FreeBSD 9-R pxeboot fails with 'Mounting root filesystem rw failed'...
Hi, I've got a 9.0-R amd64 system I'm trying to netboot / pxeboot from the network, to install other machines (and do fixups etc.) I set this up as we setup previous versions here - but setting up a tftp server, and nfs server - and 'dumping' the contents of the install CD to a directory on the dhcp server, which is exported via nfs (it's exported as read/write). The system kind of boots, but falls over with: Interface em0 IP-Address 192.168.0.47 Broadcast 192.168.0.255 Entropy harvesting: interrupts ethernet point_to_pick kickstart. Starting file system checks: mount_nfs: no host:dirpath nfs-name Mounting root filesystem rw failed, startup aborted ERROR: ABORTING BOOT (sending SIGTERM to parent)! Mar 1 118:10 init: /bin/sh on /etc/rc terminated abnormally, going to single user mode Enter full pathname of shell or RETURN for /bin/sh: It looks like it's failing to 'remount' / promote the root file system as read/write (It's definitely exported as read/write - I've tested it by mounting it on another machine). If you start a shell at this point and run mount, you get: 192.168.0.37:/usr2/netboot/os/9.0-amd64 on / (nfs, read-only) devfs on /dev (devfs, local, multilabel) Is there something I have to set (e.g. in '/etc/rc.conf') in order to fix this? Previous systems setup this way would always boot through to the sysinstall menu.

Re: FreeBSD 9-R pxeboot fails with 'Mounting root filesystem rw failed'...
Take a look at freebsd-hackers mailing list... I have suggested some change in some Makefile and sh script in order to unless at this moment to be able to have an unattended system built with sysinstall (the idea I think it was to maintain sysinstall in 9.0 unless) and using you're install.cfg At freebsd-hackers seems that people is pretty busy and can't look at this in order for committing or unless saying something about it... perhaps they're working on another thing or so, or don't know I assume they can't check this now... but like changes are not significant... I am going to do with the changes suggested and have tested and release builts fine and you can use Jumpstart without issues.. this way... So I recomend you reading last mails of mine in freebsd-hackers... Hope it helps, Bye!

For what it's worth - I've resolved the issue I had (which was basically the system booted, but failed trying to re-mount root as RW, and hence wouldn't go into the installer). The fix I did was to change the '/etc/fstab' on the Netboot server (i.e. the copy of FreeBSD that you're booting). It contains: /dev/iso9660/FREEBSD_INSTALL / cd9660 ro 0 0 Just commenting out that line, i.e. #/dev/iso9660/FREEBSD_INSTALL / cd9660 ro 0 0 Means the boot now completes, and I get offered the Install / Shell / Live CD prompt, instead of an error about not being able to remount root. I've yet to complete an install this way (so far we're just using a script to extract the new 9.x style '.txz' files). But that little change does let us netboot correctly now, enough for what we need. -Karl ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: FreeBSD 9-R pxeboot fails with 'Mounting root filesystem rw failed'...
In the new way of booting... you need to have the cd because the own cd is the root filesystem... and in fact is live filesystem too so unless you're booting from mfsroot... I assume you should have that line in /etc/fstab inside the iso image but if you're using mfsroot... I really even am not creating etc dir inside the iso image... because it's not needed and in previous releases and iso images when always booted from mfsroot (and where not livefs cds and so) it wasn't necessary...
