This worked. For my example I will let the guest start on tty8 and spawn gettys on tty8 and tty9. Steps: - create /dev/tty8 (major 4, minor 8) - create /dev/tty9 (major 4, minor 9) - create /dev/console (major 4, minor 8) - add "c8:2345:respawn:sbin/getty 38400 tty8 linux" to inittab - add "c9:2345:respawn:sbin/getty 38400 tty9 linux" to inittab Then start/restart the guest and output appears as expected. Guest is configured using init style "plain" Bruno ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver

Re: [Vserver] mountpoint blocked even with all context shutdown
Hi Herbert, Hi Christian, you have to start 'thinking' in namespaces and avoid leftovers and unwanted 'copies' or duplicate mounts ... I do !! But as mentioned in my OP 1) The mount is done inside the namespace of the guest - it is not visible outside in the root and is not copied into later started servers. At least I can confirm this with issuing "mount" inside the guest (vserver www1 enter and then >mount) inside the namespace (vnamespace -e www1 mount) Neither one shows the mount ! 2) I shutdown ALL virtual servers, so I assume that all namespaces are destroyed. At least vserver-stat does not show anything beside the root server and "vps ax" does not show any process running with another ID than "main"... So, I see two possible approaches on the probleme: 1) drbd keeps its own "mount" table that is not freed correctly 2) the kernel blocks mounts from a not longer active namespace I dont have any idea how to debug, and to make it even harder, the problem shows not on all mounts/guest, which are basically configured all identical. It might be a problem that the mount inside the namespavce is not cleanly freed when the startup/shutdown of the guest fails/hangs somewhere, but this is only a wild guess :( Oliver -- Diese Nachricht wurde digital unterschrieben oliwel's public key: http://www.oliwel.de/oliwel.crt Basiszertifikat: http://www.ldv.ei.tum.de/page72 smime.p7s Description: S/MIME Cryptographic Signature ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver

Re: [Vserver] mountpoint blocked even with all context shutdown
Hi Grzegorz It might be a problem that the mount inside the namespavce is not cleanly freed when the startup/shutdown of the guest fails/hangs somewhere, but this is only a wild guess :( If you stop your guest in an unclean way (e.g. vwait times out), the namespace stays there (or at least it used to be when I was playing with them). You can clear it with vnamespace -c but do check the syntax so that you don't wipe your root namespace :) vnamespace --help --cleanup|-c ... remove all mounts from the namespace of the current context So it does not take a XID as arguement... vnamespace -e with statically asigend xid of the formerly used namespace die's with "vnamespace: vc_enter_namespace(): No such process" Any other ideas ? Is there a way to list namespaces known to the kernel and "kill" them ?

Hi Herbert, Hi Christian, you have to start 'thinking' in namespaces and avoid leftovers and unwanted 'copies' or duplicate mounts ... I do !! But as mentioned in my OP 1) The mount is done inside the namespace of the guest - it is not visible outside in the root and is not copied into later started servers. At least I can confirm this with issuing "mount" inside the guest (vserver www1 enter and then >mount) inside the namespace (vnamespace -e www1 mount) Neither one shows the mount ! 2) I shutdown ALL virtual servers, so I assume that all namespaces are destroyed.
