I don't see that on VMs that I manage. Some of the physical machines
that I manage do have duplicates in the device.map.

Question re: CentOS-6.0, KVM, and /dev/sr0
I am experimenting with KVM and I wish to create a virtual machine
image in a logical volume. I can create the new lv without problem
but when I go to format its file system then I get these warnings:
Warning: WARNING: the kernel failed to re-read the partition table

Thank you all for your reports. Since it seems this is generally the
case with CentOS 7, does anyone also have access to RHEL 7 installations
to verify if this is the case with these installations as well?

Slow RAID resync
OK todays problem.
I have a HP N54L Microserver running centos 6.5.
In this box I have a 3x2TB disk raid 5 array, which I am in the
process of extending to a 4x2TB raid 5 array.
I've added the new disk --> mdadm --add /dev/md0 /dev/sdb
And grown the array --> mdadm --grow /dev/md0 --raid-devices=4
Now the problem the resync speed is v slow, it refuses to rise above

After more googling, I found this bug report with a very recent fix:
https://bugzilla.redhat.com/show_bug.cgi?id=1399487
It seems to me that this may be relevant in our case.
If so, may it be that this fix has not been rolled out to CentOS repos yet?

Define custom ldap libraries when building Dovecot
Hello,
I would like to compile Dovecot using custom ldap libraries, located at
a particular custom system location.
How should I alter the config process to specify that the include dir is
"/usr/local/openldap/include" and the lib dir is
"/usr/local/openldap/lib64" and not the standard ones (/usr/include/ and
/usr/lib64/ respectively) on RHEL/CentOS 5 (x86_64). Note that

Urgent: Need to change the location of a directory tree
Hi,
I am running CentOS 7 (fully updated) on a VM. This has a mounted nfs
share (via fstab) (which mounts a remote storage system) on which we
have created the home directories of 2 users
Here are the home directories:
/mynfsmount

|--/user1
|--/user1
We want to move this whole branch from the mounted NFS share to the
local disk.
What is the way to do so?
Would it be enough to create a

remote | local blocks in protocol settings
Hello,
Where can I find detailed documentation on how "remote" & "local" blocks
are used in protocol configuration to provide specific settings for
particular IPs/Names?
I've been searching around (wiki2, Google) but I found very few things.
I also checked in the conf.d directory of the installation and couldn't
find anything.

It's /dev/vda in my case:

Disk /dev/vda: 21.5 GB, 21474836480 bytes, 41943040 sectors

Problem with ldap / quotas

I am trying to enable per user quotas, but I get the following error:

Problem solved - at least in my case - by changing the NFS Export
Options (of the NFS shared directory, at the data storage system) from
secure to insecure. That is, I changed from:
rw,no_root_squash,no_all_squash,secure,nolog
