asked on
Configuration of lun in 2 partion and mounting to server
Hi Everyone,
I am having issue finding the luns configuration.
From the output of $df -h
/dev/mapper/olinux008_d1-o pt /opt
/dev/mapper/olinux008_d1-u serhome /userhome
The above are 2 partition made of of a single lun (storage)
I am really having hard time finding the configuration how this was being done.
I need to replicate same configuration on pre-productin server
Your help much appreciated.

Do you need thr step by step command to how to create the same filesystem layout in the another box or a overview would be enough?

Step by step is much appreciated
an overview on how the command need to be run and what they doing..
This will be great help for me
Thanks

Alright, First ask your storage team to present a 100 GB LUN to your box. Once they confirm then scan the new presented LUN to the box. Once the new LUN is available, a dm device will be created.
Run the below given commands to achieve your goal.
# pvreate /dev/dm-x
# vgcreate olinux008_d1 /dev/dm-x
# lvcreate -l 5120 -n userhome olinux008_d1
# lvcreate -l 20479 -n opt olinux008_d1
These steps will ctrate the same size of LVM as you require. After that you need to create the file system on that newly created LVs. If you require any help in that as well, please send me output of below given command.
# df -Th
Also update which linux distro you are using.
Run the below given commands to achieve your goal.
# pvreate /dev/dm-x
# vgcreate olinux008_d1 /dev/dm-x
# lvcreate -l 5120 -n userhome olinux008_d1
# lvcreate -l 20479 -n opt olinux008_d1
These steps will ctrate the same size of LVM as you require. After that you need to create the file system on that newly created LVs. If you require any help in that as well, please send me output of below given command.
# df -Th

I am trying to understand what i am doing.. I have gone through some notes now it make sense but have few questions
Q1- How do you check the lun is showing to OS after Storage team assign the lun to the server
Q2-Need clarification on this
#pvcreate /dev/dm-x <--- what this command doing
#vgcreate olinux008_d1 /dev/dm-x <-------here we creating Volume group
#lvcreate -l 5120 -n userhome olinux008_d1 <---- here its creating lv of vg of 20GB
#lvcreate -l 20479 -n opt olinux008_d1 <------ here its creating lv of vg of 80GB
Q3after the above command.how do i create file system and mounting procedure
thanks

Could you please tell me the make of the HBA so that we can tell you the way to scan the newly presented LUNs.
or If your box is not a production box then you can just reboot your system, LUNs will be available in your system after reboot.
Please update so that we can proceed further.

For Your Clarification:
Q2-Need clarification on this
#pvcreate /dev/dm-x <--- what this command doing
This command will create Physical Volume for the newly available LUNs. When we need to configure LVM filesystem then first we need to create PV the VG and then we can create LV.
#vgcreate olinux008_d1 /dev/dm-x <-------here we creating Volume group
Yes, You are right.
#lvcreate -l 5120 -n userhome olinux008_d1 <---- here its creating lv of vg of 20GB
Correct
#lvcreate -l 20479 -n opt olinux008_d1 <------ here its creating lv of vg of 80GB
Correct
Q3after the above command.how do i create file system and mounting procedure
Since you are using the ext3 filesystem so you need to create the same in this box as well. For that follow the below given steps.
#mkfs.ext3 /dev/olinux008_d1/opt
#mkfs.ext3 /dev/olinux008_d1/userhome
Now filesystem has been created and your LVs are ready to mount.
Since /opt is always there in linux box so we need to create /userhome mount point only. follow the command for the same.
# mkdir /userhome
Now follow the steps to mount the new LVs.
mount -t ext3 /dev/olinux008_d1/userhome /userhome
mount -t ext3 /dev/olinux008_d1/opt /opt
To make available these filesystem after reboot as well make the entry in fstab file for the same.
Hope you have everything with you. :)

It seems that LUNs are available in your box so Could you please show me the listing of /dev/mpath and /dev/disk/by-path.
# ls -lart /dev/mpath/
# ls -lart /dev/disk/by-path/
Show me output of fdisk -l.
# fdisk -l
# ls -lart /dev/mpath/
# ls -lart /dev/disk/by-path/

I need all the requested info from your new box where you want to create the same layout. It seems that you have given the info from old box.
Because date in listing shows that these were created on 7 Oct and If the LUNs are scanned in this month (today or yesterday) then it should show the month as March not the Oct.

Yes these information is from old box..
I haven't contacted the storage team yet to provide me with the lun for new box, as i didn't know the size of the luns and how the lun is configured in old box
from your response i have got an understanding of how this lun is configured ,i can ask the storage team to provide me the lun that will be on monday.
I have few more question from the old box.
