activating lv 'data/data' failed: check of pool data/data failed (status:1)

[lsampaio]

After an improper shutdown, the Proxmox server turned on normally, but presented the following message when I tried to start a virtual machine:
"task error: activating lv 'data/data' failed: check of pool data/data failed (status:1). manual repair required!"
How should I proceed?
