RE: jls shows dead jails too?
Hi, I mentioned this bug a few months ago, and it is listed in the open bug reports, here: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/89528 But except that, jails run like a charm. I'm running a production server with about 15 jails for the moment, and no problem. Cheers, Philippe Lang -Message d'origine- De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] De la part de Marc G.

See my reply. Other things that I have seen are if you have a FS mounted inside your jail and that did not umount completely or appropriately, for example. For example, I use file backed md devices as jail file systems and I mount various pieces of a master jail inside my jail. If I do not umount everything cleanly before shutting the jail down it remains listed in the jls list Chad --- Chad Leigh -- Shire.Net LLC Your Web App and Email hosting provider chad at shire.net ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Either a process in the jail is still running, or it leaked resources while it was running (e.g. ptys - this is a known bug on everything prior to 7.0).

jls shows dead jails too?
I'm setting up a few jails on my FreeBSD 6.0 box and when I run jls to list my jails it shows all my started jails. The problem is that when I kill a jail with kill -TERM -1, thats what the man page tells me to use, it still is listed when I run jls. Why is that and is there any way to clear the jls list? Where does jls get the list of the jails?
