I needed to forward this to the listserv. Also, on the same note, I discovered another odd behavior:
Several VMs have been deleted, their state is DONE, and I manually removed their folders. However, when I issue a 'show' command to view information for VMs that have transitioned to the DONE state, a folder is created for them. What's odd about this behavior, is that it only occurs the first time I issue the 'show' command. Issuing that command a second time does not re-create the folder. oneadmin@opennebula-server:~$ ls auth config images oneacct.db one.db onequota.db remotes oneadmin@opennebula-server:~$ onevm show 4 VIRTUAL MACHINE 4 INFORMATION ID : 4 NAME : vm-example USER : oneadmin GROUP : oneadmin STATE : DONE LCM_STATE : LCM_INIT START TIME : 12/14 14:05:47 END TIME : 12/14 15:39:16 DEPLOY ID : VIRTUAL MACHINE MONITORING NET_TX : 0 NET_RX : 0 USED MEMORY : 0 USED CPU : 0 VIRTUAL MACHINE TEMPLATE ... VMID=4 oneadmin@opennebula-server:~$ ls 4 auth config images oneacct.db one.db onequota.db remotes oneadmin@opennebula-server:~$ rm -r 4 oneadmin@opennebula-server:~$ ls auth config images oneacct.db one.db onequota.db remotes oneadmin@opennebula-server:~$ onevm show 4 VIRTUAL MACHINE 4 INFORMATION ID : 4 NAME : vm-example USER : oneadmin GROUP : oneadmin STATE : DONE LCM_STATE : LCM_INIT START TIME : 12/14 14:05:47 END TIME : 12/14 15:39:16 DEPLOY ID : VIRTUAL MACHINE MONITORING NET_TX : 0 NET_RX : 0 USED MEMORY : 0 USED CPU : 0 VIRTUAL MACHINE TEMPLATE ... VMID=4 oneadmin@opennebula-server:~$ ls auth config images oneacct.db one.db onequota.db remotes This makes the clean-up scripts potentially worthless since VMs within the database can cause changes to content within the file system, and no hook can resolve that. For my network policy, a simple clean-up hook is sufficient to remove files and folders that will no longer be needed. However, in the future, some method to purge even the database would be nice.
