I'm trying to extend a logical volume and I'm doing as follow:
1- Run `fdisk -l` command and this is the output:
Disk /dev/sda: 85.9 GB, 85899345920 bytes 255 heads, 63 sectors/track,
10443 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes I/O size
(minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00054fc6
Device Boot Start End Blocks Id System
/dev/sda1 * 1 64 512000 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 64 10444 83371008 8e Linux LVM
Disk /dev/mapper/vg_devserver-lv_swap: 4194 MB, 4194304000 bytes 255
heads, 63 sectors/track, 509 cylinders Units = cylinders of 16065 *
512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512
bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk
identifier: 0x00000000
Disk /dev/mapper/vg_devserver-lv_root: 27.5 GB, 27523022848 bytes 255
heads, 63 sectors/track, 3346 cylinders Units = cylinders of 16065 *
512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512
bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk
identifier: 0x00000000
2- Run `fdisk /dev/sda`and print partition using `p`:
Disk /dev/sda: 85.9 GB, 85899345920 bytes 255 heads, 63 sectors/track,
10443 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes I/O size
(minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00054fc6
Device Boot Start End Blocks Id System
/dev/sda1 * 1 64 512000 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 64 10444 83371008 8e Linux LVM
Try to create the partition by running:
Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 3
No free sectors available
I also check the free available space using vgdisplay and watching the Free
PE / Size part near the end and seems like I've free space available (Free
PE / Size 7670 / 29.96 GiB) so I tried to extend the LV by using the
command:lvextend -L+29G /dev/vg_devserver/lv_root but I got some errors and
don't know where to go from here. The first error I see at console is
this /dev/root:
read failed after 0 of 4096 at 27522957312: Input/output error /dev/root:
read failed after 0 of 4096 at 27523014656: Input/output error Couldn't
find device with uuid vSbuSJ-o1Kh-N3ur-JYkM-Ktr4-WEO2-JWe2wS. Cannot change
VG vg_devserver while PVs are missing. Consider vgreduce --removemissing.
Then following the suggestion from the previous command results I run this
other command vgreduce --removemissing vg_devserver but again got this
error: WARNING: Partial LV lv_root needs to be repaired or removed. There
are still partial LVs in VG vg_devserver. To remove them unconditionally
use: vgreduce --removemissing --force. Proceeding to remove empty missing
PVs. so I change the command to the one suggested but once again another
message Removing partial LV lv_root. Logical volume vg_devserver/lv_root
contains a filesystem in use. so at this point I don't know what else to
do,can any give me some ideas or help?
Don't kill me if is something basic I'm not a Linux Admin or a Linux
Advanced User just a developer trying to setup their development
environment. How I can get this done? What I'm doing wrong?
I'm following [this][1] guide because my filesytem is Ext4. Also [this][2]
is helpful too but applies to Ext3 only
