I've inherited a VM image so not 100% sure how initial disks were set up.I've attempted to extend my image by 10Gb following some basic instructions & adding a partition but can't seem to commit the final change for re-size using resize2fs or xfs_growfs to get this space.There wasn't an initial Volume group.Pretty much followed this thread set:https://ma.ttias.be/increase-a-vmware-disk-size-vmdk-formatted-as-linux-lvm-without-rebooting/https://ma.ttias.be/increase-expand-xfs-filesystem-in-red-hat-rhel-7-cento7/I'm probably missing something - help appreciated! - extracts listed:>resize2fs /dev/VolGroup1/lv1resize2fs: Bad magic number in super-block while trying to open    /dev/VolGroup1/lv1Couldn't find valid filesystem superblock.>fdisk -lDisk /dev/sda: 32.2 GB, 32212254720 bytes, 62914560 sectorsUnits = sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk label type: dosDisk identifier: 0x0009cd2bDevice Boot      Start         End      Blocks   Id  System/dev/sda1   *        2048      616447      307200   83  Linux/dev/sda2          616448     4810751     2097152   82  Linux swap / Solaris/dev/sda3         4810752    41943039    18566144   83  Linux/dev/sda4        41943040    62914559    10485760   8e  Linux LVMDisk /dev/mapper/docker-8:3-101670494-pool: 107.4 GB, 107374182400 bytes,             209715200 sectorsUnits = sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 65536 bytes / 65536 bytesDisk /dev/mapper/VolGroup1-lv1: 10.7 GB, 10733223936 bytes, 20963328 sectorsUnits = sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytes>pvdisplay--- Physical volume ---  PV Name               /dev/sda4  VG Name               VolGroup1  PV Size               10.00 GiB / not usable 4.00 MiB  Allocatable           yes (but full)  PE Size               4.00 MiB  Total PE              2559  Free PE               0  Allocated PE          2559  PV UUID               cKHlxe-rqVT-XsnU-Brlv-yV6t-JhYJ-u48YGx> vgdisplay--- Volume group ---  VG Name               VolGroup1  System ID               Format                lvm2  Metadata Areas        1  Metadata Sequence No  3  VG Access             read/write  VG Status             resizable  MAX LV                0  Cur LV                1  Open LV               0  Max PV                0  Cur PV                1  Act PV                1  VG Size               10.00 GiB  PE Size               4.00 MiB  Total PE              2559  Alloc PE / Size       2559 / 10.00 GiB  Free  PE / Size       0 / 0     VG UUID               q4ntG1-r2Mf-Bvme-2djz-g42f-8J4s-eyB2Sd> lvdisplay --- Logical volume ---   LV Path                /dev/VolGroup1/lv1   LV Name                lv1   VG Name                VolGroup1   LV UUID                qslLy5-C7vv-DSMR-m9Lr-zHFB-8IXf-g51jch   LV Write Access        read/write   LV Creation host, time localhost.localdomain, 2015-12-05 09:51:18 -0800   LV Status              available   # open                 0   LV Size                10.00 GiB   Current LE             2559   Segments               1   Allocation             inherit   Read ahead sectors     auto   - currently set to     8192   Block device           253:1> df -kFilesystem     1K-blocks     Used Available Use% Mounted on/dev/sda3       18555904 18098240    457664  98% /devtmpfs         1788224        0   1788224   0% /devtmpfs            1797156      148   1797008   1% /dev/shmtmpfs            1797156     9092   1788064   1% /runtmpfs            1797156        0   1797156   0% /sys/fs/cgroup/dev/sda1         303788   154352    149436  51% /boot/dev/sr0           54532    54532         0 100% /run/media/centos/CDROM
