 Is this a feature, or a bug?

If you're at the console you can usually just push the reset or power
button *anyways*, so it's a non-bug. I believe you can edit the
appropriate entries in /etc/pam.d if you really want to change this.

Not necessarily true.  Lots of people use remote KVM's :)  So just
because someone has access to the console does not mean they have
physical access to the server.

Thanks, John, but is that really the whole answer?  Once it's ext3 it
can be put into a volume group with no further ado?

I would think that (particularly with a striped LVM such as Johnny
mentioned) there has to be something else invovled.

You would need to copy the info off, create partitions, then PVs, then
VG(s), LVs ... then use mke2fs -j to make the file systems on the LVs
... then copy the files back.

That's true, but you can push CRTL-ALT-DEL and the computer reboots, even if

 - What kind of performance can we expect from an LVM group as compared

OK, the answer to this question is ...

RAID and LVM can be used together, or individually.


Thanks for confirming that, though in this case it's a hardware RAID
so I wouldn't expect LVM to need to treat it as anything other than
big disk.


If you have 2 or more drives that are the same in the machine, you can
Stripe your LVM.


Could you clarify that are the same?  The primary point of this
excercise is to make the filesystem resizable.  It's already
impossible to buy exactly the configuration of new hardware that's
already attached; we wouldn't want to be limited to adding identical
extents every time we expanded the storage.


LVM done this way is quite fast ... but obviously you would need to
provide another way to protect your data.


Presumably using hardware RAIDs as the physical volumes would take care of that.

Thanks for the information.

Can't C-A-D be filesystem trapped to prevent the system from rebooting 
with that key combo?   If so, that could negate that option if the fs is 
configued as such.

Re: [CentOS] Seeking pointers to info about LVM migration and performance

2007-07-08 Thread Bart Schaefer

On 7/8/07, Johnny Hughes [EMAIL PROTECTED] wrote:

Well ... if you are using hardware RAID, then striping LVM will likely
not give you any benefit speed wise.  (Unless multiple controllers are
used and read/write can be done in parallel).

The speed benefit happens if LVM can stripe the sectors to SATA or SCSI
drives where simultaneous read/writes can happen.  With hardware RAID,
the controller normally handles all that, so LVM striping is not
normally done.


What we have is a hardware RAID enclosure that already has all the
drives it can handle, and is approaching capacity.  So what we're
currently considering is adding an entire additional RAID device and
using LVM to combine them into a VG as a pair of SCSI drives.  So it
appears we could configure them as either striped or linear, and LVM2
would handle growing even a striped configuration if we add a third
RAID later.

A performance boost from LVM striping would be a bonus, but what I'm
really asking is whether there's a penalty for LVM linear.

I hadn't considered, though, that we could also rotate larger drives
into the existing RAID and then grow the filesystem once they were all
upgraded.

You can change the behavior ov C-A-D in /etc/inittab. I changed it to
ca::crtlaltdel:/bin/echo Nix da!
to prevent a reboot if I push the keycombo faulty.

Yes, it works.
The DNS search suffix matters.

 Hi

 I am trying to use Bind as named. And I have successfully set up a
 chrooted bind.

 Anyway, I cannot have it resolve www directly.

 For example, when I am using nslookup, when enter www.example.com, it
 will resolve. But when enter www, it will not.
 I want to have www resolve to www.example.com, what should I do? I
 have already set $ORIGIN in the zone file, but it does not work.

 Thanks.

 If you have created a zone file for example.com
 in /var/named/chroot/var/named/example.zone

 All you need to do is to add the entry below to your zone file
 www A   ###.###.###.###

 This is what I did anyway, and it is working great!!

Not quite This will only add a www record to your domain... What
I think the original poster wants is to use the DNS Seach suffix
functions of DHCP.

This will add the prefix automatically when the host tries to search
for a DNS entry...

$ cat /etc/resolv.conf
search example.com
nameserver x.x.x.x
nameserver x.x.x.x

This will get you the desired results. You set it in your dhcpd.conf
file as so:

option domain-name  example.com;

[CentOS] DTLS for Centos?

Is DTLS available for Centos?  Either Centos 4 or 5.

DTLS is TLS over UDP.  Highly valued to protect SIP traffic.
