My method for causing the problem every time (example works under 2.6.9-ck3 and 2.6.10-rc2-bk7) # mount tmpfs tmp/ -t tmpfs # TMPDIR=./tmp/ /kernels/non-fix-kill-patched-kernel rootfs=debian.fs # uml_mconsole .uml/xxx/mconsole cad # kill -KILL # umount tmp/ umount: /root/tmp: device is busy (cad is set to shutdown in the UML's inittab. After sending CAD, it hangs, which requires kill) Under 2.6.10-rc3-bk10 this works fine --the tmpfs mount is unmounted without problems. Perhaps it's fixed in recent patches. :) -Chris ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

When all UMLs are gone "lsof|grep deleted" returns nothing,=20 but "df /tmp" still shows the allocations. In this situation attempts=20 to umount (or remount ro) the /tmp fail, even in single user mode. The only way to recover from such a /tmp full situation is to reboot=20 the host (then unmount of /tmp and the rootfs fail during shutdown,=20 which causes fscks at the reboot...) I tried out different filesystem types for /tmp: reiserfs 3.6, ext3=20 and tmpfs, no difference. Anybody seen such behaviour before? I suppose this must be a bug of the _host_ kernel, not of the UML=20 kernel. Do you agree? Armin. =2D-=20 --- May the Source be with you!
