Sorry for my poor English, I hope you will understand me.
A month ago I set up a Ubuntu server with a 500GB HDD, while installing the system I created regular, non-LVM, partitions - here's their layout.
root@skysquad:~# fdisk -l Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x000c9f61 Device Boot Start End Blocks Id System /dev/sda1 * 1 10942 87891583+ 83 Linux /dev/sda2 10943 60801 400492417+ 5 Extended /dev/sda5 12159 60801 390724866 83 Linux /dev/sda6 10943 12158 9767457 82 Linux swap / Solaris Partition table entries are not in disk order
sda1 (90GB) for OS (ext4)
sda5 (~370GB) for /home (I will explain later) (ext4)
sda6 (10GB) for SWAP
Later I realised that when sda5 (385GB for /home) will be full I would like to increase its size by adding a new HDD, so I made sda5 an LVM partition like so;
root@skysquad:~# pvdisplay --- Physical volume --- PV Name /dev/sda5 VG Name vg1 PV Size 372.62 GB / not usable 3.25 MB Allocatable yes (but full) PE Size (KByte) 4096 Total PE 95391 Free PE 0 Allocated PE 95391 PV UUID lewQnp-NdvK-Ac0N-sCgE-NGOH-K2cX-WxJ2tL root@skysquad:~# vgdisplay --- Volume group --- VG Name vg1 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 1 Max PV 0 Cur PV 1 Act PV 1 VG Size 372.62 GB PE Size 4.00 MB Total PE 95391 Alloc PE / Size 95391 / 372.62 GB Free PE / Size 0 / 0 VG UUID yRkcP7-zvZ0-DjIR-xDWS-Ia6V-InSu-6Hwvpe root@skysquad:~# lvdisplay --- Logical volume --- LV Name /dev/vg1/home VG Name vg1 LV UUID jXCi37-iWmp-xVd7-9TsL-56pg-6x9m-73flLT LV Write Access read/write LV Status available # open 1 LV Size 372.62 GB Current LE 95391 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 252:0
Now my sda5 (LVM) is full (see below), but my wallet is not, and I can't just buy another HDD.
root@skysquad:~# df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda1 86511612 3829536 78287500 5% / tmpfs 1677788 0 1677788 0% /lib/init/rw varrun 1677788 520 1677268 1% /var/run varlock 1677788 0 1677788 0% /var/lock udev 1677788 144 1677644 1% /dev tmpfs 1677788 84 1677704 1% /dev/shm lrm 1677788 2192 1675596 1% /lib/modules/2.6.28-15-generic/volatile /dev/mapper/vg1-home 384590900 332537772 32517052 92% /home
As you can see I'm only using 5% of / (sda1) (I don't know what I had in mind when I was setting 90GB for /).
So finally my question - is there any SAFE way to resize non-LVM partitions (i.e. decrease sda1 size by 60GB, from 90GB to 30GB, and increase sda5 with this 60GB from ~370GB to ~430GB) and then increase LVM at sda5 with those 60GB?
