similar to: Resizing disks for VMs

I came across an old post comment yesterday (from http://echenh.blogspot.com/2010/04/how-to-extend-lvm-on-vmware-guest-os.html ) discussing the "hack" of LVM on Linux VM guests and whether it's better not to use it to simplify disk management. I've re-posted the comment below, does it sound reasonable? Is it better to not use LVM on Linux VM guests? --Russell

Greetings - I had a logical volume that was running out of space on a virtual machine. I successfully expanded the LV using lvextend, and lvdisplay shows that it has been expanded. Then I went to expand the filesystem to fill the new space (# resize2fs -p /dev/vde1) and I get the results that the filesystem is already xx blocks long, nothing to do. If I do a # df -h, I can see that the

I have a laptop that I put centos 7 on and I started out with a 30gig partition.? I resized the other part of the disk to allow more space for centos.? I then created an unformated partition in the available space,? ran pvcreate /dev/sda4 vgextend lvname /dev/sda4 lvextend -L 184.46G /dev/lvname/root but when I run: sudo resize2fs /dev/lvname/root I get: resize2fs: Bad magic

I now how to expand a LVM by creating a new drive as described here: http://lists.centos.org/pipermail/centos/2007-February/032664.html, the steps are: # pvcreate /dev/sda3 # vgextend VolGroup00 /dev/sda3 Now, I want to know how to expand a LVM without create /dev/sda3? Suppose I have 2 GB free (unpartitioned) and LVM use /dev/sda2 (8 GB). How to make /dev/sda2 become 10 GB? Then resize LVM

Hello list! (resending, it seems the previous mail didn''t make it to the list) At some point Xen supported block-reconfigure to resize domU disks on the fly.. This is not working atm/anymore? Discussion about the subject.. (in the end of the thread): http://lists.xensource.com/archives/html/xen-users/2008-04/msg00246.html Support for online resizing Linux SCSI disks was accepted

Hi all! I've got a VM at work running C6 on HyperV (no, its not my fault, that's what the company uses. I'd rather gag myself than own one of th ose things.) I ran out of disk space in the VM, so the admin enlarged the virtual disk. but now I realize I don't know how to enlarge the partition and its filesystem. I'll be googling, but in case I miss it, it'd be great if

Here's the situation. I have a dual boot machine - originally had Red Hat and Windows 2000 Pro. The NTFS partition never did seem to 'get along' with the Adaptec 2400A caching RAID controller. Linux always seemed to like the I2O drivers. I went from RH Enterprise to now running Centos 5.5. Works great! I really don't want the 200 gigs worth of NTFS. Can't I just run

Dear CentOS-Community, we have a server with four hard drives that are configured as raid10 (/dev/sda). Now, /home and /root are almost full. Therefore, we decided to buy four additional hard drives that should configured also as raid 10 (/dev/sdb). I want to use LVM to extend disk space for root and home. My (successful) test procedure in a virtual environment looks like this: 1. devide

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,

Hi, I'm thinking about how to go about migrating our Xen VMs to KVM. Migrating the configuraton should be easy using the virsh dumpxml/define commands but what is the best way to transfer the (logical volume based) images without too much downtime for the guest system? Can rsync operate on logical volumes? If so I could potentially use "dd" to transfer an initial copy of the

Are folks in the Centos community succesfully using device-mapper-multipath? I am looking to deploy it for error handling on our iSCSI setup but there seems to be little traffic about this package on the Centos forums, as far as I can tell, and there seems to be a number of small issues based on my reading the dm-multipath developer lists and related resources. -geoff Geoff Galitz Blankenheim

Hi, We have some problems with Xen 4.0.1 and resinzing of lvm volumes. When I resize a lvm volume with "lvresize -L+50G -n /dev/data/windows-data" the Windows Dom U don''t scan the new size of the lvm volume. The only way to see the extend is to halt and create the DomU We have try with sign and unsigned drivers gplpv, with Windows 2008 and Windows 2003 server :

Hi, This is my current config: /dev/md0 -> 200 MB -> sda1 + sdd1 -> /boot /dev/md1 -> 36 GB -> sda2 + sdd2 -> form VolGroup00 with md2 /dev/md2 -> 18 GB -> sdb1 + sde1 -> form VolGroup00 with md1 sda,sdd -> 36 GB 10k SCSI HDDs sdb,sde -> 18 GB 10k SCSI HDDs I have added 2 36 GB 10K SCSI drives in it, they are detected as sdc and sdf. What should I do if I

Not a centos specific question here, but if anyone can save me from shooting myself in the foot would appreciate any pointers.... I have an older centos 4.7 box that I recently replaced with a newer one running centos 5.3. I'd like to add the hard disk from the older one to the newer one before I scrap it for good. I don't care about the data on it, would just like the extra drive

Hi! Say I export an LVM logical volume from dom0 as /dev/xvda to the domU: disk = [ ''phy:xenimages/stan,xvda,w'' ] No I can lvresize xenimages/stan in dom0, but the domU stays ignorant of this change. How could I propagate the resize to the domU without rebooting or temporarily breaking its connection to /dev/xvda? Sort of a SCSI rescan, perhaps? -- Thanks, Feri.

I have a database server that is running out of space. All my databases are being stored in a 80G /opt partition. Because I'm using LVM, wouldn't I be able to pop the HDDs (a h/w raid volume) in, add it to the LVM, and resize my ext3 /opt partition? Everything that I've been reading says this is possible, but I'm not sure. Has anyone done this and are there any pitfalls to

Hi all, I have a disk of 146Gb in a machine intended to have mainly mysql database, apache and some web data.? I didn't use LVM for / and /boot during the installtion Could I extend? easily in the future the /var partition? when I add another disk? ?Filesystem??????????? Size? Used Avail Use% Mounted on /dev/cciss/c0d0p6????? 23G? 432M?? 22G?? 2% / /dev/mapper/VolGroup00-LogVol00
