Re: ZFS on top of GELI / Intel Atom 330 system

Well, my current setup is using an old 2GB CF card, so read/write speeds
suck (14 and 7 MB/s, respectively, IIRC), but then again, there are not
many actual read/writes on / or /usr for my setup anyway.

The 2x 8GB USB sticks I would of course use to gmirror the setup,
although I have been told that this is rather excessive. Modern flash
media should cope with enough write cycles to get you through a decade.
With /var being on GELI+ZFS this point is mood even more, IMHO.

A recent 8GB Sandisk U3 stick of mine manages to read/write ~25MB/s
(working from memory here), so this is pretty much the maximum USB 2.0
is giving you.

Cheers,

same here on 7-stable (csupped yesterday)
i've followed the same steps, but i've used gpt as explained in the
first mail. the same exact steps worked perfectly on 8-current in
virtualbox

This is the file /boot/loader from 7.2-STABLE which is wrong.

You can find a copy from 8.0-CURRENT and a script that I tested on a USB 
key) and is running for me:

http://verbier.restart.be/xfer/boot-zfs/

Put this directory somewhere, eg /tmp/boot-zfs

and run the script eg:
`cd /tmp/boot-zfs && sh -x make_usb_key.sh da6 kingston`

good luck

/boot/loader can't load kernel if too many pool/devices

Hello,

During my tests (succesful) to directly boot from ZFS (with zfsboot and 
gptzfsboot) I encounter the error "can't boot 'kernel'" if too many 
devices/pools are connected to the machine. In my case:

2 SAS disks with 2 pools
2 SATA disks with 2 pools
1 USB key with one pool

`heap` command:

Active Allocations: 171/173
536576 bytes reserved 527800 bytes allocated

`ls` command:

open '/' failed: too many open files

If I reboot without the USB key all is OK.

If I reboot from the USB key after disconnecting 2 disks all is OK.

By the way, the /boot/loader in 7.2-STABLE don't work, complains about 
forth not found.

The previous tests were made with 7.2-STABLE (May 31) with /boot/loader 
from 8.0-CURRENT.

replacing /boot/loader with yours did the job

Re: ZFS booting without partitions

Odds are that there are more changes that were made in HEAD to the
loader that need to be MFC'd.

Unnamed POSIX shared semaphores

Hello,

According to sem_init(3), we can't have shared unnamed semaphores.
However, the following code snippet seems to work just  fine:

-- cut here --
        sem_t semaphore;
        if (sem_init(&semaphore, 1, 10) < 0)
                std::cout << "Couldn't init semaphore: " <<
strerror(errno) << std::endl;
        if (sem_wait(&semaphore) < 0)
                std::cout << "Couldn't decrement semaphore: " <<
strerror(errno) << std::endl;
        int val;
        sem_getvalue(&semaphore, &val);
        std::cout << "Value is " << val << std::endl;
-- and here --

Is this a case where sem_init() silently reports success, or should be
the man page get an update?

Thanks,
Vlad
