similar to: Centos7 - remove /home and expand / after install?

Hi list. I''m running Xen 4.0.1 on Debian. I''m trying to live resize a block device : - I have a arbitrary block device in my dom0 (/dev/mapper/vm-vol42). - I start a PV domain with that device as a disk (disk = [''phy:/dev/mapper/vm-vol42,xvda,w'']). - I resize vm-vol42 in the dom0 (adding size only) - the dom0 sees the device''s new size. -

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'm getting a large number of messages like this under CentOS-7. Is that normal? Or do I need to take some action (maybe reducing verbosity level)? ------------------------------------- Jul 16 17:43:01 localhost-002 systemd: Starting Session 54 of user tim.

I am testing some kickstarts on ESXi virtual machine with pair of 16GB disks. Partitioning is lvm over raid. If i am using "logvol --grow i get "ValueError: not enough free space in volume group" Only workaround i can find is to add --maxsize=XXX where XXX is at least 640MB less than available. (10 extents or 320Mb per created logical volume) Following snippet is failing with

We have a machine that's a distro mirror - a *lot* of data, not just CentOS. We had the data on /dev/sdc. I added another drive, /dev/sdd, and created that as /dev/md4, with --missing, made an ext4 filesystem on it, and rsync'd everything from /dev/sdc. Note that we did this on *raw*, unpartitioned drives (not my idea). I then umounted /dev/sdc, and mounted /dev/md4, and it looked fine; I

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 trouble finding definitive information about this. I am considering the use of SME 7.5.1 (centOS based) for my server needs, but I do want to use ZFS and I thus far I have only found information about the ZFS-Fuse implementation and unclear hints that there is another way. Phoronix reported that http://kqinfotech.com/ would release some form of ZFS for the kernel but I have found nothing.

I'm having some difficulty finding a method to shrink my /home to expand my /.? They both correspond to LVMs.? It is my understanding that one cannot shrink a xfs filesystem.? One must back it up (xfsdump), remove (lvremove) redefine it and then restore it back (xfsrestore). Okay, I'm running into a problem where /home? needs to be "unused".? If tried going in to

I am trying to use: ocfs-support-1.0.10-1 ocfs-2.4.21-EL-smp-1.0.11-1 ocfs-tools-1.0.10-1 with RedHat AS 3.0, 2-node cluster with shared SCSI. 2 dell 1650s, dual CPUs, PERC 3/DC cards chained to a PowerVault 220S. I am using lvm, and here is my layout: [root@cluster1 archive]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 32G 5.1G 25G

Side note: In CentOS-6, I noticed a new option in lvresize / lvextend: -r, --resizefs Resize underlying filesystem together with the logical volume using fsadm(8). Nice. Two steps (lvresize and resize2fs) can now be combined into one! Works great. But that has nothing to do with my question, just thought I'd share the discovery. == Anyway, here's

I've used LVM on servers with hot-swap drives to migrate to new storage without downtime a number of times. Add new drives to the system, configure RAID (software or

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, I did df -h on my CentOS 6.4 machine. $ df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_ysg-lv_root 47G 8.8G 36G 20% / tmpfs 948M 372K 947M 1% /dev/shm /dev/sda1 485M 62M 398M 14% /boot /dev/mapper/vg_ysg-lv_home 4.6G 2.7G 1.7G 63% /home What I don't understand is why

I have a Xen LVM based VM with two partitions: /dev/VolGroup00/vm01p1 /dev/VolGroup00/vm01p2 p2 is about 50GB, I gave it's LVM an extra 30 or so using lvextend. How can I extend the partition to fill my free space and the filesystem? I don't mind offline, if I can get Xen to boot off an alternative media.
