Grow LUN and add partition to VMware Virtual DIsk for Red Hat

Red Hat 5.6 running on VMware vSphere.

Grab a snapshot before messing with any of this.
This procedure is slightly different if you are messing with /dev/sda (if that's where your / is)


# Determine what VGs are assigned to the disk you are messing with...
#   in this case... /dev/sdb
for PART in `fdisk -l /dev/sdb | grep ^/dev | awk '{ print $1 }'`; do pvdisplay $PART | grep VG\ Name | awk '{ print $3 }' | sort -u; done
vg_test

# Figure out what volumes are mounted on that VG
df -h | grep SCOREDATA

umount /SCORE_Data
lvchange -a n /dev/SCOREDATA/SCORE_Data
vgchange -a n SCOREDATA
blockdev --rereadpt /dev/sdb
fdisk -u /dev/sdb
# n p 2 t 8e w
partprobe /dev/sdb
blockdev --rereadpt /dev/sdb
fdisk -l /dev/sdb
vgchange -a y SCOREDATA
mount -a
pvcreate /dev/sdb2
vgcreate SCOREARCH /dev/sdb2
FREEPE=`pvdisplay /dev/sdb2 | grep Free\ PE | awk '{ print $3 }'`
echo $FREEPE
lvcreate -l+${FREEPE} -nSCORE_Archive SCOREARCH
mkfs /dev/SCOREARCH/SCORE_Archive
cp /etc/fstab /etc/fstab.20130319.jr
echo "/dev/SCOREARCH/SCORE_Archive /SCORE_Archive ext4 defaults 1 2" >> /etc/fstab
mount -a
chown jboss:jboss /SCORE_Archive/

P2V using dd for KVM-QEMU guest

Preface: I have certainly not exhaustively tested this process.  I had a specific need and found a specific solution that worked. Situation:  I was issued a shiny new laptop running Red Hat Enterprise Linux 7 (with Corp VPN, certs, Authentication configuration, etc...)  The image was great, but I needed more flexibility on my bare metal.  So, my goal was to P2V the corporate image so I could just run it as a VM. * Remove corporate drive and install new SSD * install corp drive in external USB-3 case * Install RHEL 7 on new SSD * dd old drive to a disk-image file in a temp location which will be an image which is the same size as your actual drive (unless you have enough space in your destination to contain a temp and converted image) * convert the raw disk-image to a qcow file while pushing it to the final location - this step should reduce the disk size - however, I believe it will only reduce/collapse zero-byte blocks (not just free space - i.e. if you de...

Sun USS 7100 foo

TIP: put ALL of your LUNs into a designated TARGET and INITIATOR group when you create them.  If you leave them in the "default" group, then everything that does an discovery against the array will find them :-( I'm struggling to recognize a reason that a default should even be present on the array. Also - who, exactly, is Sun trying to kid.  The USS is simply a box.. running Solaris .. with IPMP and ZFS.  Great.  If you have ever attempted to "break-in" or "p0wn" your IBM HMC, you know that there are people out there that can harden a box - then.. there's Sun.  After a recent meltdown at the office I had to get quite intimate with my USS 7110 and learned quite a bit.  Namely: there's a shell ;-) My current irritation is how they attempt to "warn you" away from using the shell (my coverage expired a long time ago to worry about that) and then how they try to hide things, poorly. I was curious as to what version of SunOS it ...

Extending SNMP to run arbitrary shell script

Why are we here... This is not likely something I would have pursued under normal circumstances.  I happen to be working for a customer/client who is not afforded a lot of flexibility to accomplish their goals.  In this case, the rigor is justified.  They have to sometimes be fairly creative with how they solve problems. In this case they would like to utilize an existing snmp implementation to execute a command (or shell script) on a remote system.  They came to me with the idea of using Net-SNMP extend. https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/sect-System_Monitoring_Tools-Net-SNMP-Extending.html NOTE:  This is NOT a good implementation strategy in the "real world"  it will simply allow you to test the functionality.  There are a TON of security implications which would need to be taken in to consideration. Implementation Steps: [root@rh7tst01 ~]# yum -y install net-snmp net-snmp-utils ...
