- Ubuntu 12,04
- 1 6TB physical volume (the one with data) [ext4]
- 1 13TB PV (no data... I think?) [ext4]
Here is the story...
- I created an ext4 on the 13TB PV, added the 13TB to the VG to make a 13TB volume group.
- Everything went fine and then I ran:
And to my surprise.. I couldn't resize past 16TB ! (crap! should have checked this first!).
So, nothing happened.. Now what I want to do is remove the 13TB PV from the VG and do something else with it... but I get the following error:

Hi Guys,
I have a raidz zpool that consists of four disks. 2x2TB, 1x1TB and 1x0.75TB.
Originally it was only 1x1TB, 3x0.75TB, and I had around 1.7TB of storage capacity. I've just switched out two of the 0.75TB disks for the 2x2TB ones. I did this one at a time and now the resilvering is... (2 Replies)

dumpe2fs
DUMPE2FS(8) System Manager's Manual DUMPE2FS(8)NAME
dumpe2fs - dump ext2/ext3/ext4 filesystem information
SYNOPSIS
dumpe2fs [ -bfhixV ] [ -o superblock=superblock ] [ -o blocksize=blocksize ] device
DESCRIPTION
dumpe2fs prints the super block and blocks group information for the filesystem present on device.
Note: When used with a mounted filesystem, the printed information may be old or inconsistent.
OPTIONS -b print the blocks which are reserved as bad in the filesystem.
-o superblock=superblock
use the block superblock when examining the filesystem. This option is not usually needed except by a filesystem wizard who is
examining the remains of a very badly corrupted filesystem.
-o blocksize=blocksize
use blocks of blocksize bytes when examining the filesystem. This option is not usually needed except by a filesystem wizard who is
examining the remains of a very badly corrupted filesystem.
-f force dumpe2fs to display a filesystem even though it may have some filesystem feature flags which dumpe2fs may not understand (and
which can cause some of dumpe2fs's display to be suspect).
-h only display the superblock information and not any of the block group descriptor detail information.
-i display the filesystem data from an image file created by e2image, using device as the pathname to the image file.
-x print the detailed group information block numbers in hexadecimal format
-V print the version number of dumpe2fs and exit.
BUGS
You need to know the physical filesystem structure to understand the output.
