unfortunately that and the mini-howto are both very much outdated. Many of =

the stuff it mentions (like mkraid, /etc/raidtab) is not part of the =

distro anymore. You use mdadm nowadays. Those parts that contain mdadm =

commands are still valid.

Does this "Silicon Image SATA controller" not include Hardware RAID by =

chance? =

The basic steps for software-RAID are:
- decide about the partitions the RAID devices will be based on
- if it is used only for data you may probably want to have just one RAID =

partition:
mdadm --create /dev/md0 --level=3D1 --raid-devices=3D2 /dev/sda /dev/sdb
(I assume you can use sda and sdb. I always use several RAID partitions, =

so I never used the whole disk.)
put LVM on it:
  pvcreate /dev/md0
  vgcreate myvolumegroupname /dev/md0
  - creates vg myvolumegroupname on it
- start adding your logical volumes:
  lvcreate -L50G --name myname myvolumegroupname
  - adds a 50G logical volume named myname
  - format that lv:
    mkfs.ext3 /dev/myvolumegroupname/myname
- copy any data you like from the old drives
- add the mount points to fstab
- if you don't boot from the RAID partition you are done now

I recognized the switch must have been happened once I started getting =

I'd say you want to set prompt 0 if you don't want a prompt. A short
timeout should basically do the same, but an 0 sometimes means
"indefinite".

That very fedoraforum ? After all, there may indeed by something
different/new in that isolinux. ;-)

Of course, it's the current state of affairs as we think we know it.

I'm still having a problem with this software-RAID setup. I restructured
the disk layout, so that I have the exact same partition layout on both
disks. But now I cannot boot from the new md device.
The important devices are:

/dev/md0 with /boot (made from sda1 and sdb1)
/dev/md2 with / (made only from sda1)
/dev/sdb2 with / (to be added to md2 once booting from md2 works)

The problem is that if I boot the kernel into /dev/md2 it errors out with
"cannot mount /dev/root" when switching root. I can boot fine by using the
/ filesystem on /dev/sdb2. initrd contains raid1.ko, so the mdraid driver
is not missing driver.

Any hints what could be wrong?

Anyxone is able to loghin anytime, if youw ant to see it that way ;-) But
the system needs the ressources to make this happen before the timeout ;-)
It might also not be a CPU issue, but a bandwidth issue. If bandwidth is
occupied by other users it may take a time for your packets to get thru.
In any case, you may want to lower the load for that machine or give it
more "power" if you can. If you cannot login as root with ssh because it
times out this also means that the others experience a less than optimal
performance.

Yeah. The point behind my asking was if one would be able to run
RHEL/CentOS 6 as a dom0 - as it is derived from Fedora and reflects the
available bits at the time of the OS freeze. In other words, if there is a
normal upgrade path concerning Xen from RHEL/CentOS 5 to 6 or not. So, at
the moment it looks like you can't run RHEL 6 as a dom0, but this may
change until it's release depending on the upstream (kernel.org?) kernel
having the relevant xen bits in time for an RHEL release (which is
promised for 2.6.29 or so at the moment).
You can probably run RHEL 6 paravirtualized on a RHEL 5 dom0.
Correct interpretation so far?

do you *really* need this package? If not, uninstall it and your problem
is gone. I didn't check, but I assume this package is somewhat older than
your to-be-updated 94.1 rpmforge packages and not compatible anymore.
AFAIK the clamav perl module isn't really maintained for some time now, so
there is nothing new to package.

but they may well be your only ressource here, bioinformatics surely isn't
a widespread task given the whole userbase ;-)
You may want to contact the maintainers of such a repo and ask if they can
provide updates more often. I gather that, apart from time constraints
etc., they may also need some encouragement as they are not catering too
so many users.

Bored of naming yourself whoami or lingu? Or just realized that you posted
a few off-topic questions too many with these names?
Please stop abusing this list for your RHEL3 cluster problems. Thanks.

Sam, please don't abandon threads you initiated yourself about the same
topic, this is noob behavior. You should know better by now. You waste
other people's time as they cannot know all content of all threads.

The dovecot in CentOS 5 exhibits the same problem when hammered by
dictionary attacks. Is the atrpms version newer?
