But haven't seen it since release versions. In my case top shows depmod and weak-modules; and many small files being created and destroyed in a loop. [1] But haven't seen it in a while or with any of the 5.10 or 5.11 kernels. If you aren't seeing those indications: Do you have any 3rd party modules that depend on dkms? Are you running a 5.10 series kernel at the time, and is sysroot btrfs? [2] [1] Install fatrace and run it with sudo. It works on any file system but it doesn't show file sizes, just path to file. A btrfs specific way of find this info, with inode, size, and path: First get the current generation value for the subvolume you want to find recent files. # btrfs sub list -t / ID gen top level path -- --- --------- ---- 258 1574871 5 home 339 1568566 5 boot 429 1574871 5 root It's 1574871. This increments with each transaction, and a transaction is 30 seconds unless some process does fsync (which I don't think the kernel install uses until the very end). Next... # btrfs sub find / 1574870 Note it's one value less, as an example. And you'll get a bunch of lines representing files that have been created or modified since the specified generation value. The current generation is incrementing as time goes on so you can bump up the value of the generation you specify to keep the output short, and thus recent. -- Chris Murphy _______________________________________________ test mailing list -- test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to test-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@xxxxxxxxxxxxxxxxxxxxxxx
