I was looking at https://gitlab.com/psmisc/psmisc/-/issues/39 which is a similar, but different issue. Same physical device but due to mount namespaces different device ID. I'd be curious if lsof finds the access.
Also the mountinfo-list finding it is curious, it matches devices a different way. - Craig On Tue, 22 Aug 2023 at 12:07, Paul Kimoto <kim...@fastmail.net> wrote: > On Wed, Aug 16, 2023 at 11:03:14PM -0400, Paul Kimoto wrote: > > On Wed, Aug 16, 2023 at 05:25:26PM +1000, Craig Small wrote: > >> What does > >> grep -e ' 0:2[57] ' /proc/self/mountinfo > >> show? > > > > 29 1 0:25 /@rootfs / rw,relatime shared:1 - btrfs /dev/sda3 > > rw,compress=zstd:1,ssd,space_cache=v2,subvolid=256,subvol=/@rootfs > > FWIW, fuser from psmisc-23.4 configured with > "--enable-mountinfo-list" produces the kind of output I expect. > (Without "--enable-mountinfo-list", it doesn't.) >
