Hi, there are tons of RAID1 tutorials, but none of them deal with lvm. The problem is that I want to expand my current lvm partition over RAID1 rather than creating a new lvm partition after RAID1 is created.
My master harddrive has lvm partition. I'm wondering how to create a RAID1 image of... (1 Reply)

Hi guys.
I'm confused how LVM snapshots work. Here is what i understood:
1. we have a Logical Volume holding our data.
2. we make a snap shot of it with this command:
lvcreate -L 1000M -s -n backup /dev/vg01/lv013. mount the snap shot
4. take your backup
5. remove the snapshot --> in this... (3 Replies)

To create Physical Volumes for Volume groups (LVM) , the disk need to be partitioned to LVM type ie. 'Linux LVM' type . In fdisk , this can done by choosing 8e when prompted for partition type.
Since it is easy to script (non-interactive), I use parted command rather than... (1 Reply)
I am running Ubuntu 16.04 on a HP laptop with a core I3 processor. I am trying to run mariaDB and do hot backups to disk.

dumpe2fs
DUMPE2FS(8) System Manager's Manual DUMPE2FS(8)NAME
dumpe2fs - dump ext2/ext3/ext4 filesystem information
SYNOPSIS
dumpe2fs [ -bfghixV ] [ -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).
-g display the group descriptor information in a machine readable colon-separated value format. The fields displayed are the group
number; the number of the first block in the group; the superblock location (or -1 if not present); the range of blocks used by the
group descriptors (or -1 if not present); the block bitmap location; the inode bitmap location; and the range of blocks used by the
inode table.
-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.
