If this problem persists, please make sure the content databases are available and have sufficient free space" I performed the following steps: take the backup using stsadm restore using the stsadm restore. for troubleshooting i did the following stuff. I restore it with overwrite switch, no luck. I checked the plenty of space available on all drives and even on the Database server. i try to restore it in a newly created content db but its failed with same error. i try to restore it with other farms its worked Please help me how can i get back that site, its production issue. thanks -wsSharePoint administrator, MCTS,MCITP
