Today I upgraded my system to 10.3-STABLE r319937 successfully. It's installed on UFS with GELI. When I double-click a VM in virtualbox, the system reboots because of a kernel panic. After autofsck, the login prompt shows, but the system reboots again while I input my login imformation and press Enter. I have to boot single user mode and run fsck manually, then login as root. Everything is fine, however I suddenly find all data in my home directory disappeared; that is to say, my home directory is empty. I think my data still exists on the disk and this is just the problem about filesystem, because: 1. The total size of my home directory is about 132GB before. When I check the output of "df -h" now, the value of "Used" is still about 132GB. 2. The operation of user login shouldn't cause a kernel panic, even though the home directory is empty. 3. "ls -a /home/fbsd" hasn't any output, but normally it should output . and .. at least. I try to use recoverdisk(1) to recover a file that I can remember its name. For example: # recoverdisk /home/fbsd/.zshrc .zshrc Bigsize = 1048576, medsize = 32768, minsize = 512 start size block-len state done remaining % done 0 4220 4220 0 4220 0 100.00000 Completed Although I checked this file and confirmed the recovery is successful, I can't recover all data by this way since it's impossible to remember all filenames. As far as I know, recoverdisk(1) doesn't support directory recovery like "recoverdisk <src_dir> <des_dir>". Should I try to use something like "recoverdisk /dev/<geli_node> <usbmnt_dir>" firstly? Any idea about this? Thanks!
