I needed to add more storage to my CentOS6 machine for my remote system backups. I decided to allocate a completely new volume group and volume to facilitate this need. Here are the steps I used to create the volume:<\/p>\n
The new disk was added via vSphere, since this a VM. I determined the correct device file by looking to the dmesg output.<\/p>\n
Initialize the whole disk using pvcreate.
\n# pvcreate \/dev\/sde<\/p>\n
For partitions, use pvcreate \/dev\/sde[x].<\/p>\n
Create a volume group
\n# vgcreate vg_vmlinux01_backup \/dev\/sde<\/p>\n
To add multiple disks or partions, use vgcreate volume_group_name \/dev\/sdx \/dev\/sdy …<\/p>\n
Activate the volume group:
\n# vgchange -a y vg_vmlinux01_backup<\/p>\n
Create logical volume
\nThis will allocate all remaining available space to the volume. You can use -L to specify a particular size. Not needed in my case.
\n# lvcreate -l 100%FREE -n lv_rmbackup vg_vmlinux01_backup<\/p>\n
Write the filesystem with the desired label.
\n# mkfs -t ext4 -j -L \/rmbackup \/dev\/vg_vmlinux01_backup\/lv_rmbackup<\/p>\n
If you need to create the filesystem with more than the default number of inodes:
\n# mkfs -t ext4 -j -N 20000000 -L \/rmbackup \/dev\/vg_vmlinux01_backup\/lv_rmbackup<\/p>\n
Modify the \/etc\/fstab:
\n# vi \/etc\/fstab
\n…
\nLABEL=\/rmbackup \/rmbackup ext4 defaults 1 0
\n…<\/p>\n
Mount it:
\n# mount \/rmbackup<\/p>\n","protected":false},"excerpt":{"rendered":"
