Re: setup journaling for root partition

[s m]

thanks Warren, you're right but i want to set journaling in fixit
mode in fixit mode none of my partitions are mounted (mount
command show no partition) but geom returns error yet.

is there any way to tell geom that my partitions are unmounted?

Hmm I wonder if that's mostly down to the SAS drives seeking faster
or between ZFS and ext4. The only real way to tell would be to give both
boxes the same kind of drives.

Re: filesystem advice

[krad]

There isnt really a thing as better, just different. WHich is best for you
depends on your requirements and resources.

A zfs based solution would work on that system as its just serving a few
clients, and on the assumption that they arent to demanding it should run
fine. Bunging in more memory if you can will just make things better
though, just dont expect anything to amazing out of the machine. If the
data is important then all the data integrity features of zfs will be handy.

However if you need more speed ufs will be faster on that system, at the
expense of the advanced features of zfs.


Its really down to you to decide whats more important.

Re: linux_base-c6 && Skype 4.2

[Jerry]

According to the web site, these are the minimum requirements for a
Linux version of Skype 4.2.0.11

Skype for Linux

1 GHz processor or faster.
256 MB RAM.
100 MB free disk space on your hard drive.
Video card driver with Xv support.
Either a built-in or external microphone is required for voice calls.
An internet connection – broadband is best (GPRS is not supported for voice 
calls).
Qt 4.7 • D-Bus 1.0.0
libasound2 1.0.18
PulseAudio 1.0 (optional)
BlueZ 4.0.0 (optional)

I saw a post, I think it was SlashDot, that the FreeBSD kernel was not
robust enough to handle Skype. You might want to talk to the
developers. You can always download a clean distribution of Skype
from the web site and experiment with it.
