I was deploying a VM and I needed more space for \/.
\nSo first I turned off the machine and modified the machine.ovf file to increase de size of the hard disk:
\nFrom <\/p>\n
<Disk ovf:capacity="8589934592" ovf:diskId="vmdisk2" ovf:fileRef="file1"\u2026<\/pre>\nTo<\/p>\n
<Disk ovf:capacity="28589934592" ovf:diskId="vmdisk2" ovf:fileRef="file1"\u2026<\/pre>\nThen I started the VM to expand the fs
\nInitial situation (take a look at \/)<\/p>\n\r\nroot@machine:~# df -h\r\nFilesystem Size Used Avail Use% Mounted on\r\n\/dev\/dm-0 7.2G 5.7G 1.2G 84% \/\r\nudev 10M 0 10M 0% \/dev\r\ntmpfs 403M 5.5M 397M 2% \/run\r\ntmpfs 1006M 0 1006M 0% \/dev\/shm\r\ntmpfs 5.0M 0 5.0M 0% \/run\/lock\r\ntmpfs 1006M 0 1006M 0% \/sys\/fs\/cgroup\r\n\/dev\/sda1 236M 33M 191M 15% \/boot\r\n<\/pre>\nPhysical Volumes<\/p>\n

\nJust a last check:<\/p>\n\r\nroot@machine:~# pvscan\r\n PV \/dev\/sda5 VG debian-jessie-vg lvm2 [26.38 GiB \/ 18.62 GiB free]\r\n Total: 1 [26.38 GiB] \/ in use: 1 [26.38 GiB] \/ in no VG: 0 [0 ]\r\nroot@machine:~# lvdisplay\r\n --- Logical volume ---\r\n LV Path \/dev\/debian-jessie-vg\/root\r\n LV Name root\r\n VG Name debian-jessie-vg\r\n LV UUID OdIAov-a7qm-ThOR-58YP-D7FG-zq5n-r73dUq\r\n LV Write Access read\/write\r\n LV Creation host, time debian-jessie, 2015-04-27 10:42:28 +0200\r\n LV Status available\r\n # open 1\r\n LV Size 7.39 GiB\r\n Current LE 1892\r\n Segments 1\r\n Allocation inherit\r\n Read ahead sectors auto\r\n - currently set to 256\r\n Block device 254:0\r\n\r\n --- Logical volume ---\r\n LV Path \/dev\/debian-jessie-vg\/swap_1\r\n LV Name swap_1\r\n VG Name debian-jessie-vg\r\n LV UUID dS5vEu-w8LQ-uoZd-IGk8-cmaK-8tBQ-ZtSyvO\r\n LV Write Access read\/write\r\n LV Creation host, time debian-jessie, 2015-04-27 10:42:28 +0200\r\n LV Status available\r\n # open 2\r\n LV Size 376.00 MiB\r\n Current LE 94\r\n Segments 1\r\n Allocation inherit\r\n Read ahead sectors auto\r\n - currently set to 256\r\n Block device 254:1\r\n\r\n<\/pre>\nSo the path for my LV is \/dev\/debian-jessie-vg\/root<\/p>\n
And…<\/p>\n

So, let’s use them. I extend first the LV:<\/p>\n

\r\nroot@machine:~# resize2fs \/dev\/debian-jessie-vg\/root\r\nresize2fs ... (it does it all automatically)\r\n\r\n<\/pre>\nAnd that’s all!
