# Block Storage
|
|
|
|
Manage block storage volumes and LVM.
|
|
|
|
## LVM Management
|
|
|
|
```bash
|
|
# Create physical volume
|
|
pvcreate /dev/sdb
|
|
|
|
# Create volume group
|
|
vgcreate data_vg /dev/sdb
|
|
|
|
# Create logical volume
|
|
lvcreate -L 50G -n app_lv data_vg
|
|
|
|
# Format and mount
|
|
mkfs.ext4 /dev/data_vg/app_lv
|
|
mount /dev/data_vg/app_lv /data
|
|
|
|
# Extend volume
|
|
lvextend -L +10G /dev/data_vg/app_lv
|
|
resize2fs /dev/data_vg/app_lv
|
|
```
|
|
|
|
## AWS EBS
|
|
|
|
```bash
|
|
# Create volume
|
|
aws ec2 create-volume \
|
|
--availability-zone us-east-1a \
|
|
--size 100 \
|
|
--volume-type gp3
|
|
|
|
# Attach to instance
|
|
aws ec2 attach-volume \
|
|
--volume-id vol-xxx \
|
|
--instance-id i-xxx \
|
|
--device /dev/xvdf
|
|
```
|
|
|
|
## Best Practices
|
|
|
|
- Use LVM for flexibility
|
|
- Implement RAID for redundancy
|
|
- Monitor disk I/O
|
|
- Regular disk health checks
