If you use the disks only for /var/snd data store this will definitely
work. But in that case i would leave the drives untouched by the
installer and create the raid later.
In case you also want other partitions for example of the system to
reside on the same drives this will make problems because you can either
use gpt or dos partition tables per drive but not both at the same time.
It still can work though... here would be the steps to do this:

 - create a DOS partition table on both disks and install the system on
   the RAID created by the installer - leave the vast majority of the
   disk unpartioned -> ther is no point in creating a partition which
   you will through away later
 - log into the new system and use the following command to remove on
   of the drives from the raid:

# mdadm /dev/md0 --fail /dev/sda1
# mdadm /dev/md0 --remove /dev/sda1

 - use parted to create a gpt on /dev/sda and create 1 small (~32MB)
   partion and set the flag bios_grub on it. Create another partition
   for the system and one for /var/snd and set the raid flag on both of
   them. The system partition must have the same size of the system
   partition on the other drive which is still use - you can check this
   with: # parted /dev/sdb -- unit s print

   # parted /dev/sda
   > mklabel gpt
   > mkpart
  > name = 
  > fstype =

   > mkpart
  > name = 
  > fstype = 
  > start = use default aka just hit enter
  > end = -1
   > set 3 raid on
   > quit

 -  now you need to re-add the new system partition to the system raid

# mdadam /dev/md0 --add /dev/sda2

 -  create the raid for /var/snd

# mdadm --create /dev/md1 --level=1 --raid-devices=2 /dev/sda3

 -  wait for the system raid to resync:

# while sleep 1; do clear; cat /proc/mdstat; done

 - remove the other system disk from the raid:

# mdadm /dev/md0 --fail /dev/sdb1
# mdadm /dev/md0 --remove /dev/sdb1

 - now use parted and create the complete same setup for sdb as sda

# parted /dev/sdb
.

 - add /dev/sdb partitions to both raids:

# mdadm /dev/md0 --add /dev/sdb2
# mdadm /dev/md1 --add /dev/sdb3

 - reinstall/reconfigure grub

# grub-install /dev/sda
# grub-install /dev/sdb
# update-grub

 - before you reboot you should at least wait for the system raid to
resync.

 - reboot

Now you can create a filesystem on /dev/md1 or a LVM or wathever you
want... actually the reboot is not really necessary but as you had to
redo the bootloader setup it's nice to see whether the system still boots.

 Not that specifically, but I did install CentOS-6 on a 3TB drive recently 
using that same installer.
 It will do it just fine, but you have to do it as a custom, I forget what they 
call it, when choosing
 the disk and partition.

 Also be aware that the CentOS boot loader ( grub ) can't work with disks 2G or 
larger !!
 It will be necessary to create a much smaller ( say, 500MB ) boot partition to 
work around
 the grub bugs.
 Grub will tell you it installed fine, but will otherwise never boot.

Re: [RDD] imminent HD failure from large rdimport

[Tom Van Gorkom]

Disk utilities report 102 bad sectors and over 13k read error rate. I agree
- better replace it quickly.

But why after importing does the used memory stay high, and why did the CPU
keep working? Would a failing drive cause the CPU to keep trying to find
good sectors and good data to read? The disk isn't near full.

It’s completely normal to see +90% usage of RAM on a Linux box.  That’s because 
Linux aggressively caches file data (see the ‘buff/cache’ counter in top(1)).  
It has nothing whatever to do with disc failure.


> Do I need to replace the HD or can I run repairs and be confident?

I would backup my data and replace the drive.  Immediately.

 Irrelevant.

 Myself, I'd be looking at the relocated counts in the S.M.A.R.T. data,

 I don't care what the thing is "rated" for, speaking as a disk recovery guy,
 back it up RIGHT NOW !!!

 Don't call your mom.

 Back up that drive immediately !!

 If it doesn't fail in the next hour or so, great, but it very well may.

[RDD] GPIO Permissions

[Michael Barnes]

Setting up a new Rivendell box that has a Measurement Computing PCI DIO-24
card installed.  When I fire it up, I find that it doesn't read contact
closures.  Using gpitest I get a popup box that says "Can't open GPIO
device." I check /dev/gpio0 and find the permissions only for root.  I
chmod it to 777 and everything works fine.  However, on rebooting the
machine, the permissions reset and the relay contacts don't work again.

How do I permanently change the permissions so they stay in place after a
reboot?

This is a CentOS 6 Appliance install.

Thanks for your ideas.

 By "only for root" I suspect you mean owner only, and it's owned by root ?

 Or do you mean owner and group root ?

 I suspect a udev rule, or something along those lines.

Sorry no easy solution but an very likely explanation why the installer
does this:  Dos Partition labels have a limit of 2TB. For drives bigger
than that you would need to create a GPT. Manually this can be done
using parted [1].
Once the partitions are created you can mark the partitions for RAID
using the following command:

sudo parted /dev/sda -- set raid 1 on
sudo parted /dev/sdb -- set raid 1 on

This assumes you have two drives with one partition each which should be
used as raid.

The article behind the link is quite old and says that on Debian/Ubuntu
you need to rebuild your kernel - forget that. Debian/Ubuntu supports
GPT since several releases.

This is also wrong. The correct command would be:

sudo parted /dev/sda -- set 1 raid on
sudo parted /dev/sdb -- set 1 raid on

the '1' means the partition number if you have more than one partition
this is likely a higher number...
You can see which partitions exist on your drive using the following
command:

sudo parted /dev/sda print

No Rivendell 3 at the moment.  There is a (presently somewhat stalled) BA3, for 
which I am currently evaluating alternative desktops (as I’ve come to the 
conclusion that GNOME 3 is a complete and utter basket case).  I’ve been using 
it for a couple of months now as my default environment and it *doesn’t* get 
any better.  Quite the opposite actually.

Stay tuned…

Cheers!

Re: [RDD] Rivendell broadcast appliance installer 2.6.5.1 seems to be allergic to 3TB disk drives???

[Rick Thomas]

Thanks, Christian…

Your reply is very helpful!

Is it possible to run parted (or anything else capable of creating a GPT 
partition table) while in the installer?  In Debian I know that hiting -F2 
gets me a text shell console.  But I’m new to CentOS and the Anaconda installer 
— does it have a similar feature?

Alternatively, I guess I could do the installation with the 3TB disks but using 
only 2T on each, then after the installation is over and it’s booted into the 
installed system, I can manually re-partition the disks using parted and a GPT 
table.

Do you think that would work?  Can you think of any “gotchas” I’m likely to hit?

Thanks!
Rick

Is there a Rivendell 3.0 in the works? I must have missed that post.

[RDD] imminent HD failure from large rdimport

[Tom Van Gorkom]

Help!

We are finally to the point of moving all our audio files into the new
Rivendell system. I left it importing 1100 audio files last night (probably
5 hrs) using rdimport and when I arrived this morning all imported fine
with the standby having copied them all but the HD light was continuously
lit on the master server and while I tried to see what was using all the
CPU and memory, the disk utility gave the warning of an imminent hard drive
failure. It is a nearly new 4TB WD NAS rated drive. The problem seems to be
that the 8GB of RAM loaded up to 95% and stuck there with the CPU running
continuously at about 50% on the master server. The RAM of the client from
which I ran the import also loaded up to 90% but its CPU was nearly idle.
The standby server had no issues. Rebooting cleared the RAM but the failure
warning remains.

Do I need to change some mysql settings? I am using the provided my.cnf
file.

Do I need to replace the HD or can I run repairs and be confident?

Thanks,
