Where are the BSD Licensed “Enterprise Filesystems”?
A very simple question.
Where is the “Enterprise Filesystem” licensed in a pure BSD way?
I know ZFS has been implemented by OpenSolaris (well yeah…that’s the origin of ZFS) as well as FreeBSD but the CDDL is not without critique in the BSD community. The OpenBSD people consider the CDDL even more restrivtive than GNU/GPL.
So a question to all the guys and girls who are able to create a filesystem (I can’t my coding skills are nowhere near to be able to create one), where is the BSD licensed filesystem with all the new features that make a hype?
I’m thinking about stuff like this (thou maybe not complete, somebody may have an absolutely usefull new idea that obsoletes all these features
- Snapshots (BTRFS, ZFS)
- COW (Copy on Write) (BTRFS, ZFS)
- Volume Management built-in (BTRFS, ZFS)
- RAID (like) features built-in the filesystem (BTRFS, ZFS)
- Really large maximum filesizes and*
- Really large maximum filesystem sizes*
*This may not be a Problem now, but I do get why Sun chose to make ZFS a 128-bit filesystem
RE: Is there a best distro? (LinuxJournal)
LinuxJournal is asking for the best Linux Distro, first I thought
It’s actually quite easy to answer (especially to someone who will understand the implications):
There is no “best Linux”
Just asko what’s the best commercial Unix out there. One could
say: “They all start at the same point” it’s a kernel and some
toolset you can then use and (re)script to your needs.
The best ist actually the one that meets your requirements best.
- Cheap?
- Supported?
- Small?
“All of the distributions start from the same point”
I think that’s just plain wrong. Yes they do have the same kernel (do they really? – Debian GNU/kFreeBSD). But even switching from Ubuntu to Debian or vice versa has a lot of hurdles to take (“/etc/inittab” on Ubuntu?) - Upstart in Debian/Stable?
I’d rather suggest FreeBSD or OpenBSD (4.6 is just out, I suggest everyone to give it a try) - or is crucial because choosing between the 2 is (IMHO) even wider apart than choosing between RHEL and Debian. Note: I suggest this iff[sic] you want to stay in an enviroment that stays mostly the same thruought all servers and desktops
FreeBSD is FreeBSD is FreeBSD – on every box.
Linux is not “just Linux” from that point there’s just too much diversity among the distros. Even with a single Distro you can have large differences, of course you can take any BSD apart so that it won’t look like the original distribution anymore, but staying within the universe of best practices you won’t have as much diversity between FreeBSD installations as between Linux installations within a single distribution.
Selection of rich applications
The key word here is Selection. Compare RHELs selection to Debians selection. You wouldn’t think that an enterprise grade distro doesn’t even have Nagios in the repositories - aren’t the enterprise people monitoring their servers too?
My choice?
Simple, give me the problem description and I’ll have a look which of the distributions (or even non-Linux – read BSDs, or even non-FOSS) solutions will suit best. It doesn’t help to get RHEL if they don’t support the software you need, but it’s neither helpful to stay with Debian if you need proven Enterprise grade support contrancts with 4 hours of maximum time to react. (Btw: OpenSolaris does have the option to buy support from Sun)
Of course that would be only the start of a discussion with someone who already knows enough about *NIX to discuss on such a Level. As you said dear LinuxJournal:
This was not someone who is unfamiliar with technology, or UNIX for that matter, but someone who is one of us
µ-awk
My personal µ-awk tutorial, just some notes I like not to forget…
Print the average of a column:
# grep daemon_with_interesting_column_eight daemon.log |\
awk '{sum+=$8} END { print "Average = ",sum/NR}'
Print the average of a column fullfilling a constraint:
# grep daemon_with_interesting_column_eight daemon.log |\
awk '/$8>=0.02/ {sum+=$8} END { print "Average = ",sum/NR}'
I need a Wiki (or two, or three) – Quick!
OK so you need a Wiki in your company? – Not much of a problem just grab a copy of some wiki and there you go. Now that is fine for very small companies. You may need to have a Wiki for each project or departement and have some user rights within those Wikis. What are you gonna do? Create a whole new instance all the way thru everytime? I recommend a Wiki-Farm!
Let’s have some requirements:
- ACL or any kind of permissions for pages
- Shared User Base (mentioned below as an exercise to the reader…)
- Quick Setup of new Wikis (more…)
Numerical Keypad not Working? – Here’s a Solution(TM)
So i run Debian/Unstable on my workstation. It works fine 99% percent of the time but recently the numerical keypad stopped working. I have no idea what caused it but somehow the keyboard settings from Gnome have been modified.
The problem was that under “System” -> “Preferences” – > “Keyboard” under the “Mouse Keys” tab there’s an option “Pointer can be controlled using the keypad“. This option was checked.
Took me quite a while to figure this out but now I can happily type my numbers on the keypad again.
Here’s the screenshot (mostly for my own reference) where to find the option:

Happy SysAdmin Day!
Today is System Administrator Appreciation Day.
Be nice to your friendly SysAdmin neighborhood, we work all year hard to give you good service and help you solve problems. We might seem grumpy at times but take that with a sense of humor, after all we are the ones who have to get up at 0300h AM to fix the servers.
BTW: System Administrators aren’t mainly there to fix things, we are here to make sure things don’t break
Adventures in CentOS-Land (Part 3)
Let’s get to work with CentOS5 now that we have set up the yum repositories and are able to install all the software we need. As a short reminder our requirements listing again. So let’s continue from last time…
Our requirements are the following: (more…)
Adventures in CentOS-Land (Part 2)
OK let’s see what’s going on with our CentOS mail host from last time. First let’s check that we don’t have too much listening on public interfaces after all we only need SSH, SMTPs, IMAPs and HTTPs when everything is set up… (more…)
Adventures in CentOS-Land (Part 1)
So I have to set up a dedicated mail server for my boss’ private use. Since we wanted to completely seperate this private use server from our infrastructure “we” (actually our billing department) decided to get a GoDaddy server (a dedicated one). The account was set up and the details were forwarded to us – as happy admins of mostly debian we don’t have to deal with non-debian system too often so we were not exactly happy to find only Fedora, RHEL or CentOS as available Linux options. Anyway the account had already been paid for so we went to set it up.
Here are the requirements: (more…)
Update: Firefox 3.5 officially released
A small update on the earlier download of Firefox 3.5.
The Mozilla product page of firefox is now officially stating that Firefox 3.5 is available. (more…)
