Re: [BLUG] RAID-like redundancy for a linux?

Linux has had software RAID for years and years. There are some idiosyncrasies, but overall it works real well. (A Google search of "software RAID Linux" should cover all the needed info.)

Due to the nature of the RAID process, the usable space is the lowest common size of the drives. (You don't need to worry about differing disk geometries these days.) If the space difference is large, you can still use the extra space as non-RAID storage.

You don't need weird/custom kernels, and the easiest way to set this up has been as an option in the installation process -- it has been available for the past decade or so. (Ubuntu Server, like Debian before it, has this as an option. I am less confident about some of the GUI install processes.)

In Linux software RAID creates a block device. You can pretty much put any filesystem you want on it.

Re: [BLUG] RAID-like redundancy for a linux?

If you are interested in RAID-5/6, Ben, you should definitely look at a hardware RAID card to do this. RAID-5/6 is not safe to do in software alone, unlike RAID 1, 0, or 10 (although I would not recommend RAID 0).

I love ZFS, but I'm unsure of its future under Oracle's leadership. Ironically, it seems like if you want ZFS, short of shelling out the dough for Solaris, your best bet is FreeBSD/FreeNAS where it seems a lot of people have been using it with no reported difficulties. There is also OpenIndiana, but I'm not convinced that its backing and support is all that great to really assure me that the future of some sort of non-commercial version of ZFS running in a Solaris based OS is in good hands. With many players interested in and working on BTRFS, it could also be that ZFS is eventually phased out for BTRFS  once it is deemed production ready.

However, since you are talking about Linux, all of this FreeBSD/Solaris stuff is moot. There is no great way to get ZFS in Linux now.


I would look at software RAID 1 or 10 in Linux as has been said, RAID-5/6 if you don't mind buying a RAID card (which includes a battery to perform the last of the writes in the case of a power failure, which is what makes it "safe").

How many drive bays do you have to work with, Ben? Is performance an issue here, or are you just looking for basic storage and reliability?

For the last two years my home media server has run Mandriva Linux
(yes, I know, I'm the last person still using Mandriva :-) ). I have
it set up currently as a RAID-6 system with 8 2TB drives along with 2
more hot spares, all formatted ext4. The one time a drive failed,
about 1.5 years ago, it automatically shut down the bad drive, pulled
in a hot spare, and rebuilt the missing drive, all with no attention
from me.

If you have a lot of data, I always recommend RAID-6 over RAID-5. With
2TB drives, it will take 8 to 10 hours to rebuild from a drive
failure. With RAID-5, that's 8 to 10 hours where you have no
redundancy to fall back on. And if you don't have hot spares, RAID-5
leaves you with no redundancy until you happen to notice there is a
problem. I don't like either of those scenarios.

I honestly don't know if it would work with differing drives sizes or
not. It was easier, in my opinion, to just stick with the same size of
drives right out of the gate.

I don't know of any reason you couldn't do the same with Ubuntu.

[BLUG] Ohio LinuxFest 2012 Registration is Open for Business

It's time to make your plans to attend the best Ohio LinuxFest yet. We
are celebrating our tenth year with a great lineup of speakers, great
technical training at the Ohio LinuxFest Institute, a new training track
for folks just starting with Linux, parties, BOF sessions, vendor
exhibits, and all the things you expect from Ohio LinuxFest.

This year we are trying something a little different with our
registration. The Enthusiast registration is still free, the training
registrations are the same. But in place of the Supporter registration
we have created an a la carte menu of supporter options so you can
purchase the items you you are interested in. On the Registration page
you will see a link for _Supporter Add-Ons_ which will let you purchase
a ticket for the Saturday party, a T-shirt, register for the Diversity
in Open Source workshop, or make a donation to support OLF. And we may
add items in the future, so check back later for other items.

To register for Ohio LinuxFest 2012, please go to
http://ohiolinux.org/register

[BLUG] Need a junk AM2 motherboard

Anyone have a junk AMD2 motherboard laying around? I actually only need
the plastic cooler bracket from one. The yellow part as shown here:

http://www.amazon.com/Gino-Retention-Bracket-Yellow-Socket/dp/B007PPEUPE

I built this machine for a fiend three years ago and it just came back
to me today. I never have seen this before. First time for everything.

Re: [BLUG] NAS (for Ubuntu 8.4 and 10.4) recommendation?

Thanks, everybody, for the reply. I talked to the owner and
he actually was thinking abut NAS instead of SAN. ;-) So I
have changed my subject line. Any recommendation for small
scale NAS?

Best,

Yes, however for a SAN that is small. Where I work we have SANS near
100TB. And we're on the low end compared to some very big companies.
There really is a lot of waste though. People don't know how to properly
manage their data.

I once calculated that at the rate we're going, by the time I'm 85
years old (2061). We'll be in the yottabyte of storage era. Of course
there are all kinds of obstacles to get there, but so where there in
getting to GBs and TBs.

http://suso.suso.org/xulu/A_Yottabyte_of_storage

110YB would approximately be enough to record the entire lifetime of
every person who has ever lived in HD.

I would also consider NAS appliances. I've heard decent things about
QNAP products.

Re: [BLUG] SAN (for Ubuntu 8.4 and 10.4) recommendation?

Have you already dismissed a direct attached storage product?  SANs are nice for the right situation, but they are very pricey.  It might be overkill for a small lab type situation.

I've heard good things about the Dell SANs, but I've never used them myself.

Hi,

Anyone in the group have any recommendation of a small scale SAN that

[BLUG] gnome-terminal, xfce4-terminal, terminator and others are unsafe

I'm trying to release this many places so that people see it and
take care of it for themselves. Terminal emulators that use the
libvte library, which include gnome-terminal, xfce4-terminal,
terminator and guake write their scrollback buffer history to disk in
the /tmp directory:

[BLUG] Mounting a network drive

Hi,

If anyone is up to doing a 'Mounting network drives in Redhat for Dummies' primer, I'd be most obliged.   My Googling abilities seem a bit suspect on the topic.

I have a Redhat server that I want to write backup files from to a QNAP NAS which runs some flavor of Linux.  I can't remember what it is off the top of my head and am on my way downtown to an appt with Dr. CrazyHorse but can get the info Monday if it's needed.

I can navigate to the share on the NAS from Redhat and have no access restrictions on that share at all but still don't seem to be able to write my backups to it. 

I'm hoping that if I mount a drive I'll have more luck.  I just can't seem to get the syntax correct.

Thanks In Advance!

Hi,

My friend has a Lenovo X201 laptop that might have a bad fan.
Unfortunately its warranty has expired. So he is looking for
a Lenovo authorized deal who can take a look at it and repair
it if needed. Local to Bloomington preferred but not limited.
Anybody has any recommendation?
