I'm new to Linux and LVM coming from a BSD and Solaris background so I apologize up front if there are good docs for this that I'm missing. After googling around and going through the LVM Admin docs for CentOS I have a few questions about an issue I have.
Somehow either I did it out of stupidity or the installer automagically installed LVM and included both drives I have on this server. It's configured as 1 Volume group and 1 huge drive so most of the docs on LVM I've seen don't jive. Here's my pvdisplay: --- Physical volume --- PV Name /dev/sda2 VG Name VolGroup00 PV Size 148.91 GB / not usable 4.15 MB Allocatable yes (but full) PE Size (KByte) 32768 Total PE 4765 Free PE 0 Allocated PE 4765 PV UUID DOv3Cl-LWoU-JG04-PT0P-VfIV-89p2-yrdnbp
--- Physical volume --- PV Name /dev/sdb1 VG Name VolGroup00 PV Size 149.05 GB / not usable 17.13 MB Allocatable NO PE Size (KByte) 32768 Total PE 4769 Free PE 0 Allocated PE 4769 PV UUID LK017x-dWzY-KIGL-kfOr-687Z-DgEn-YMfOw5
As you can see it seems like there's no room...but here's my df print: Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 288G 170G 104G 63% / /dev/sda1 99M 31M 64M 33% /boot tmpfs 315M 0 315M 0% /dev/shm /dev/sdc1 230G 134G 85G 62% /ext_drive
So I'm running out of room and wanting to move all data to my main drive so I can replace the 2nd drive with a bigger one. When I try a pvmove it states I have no room: pvmove -v /dev/sdb1 Finding volume group "VolGroup00" No extents available for allocation
So now I'm lost...how can I put all data on my 1st drive and unhook the 2nd from LVM to replace it ? Any assistance is greatly appreciated. I'm installing system-config-lvm hoping the GUI may help me as well.
