Configure LVM to gain access to the data on disks

Leave a comment

By prvnrk

Hello friends,

We had to upgrade RHEL 4.x to 5.7 so we took complete backup. Since DIRECT UPGRADE not possible, we rebuilt 5.7 from scratch.

We had lvm configuration on DATA disks in previous OS and now we need to configure such that we should be able to have same old LVM configuration (like VGs and LVs etc.) so that we could access the data on those volumes.

Could any kind soul provide me step-by-step on how to do this? (Yes, I have backup of /etc/lvm etc. of previous OS).

I thought of just copying Old /etc/lvm into new one and start lvm daemon. will it work?

TIA

Help for applying same actions to different directories with identical sub-directories

Leave a comment

By A-V

Hello all

I have a situation and would be grateful if you will help me… I am not sure whether it is even possible

I have few folders/directories —e.g. A – B – C -in my MAIN directory
for each of them I would get the data from folder called DATA and go through a long list of actions which involves creating new sub-directories.
So e.g. will run a program for A -> creating 5 new sub-directories – doing some calculations and getting some results out
the same happens for B and C
I have tried to put an FOR loop around it which seems to work if I only have one of them there as the address for the directories will get confusing as my program refers to sub-directories in the A,B,C

Code:
###for A
FILES="A/*"
for X in $FILES
do
FILES="data/*"
for X in $FILES
.
.
.
done
##for B
FILES="B/*"
for X in $FILES
do
FILES="data/*"
for X in $FILES
.
.
.
done

Now my problem is how to adapt it so when I am on MAIN, I can run all of them at the same time and related directories would be created inside each of them separately …
the Path seems something like this

Code:
MAIN/A/ -> data, id, count, count/result
MAIN/B/ -> data, id, count, count/result
MAIN/C/ -> data, id, count, count/result

I am not sure whether something like this is possible … or they might be a very simple solution but my mind is not supporting now
Thank you in advance
Anna

Hi…

I am trying extract data using 2 files..

1. Data file – DATA.TXT containing data to be extracted
2. Column file – LIST.TXT header column to be extracted

output not coming properly..

if the header field name matches with data file header extract data…this actually I wanted …

Code:
#!/bin/bash

DATAFILE=${1:-DATA.TXT}
COLUMNFILE=${2:-LIST.TXT}

awk -F, -v colsFile="$COLUMNFILE" '
BEGIN {
j=1
while ((getline 0) {
col[j++] = $1
}
n=j-1;
close(colsFile)
for (i=1; i<=n; i++) s[col[i]]=i
}
NR==1 {
for (f=1; f<=NF; f++)
if ($f in s) c[s[$f]]=f
next
}
{ sep=""
for (f=1; f<=n; f++) {
printf("%c%s",sep,$c[f])
sep=FS
}
print ""
}
' "$DATAFILE"

Code:
cat DATA.TXT
ID, head1, head2, head3, head4
1, 25.5, 1364.0, 22.5, 13.2
2, 10.1, 215.56, 1.15, 22.2

cat LIST.TXT
ID
head1
head4

sh extract.sh DATA.TXT LIST.TXT
1,1, 25.5, 1364.0, 22.5, 13.2,1, 25.5, 1364.0, 22.5, 13.2
2,2, 10.1, 215.56, 1.15, 22.2,2, 10.1, 215.56, 1.15, 22.2

and I want to display it as space separated ..

Code:
awk '{print $3,$2,$1}' FS="," DATA.TXT
whether here some changes can be done to get desired output

please help..
