And i have tested 2.4.16 and 2.4.18. Both of these two version have the same problem when system reboot. "/: device is busy"; in shutdown script: umount -a mount -n -o ro,remount / these two line result error: device is busy. I switch to init 1, and all user process go away. except the following: root 1 0.1 0.7 1056 484 ? S 15:46 0:04 init [S] root 2 0.0 0.0 0 0 ? SW 15:46 0:00 [keventd] root 3 0.0 0.0 0 0 ?

How can i resolve this problem? Regards; Michael ^ permalink raw reply [flat|nested] 7+ messages in thread

It clearly appears to be a user problem. Order of operations, as I read in the original email: 1) "/" and "/usr" are busy 2) shut down to single user mode 3) "/" still busy 4) "/usr" can be unmounted 5) didn't check that root can be remounted after umounting "/usr" Clearly, some program is keeping "/usr" busy (which is keeping "/" busy) before the change to single user mode. Just a bit of "lsof" needed to find such things.
