similar to: LVM - pvmove and multiple servers

I've replaced disks in a hardware RAID 1 with larger disks and enlarged the array. Now I have to find a way to tell LVM about the extra space. It seems there are two ways: 1. delete partition with fdisk and recreate a larger one. This is obviously a bit tricky if you do not want to lose data, I haven't investigated further yet. 2. create another partition on the disk, pvcreate another

I read your version of the procedure and it looks like you want to skip the pvmove. That's fine, but it means more downtime (an unreliable estimate is one minuted per GB). In that case, you don't even need the snapshot. You won't need a point in time

Hi all I have a remote server (i.e SSH access only) which was incorrectly partitioned and I urgently need to get it up and running. It's got a 500GB HDD, but the PV is only 10GB big, so I can't add more LV's to to. P.S. This is on LVM, btw. [root at nd11176 ~]# fdisk -l /dev/sda Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders

What's the easiest way to transition to a larger HD when using LVM2? I'm running Centos 4.4. I'm going from a 20gb HD to a 40gb HD. I've already DD'd it to the 40gb HD. So now I have 20gb of unused space. Ideally, I'd like to make it one big physical space for the logical space instead of making another physical partition to expand the logical. Here is what I have now

Hi, I'm needing to expand a LUN on my EMC CX4-120 SAN. (Well I already had done it). On this LUN I had a PV of a cLVM VG. Know I need to run pvresize on it. Has anybody done this on a cLVM PV ? I'm trying to rescan the devices, but I can't "see" the new size. And, googling on it I can only find RHEL5.2 responses. Thanks in advance,

Dear All, I am in desperate need for LVM data rescue for my server. I have an VG call vg_hosting consisting of 4 PVs each contained in a separate hard drive (/dev/sda1, /dev/sdb1, /dev/sdc1, and /dev/sdd1). And this LV: lv_home was created to use all the space of the 4 PVs. Right now, the third hard drive is damaged; and therefore the third PV (/dev/sdc1) cannot be accessed anymore. I would like

Dear James, Thank you for being quick to help. Yes, I could see all of them: # vgs # lvs # pvs Regards, Khem On Sat, February 28, 2015 7:37 am, James A.

Are there any ways to improve/manage the speed of pvmove? Man doesn't show any documented switches for priority scheduling. Iostat shows the system way underutilized even though the lv whose pe's are being migrated is continuously being written (slowly) to. Thanks! jlc

Dear All, I plan to replace an error disk that is part of an LV. from LVM how-to it could be done with using pvmove to move all PE from old disk to new disk.But the howto also said that pvmove is slow. Anyone has experience using pvmove on 2TB disk? Is it possible to make all PE on the old disk empty so I don't have to do pvmove (assuming that I can make a free space >= 2TB). Thank you in

Hi, I was wondering if there was a way to extend (ie: grow) a PV that is part of a Volume Group? I currently have a partition on my HD that is being used as a PV for my Volume Group, but would like to make it larger. I have the space on my drive to extend my partition, but using standard tools (ex: gparted, Partition Magic, etc) would likely end up corrupting the data on in the Logical Volumes

Hi. I have some narrow questions and a larger one. If I make an existinig LVM VG a storage pool, can I use some of the LV's for libvirt and some for the host? Or does the VG needed to be completely dedicated to virtualization? Assuming mixed use is possible, is it possible to do an LVM snapshot of an LV in use for a VM? The snapshot would have to be initiated and used on the host, I

Hi guys, I need to move an lvm based domU from one dom0 to another dom0. How do you guys do ths? xm save/restore doesnt have the option to specify lvm target as the storage.

Hello everybody, I am in the process of setting up a really cool xen serverfarm. Backend storage will be an LVMed AoE-device on top of DRBD. The goal is to have the backend storage completely redundant. Picture: |RAID| |RAID| |DRBD1| <----> |DRBD2| \ / |VMAC| | AoE | |global LVM VG| / | \ |Dom0a| |Dom0b| |Dom0c| | |

Dear all, I have a 4,1TB Logical volume consist of four disks with size of 2TB, 1TB, 1TB, and 500GB. The LV currently full. I plan to change the 1Tb disks and 500Gb disks. I plan to remove one 1TB disk or the 500GB so that I can replace it with 2TB disk. most LVM tutorial ask to use pvmove to move phisical extent to the new disk. The problem is that I have no SATA port left so that I can't

Hello, I have a CentOS VM with only one disk on a Xenserver. The disk has 2 partitions: /dev/xvda1 -> /boot /dev/xvda2 -> a physical volume for LVM I added 5GB to this disk via Xencenter to extend /dev/xvda2. Usually I just have to do "pvresize /dev/xvda" to have the additional space added to the disk. But for some reason it does not work for this disk. [root ~]# pvresize

I should have added the output of pvs: [root ~]# pvs PV VG Fmt Attr PSize PFree /dev/xvda2 cl_vm731611 lvm2 a-- 9.00g 0 PFree still show 0. It should show 5g. Also: [root ~]# pvdisplay /dev/xvda2 --- Physical volume --- PV Name /dev/xvda2 VG Name cl_vm731611 PV Size 9.00 GiB / not usable 2.00 MiB Allocatable

Hey everyone, Is anybody aware of a /true/ active/active multi-head and multi-target clustered iSCSI daemon? IE: Server 1: Hostname: host1.test.com IP Address: 10.0.0.1 Server 2: Hostname: host2.test.com IP Address: 10.0.0.2 Then they would utilize a CLVM disk between them, let's call that VG "disk" and then directly map each LUN (1,2,3,4,etc) to LV's named 1,2,3,4,... and

Hi. I have a volume group (let's say) vg_data. It consists from /dev/sdd5 sdd6 sdd7 I added sdc5 Now I want to remove (free) sdd7 and you is to for RAID partition. What are the commands (ordered) I need to perform? I failed to find clear howto. vg-data has only one partition, total size is over 1TB, free space is about 500GB so

I have a workstation with two separate drives set up with LVM. I'm buying an LSI RAID controller to set up mirrored drives. I'd like to clone the existing drives over to the new mirrored drives somehow, but not sure the best way to do it. The original drives & their respective replacements are all identical in size (250GB + 1TB). I thought about using Clonezilla but wasn't sure
