Is is possible to extend physical volume disk space from one to another?

Could I get 50GB from /dev/sdb1 and add it to /dev/sda1 ???
extend the size of a LVM2 volume group over the remaining free space available on a physical volume. My linux box is a Ubuntu Karmic 9.10 64bit, the 60GB hard disk has 2 win partition for about 19GB, a 1.5GB ext3 boot partition and finally a 36GB LVM partition (/dev/sda4) on which I created a volume group (volgrp) smaller 10GB than the 36GB physical volume (/dev/sda4). What I want now is to extend the size of volume group up to the end of physical volume. I tried to use the "vgextend volgrp /dev/sda4" but system answers me
with following output:
me@pc:~> sudo vgextend volgrp /dev/sda4
Physical volume '/dev/sda4' is already in volume group 'volgrp'
Unable to add physical volume '/dev/sda4' to volume group 'volgrp'.
Here the output of fdisk command:
me@pc:~> sudo fdisk -l
Disk /dev/sda: 60.0 GB, 60011642880 bytes

so i have f12 installed on my hd with lvm using the whole extent of the HD , i want to reduce it so i can dual boot it with a windows system, i managed to reduce the logical volume to free some space, but i cant seem to reduce the physical volume, is this possible and how ?

My problem is that one of my disks died, and I have to send it back for a warranty replacement. However, the disk is dead, and I can't zero it out. I'm just trying to assess how difficult it would be (or at least how likely it would be) for a tech that's checking out the disk to get at the data.
View 4 Replies View RelatedI plan to install a server using LVM. I thought a partition schema where /boot would be in an ext4 partition while / /usr /var /home and /opt would be in the LVM. My question is: if I'm putting / into the LVM, is it necessary to divide /usr /var /home and /opt into different logical volumes? If I divide them, would it become harder to maintain when new disk space has to be added to the volume group?
View 7 Replies View RelatedI've added a new LUN to my Centos 5.2 server using Powerpath and have added it to an ext3 logical volume. I extended the logical volume using lvextend and the new space shows up correctly in lvdisplay. What I'm having problems with is getting Centos to see the new disk space (df -h shows 500GB, not 600GB as expected). I've tried running a resize2fs on the new volume but it tells me that "the filesystem is already n blocks long. Nothing to do". Does any one know where I'm going wrong? If possible I'd like to sort this without a reboot.

I can see that it is extended from the LVM GUI (System - Admin - LVM). However, when I download anything, the system says I am still at 99% capacity.
Code:
[root@localhost /]# fdisk -l

I have a system with a single disk that is partitioned as below:
1) hda
hda1 - boot partition - 0.3GB
hda2 - System - 15.7GB
There are 2 volumes on single group. The boot partion is a physical volume and the system is a logical volume. The disk has more room up to 40GB. How can I extend the logical volume. Tried system-config-lvm, but it does not gives the option.
I'm running debian and used mdadm to setup up a raid 6 array with 4x1TB drives with roughly 1.86TB's available with lvm. Then I added 4x1TB drives to the array. So now I have an 8 drive raid 6 array with 5.+TB's available, the array sees all available space. The question is how do I extend the volume group so that it uses the whole raid and not just half of it. As of right now the volume group is only 1.86TB's.

I've got a question on free disk space. I'm currently running CentOS 5.5 on in Xenserver virtual environment. We've had an issue with disk space. My question is as follows: - from a ssh connection i run df -h this gives the value of 90% used leaving me with 9GB. If I use system monitor via a VNC connection the free disk space value is 20GB free on the same volume. Which one is correct? I do use SNMP to monitor the same volume and should alert me when < 10% is free I know this works as I set the alert threshold to < 90% I get an alert.

I installed Fedora 14 onto the 4GB partition but I am running out of space. I have formatted the 8GB partition with ext4 but I am unsure the best way to create more space for the default installation. Can I extend my / partition onto the 8GB partition or possible move the /swap partition onto it?

I have a dual boot Ubuntu 10.04 and Vista laptop.
My Ubuntu partions /dev/sda4 extended, which contains a /dev/sda5 ext4 and a /dev/sda6 ntfs partition.
Vista is on /dev/sda2 ntfs. I would like to wipe vista out, turn off dual boot (if possible) and use the space taken by vista to extend my /dev/sda6 ntfs partition in ubuntu.
So I got a bad physical volume inisde my logical volume. I want to do this safely rather than tinkering around, how can I get the bad physical disk out and look at the data on the other 2 drives to see if I can save anything? Its just the standard fedora setup where it combines all the disks, nothing fancy.
I have the volume group activated as a partial, and now I just want to see the data on the other sections how could I mount that?
Let's assume I have a volume group (VG) with six physical volumens (PV) - sdb1, sdb2, sdb3, sdc1, sdc2, sdc3..I want to remove one of the PVs from the group in order to use its space elsewhere - how can I know if it's safe? How can I do that without losing data and without first "pvmove"ing it elsewhere?Reading a bit more, my guess is using the result of pvscan, but I thought I'd ask before removing keeping it safe as I'm not an LVM expert.

View 2 Replies View RelatedHow do I find the OID code for a physical volume.I managed to get it to work with our snmp monitoring software to alert me when disk space was < 10% but the computer which was running the SNMP monitoring died.For the life of me I can't remeber how I got it to work.I have 4 partitions 1 has 88% free /etc/mapper/volgroup002 has 21% free /boot3 nfsd 0 bytes4 sunrpc 0 bytesHere is a copy of the OID I'm using 1.3.6.1.2.1.25.2.3.1.5.1 I change the last number to resemble the drive but i'm testing using 8% and they each return an error drive space low which is what the VB script tells it to do. I know the script works as I use it on Windows Servers no problems.I do an SNMPWALK on the server and it validates the above OID with HOST-RESOURCES-MIB::hrStorageSize so I know thats valid.But thats where I'm stuck. What value should I see if I were to use this OID 1.3.6.1.2.1.25.2.3.1.6.1 which is for free disk space.

Maybe I'm missing something obvious but I do not see it listed in vgdisplay.
View 1 Replies View RelatedI have a 500GB hard disk, /dev/sda. On it, there is /dev/sda1 for /boot, /dev/sda2 for an LVM PV (physical volume), and /dev/sda3 for another /boot (multiple Linux distros, one boot partition for grub legacy, another for grub2). so the LVM2 partition, /dev/sda2, is taking up ~465GiB. I want to add another OS (non-Linux), so I resized the *lvm2 physical volume* to 320GiB, successfully, using pvresize.
However, I now need to resize the partition so the lvm2 physical volume only just fits on it, ie to 320GiB. My plan of action is to use gparted (the partition table is GUID, so fdisk won't work), to first delete the partition from the partition table, then re-add it but this time with a smaller value (~320GiB). The problem is that I need to know exactly how many MiB/cylinders the physical volume is taking up. So, I run:
Code:
root@sysresccd /root % pvdisplay
--- Physical volume ---
PV Name /dev/sda2
VG Name vg0
[code]....
What one of these values do I need to set the new lvm2 replacement partition to?
When I installed Ubuntu, I created an 52 gb encrypted partition which shows up in the disk utility, and in the window that opens when I click on the "home folder" icon. I get my normal windows partition, and under that the 52 GB LVM2 partition. But when I try to access it, I get this error.
Unable to mount 52 GB LVM2 Physical Volume - not a mountable file system
This is what fdisk -l shows

I have a 7.9 TB logical volume I've created from 8 1 TB RAID 0 devices. The volume is formatted with XFS so I can resize when ready. However, I think I want to do something that is not possible. I have 2.5 TB free on my logical volume. I'd like to shrink the volume down to be 6 TB by getting rid of 2 of the 1 TB devices in the physical volume. However pvmove seems to require free extents in order to work. Do I need to add 6 TB of storage, pvmove everything onto it, and then decommission the original 8 1 TB physical devices from the volume?

I've added a second drive to a system and I need to extend the lvm and the filesystem to the second disk. Is there a way to do this online with centos 5.5? I specifically need extending the actual ext3 filesystem which seems to be the trick part.
