Rgds, Patrick clearly gets farther, but still no luck starting the jails. apparently, something's changed in the process of devfs creation/mount now that i'm using ZFS? or, have i missed an obvious step? do i perhaps need to set /j/jTEST as a separate ZFS mountpoint? e.g., zfs create z/j/jTEST zfs set mountpoint=/j/jTEST z/j/jTEST ? any suggestions ? thanks! ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: jail on ZFS - Unable to mount devfs
hi patrick, If I remember correctly there was no password file for in the jail. I think you have to rerun a certain command. Of course I do not remember the command :( The command should create the master password database. using the ServiceJail model, after populating the jail skeleton and running mergemaster, the two commands i run are, /usr/bin/cap_mkdb /j/jSKEL/etc/login.conf /usr/sbin/pwd_mkdb -d /j/jSKEL/etc -p /j/j/etc/master.passwd which should take care of that. Also you have to run within in the jail newaliases to create the aliases file, do a touch /etc/fstab to stop complaints about unable to read mountpoints. hm. i did not do that this time around. i'd built my jail-world with *both* NO_MAILWRAPPER=true NO_SENDMAIL=true, so i mayhave caused myself a problem. rather than cp'ing bins, tobe safe, i'll just rebuild world ... and see in a bit if that helps. thanks. Furthermore I am not sure that you can run a jail on a zfs file system. The setup I have is that I run my jails on ufs and have a zfs filesystem available within the jail. ?? if that's true, then that renders the rest moot -- and i have a problem. atm, i have cat /etc/fstab /dev/mirror/gm0s1a /bootdirufs rw1 1 /dev/mirror/gm0s1b noneswapsw0 0 /dev/acd0 /cdrom cd9660 ro,noauto 0 0 /j/jMROOT /j/jTESTnullfs ro0 0 /j/s/jTEST /j/jTEST/s nullfs rw0 0 zfs list NAME USED AVAIL REFER MOUNTPOINT z5.23G 213G 250M /z z/data 20K 213G20K /data z/home 28.5K 213G 28.5K /home z/j23K 213G23K /j z/tmp 406K 213G 406K /tmp z/usr4.88G 213G 4.88G /usr z/var 105M 213G 105M /var where z/j is a zfs mount. i *can* access the jail, and do just about 'all' i need to in the jail (builds, exec, etc). but do *not* yet know if, by running the jail on zfs space whehter i've compromised anything. do you have a reference for your comment? or, perhaps, someone else can comment, as well? thanks! ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

RE: jail on ZFS - Unable to mount devfs
not surprising, as step (4) @ .../handbook/jails-application.html had me rm -R bin boot lib libexec mnt proc rescue sbin sys usr dev -- From jails-application.html -- cd /home/j/skel # rm -R bin boot lib libexec mnt proc rescue sbin sys usr dev -- The root is in /home/j/mroot and nullfs mounted read only to the jail root So if you ran the rm in /j/jTest you did not follow the directions any suggestions ? Dont do jail-appliations ... use a full world onside the jail Here's a short draft from my playing around with ZFS and 7.0-RC1 http://gugge.dlx.dk/bsd/zfs-jail Notice that I don't use the normal way of buildworld/installworld to populate the jail. I just unpack the distfiles from the CD. But a make installworld DESTDIR=/jailpath would do just fine too -- Karsten ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
