It seems that in the passenger client threads it calls closeStream which
errors when
the socket close errors with ENOTCONN
virtual void closeStream() {
TRACE_POINT();
if (fd != -1) {
int ret = syscalls::close(fd);
fd = -1;
if (ret == -1) {
if (errno == EIO) {
throw SystemException(A write operation on the
session stream failed,
errno);
} else {
throw SystemException(Cannot close the session
stream,
errno);
}
}
}
}
This causes it to call abort on the the thread which then crashes the app
with
the above stack trace, which seems really weird. Anyone got any ideas?

I haven't tested that myself, but everywhere I look seems to indicate that booting off a simple stripe doesn't work or is that everywhere also out of date after your changes? :) It's probably unsupported in Solaris/OpenSolaris because of their bootloader. Our bootloader is completely different from theirs and so is not subject to those restrictions in the ZFS docs. The bottom line is that I think FreeBSD can boot from pretty much any configuration, except possibly from systems with huge numbers of disks.

On Thu, Feb 18, 2010 at 4:36 PM, Dan Naumov dan.nau...@gmail.com wrote: A stripe of 3-way mirrors, whoa. Out of curiosity, what is the system used for? I am not doubting that there exist some uses/workloads for a system that uses 6 disks with 2 disks worth of usable space, but that's a bit of an unusual configuration. What are your system/disc specs and what kind of performance are you seeing from the pool? It's for a reasonably busy webserver hosting a few hundred domains, which tends to be somewhat seek-intensive. For this pool we had two main criteria: speed and double-disk redundancy. A stripe of three two-way mirrors would only give us single-disk redundancy in the worst case (i.e. losing both disks in one of the mirrors), so we went with two three-way mirrors instead. Even though we're only getting the capacity of two disks worth of space, we'll still have 6x the capacity of the array it's replacing. A simple-minded dd test gives me ~180MB/s writing a single long file, and 400-500MB/s reading.

But what about booting off pools consisting of multiple striped mirror or raidz vdevs? Like this: Assume each disk looks like a half of a traditional ZFS mirror root configuration using GPT 1: freebsd-boot 2: freebsd-swap 3: freebsd-zfs |disk1+disk2| + |disk3+disk4| + |disk5+disk6| My logic tells me that while booting off any of the 6 disks, boot0 and boot1 stage should obviously work fine, but what about the boot2 stage? Can it properly handle booting off a root filesystem thats striped across 3 mirror vdevs or is booting off a single mirror vdev the best that one can do right now?

Re: ZFS on root, serial console install
On Thu, Feb 11, 2010 at 10:27 PM, Charles Sprickman sp...@bway.net wrote: Any hints on that one? I finally got around to getting dhcp/tftp/nfs setup on an internal network to perform normal installs (and with some pxelinux hackery, the ability to boot a DOS disk or memtest86 disk images). Sysinstall in general is kind of an unweildy beast over serial, but one thing I was not able to accomplish was to get a shell (no extra virtual consoles on serial) or attempt any mounting of fixit media. From my last install that put ZFS on root, I had to do quite a bit of tapdancing since I had no DVD or bootable USB media - lots of switching from the install disk to fixit, which brought me to many chicken and egg moments. I did it though... But remotely, I'm not seeing a good way to do this. If mfsroot were larger and had more tools, then I'd be in business. This is probably the direction I need to get shoved in. I've looked at some other options with pxelinux and perhaps booting the mini ISO, but I'm not sure that gets me anywhere. Any tips? This isn't a make or break situation, I live 15 minutes from the colo... It's more of a quest. :) The way I do it is to boot over the network using pxeboot, configure the partitions and ZFS pool and filesystems mounted on /mnt, then install using sysinstall, using the Options dialog to set the install directory to /mnt. I think I created the NFS filesystem using make installworld DESTDIR=/usr/nfs/freebsd or something like that; this gives you all the tools you need.

Today, when attempting to fire up this FreeBSD guest in VirtualBox I get this on the console: = ZFS: unsupported ZFS version 14 (should be 13) No ZFS pools located, can't boot _ = and the boot halts at that point. I don't see the boot menu I normally see that lists the opportunity to boot single-user; disable ACPI; and so on. Has anyone else experienced this? Is this a mismatch between gptzfsboot and my current pool version? (Gptzfsboot includes the message I'm seeing.) Am I supposed to rebuild and replace gptzfsboot every time the pool version is updated? (There was no advisory in /usr/src/UPDATING concerning this, nor do I remember seeing it elsewhere.) Yes, you're running a version of gptzfsboot that only knows how to run version 13 and below. The commit that brought in version 14 support also bumped the version number for gptzfsboot though it doesn't look like any of the code changed; perhaps version 14 doesn't change anything that gptzfsboot cares about. Try rebuilding and reinstalling gptzfsboot and zfsloader to see if that helps: cd /sys/boot make cleandir make cleandir make obj make depend make all make install gpart bootcode -p /boot/gptzfsboot -i 1 /dev/somedisk Of course adjust the gpart command for your setup.
