laundry
I have a production system (12.1-RELEASE-p6) that is showing around 1 GB of Laundry pages. There are over 6 Gb Inact and 1 Gb free. I can understand why the system would want to not prioritize laundering those pages as there is plenty of available pages. However, does that mean that I have about 1 GB of updated files that have not been written back to disk? If so, then there is a significant issue with power failures and loss of data. -- Doug ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
VM laundry size is always 0
Hello! I’ve got strange values for vm laundry size on -STABLE. And these values do not change even under load. vm.domain.0.stats.laundry: 0 vm.stats.vm.v_laundry_count: 0 I cannot complete buildworld on this box, compiler throughs segmentation core at some random points. I tested RAM and hard disk for errors - none found. Has anyone seen this?
