I recently upgraded my Eee 901 from Ubuntu 9.04 to 10.04 and although I've loved 10.04 so far (except for the theme and buttons-on-left issue) this install really didn't go very well.
As I mentioned in an earlier thread, the Eee 901 has two solid state disks, a 4G one for OS, and a 16G one for /home. I have my 16G disk encrypted with dm-crypt, without LUKS, and in Jaunty I just made a file called /etc/crypttab and put the following line in it:
crypthome /dev/sdb1 none cipher=aes,size=256
That worked great in Jaunty: on boot it asked me for the password and mounted it, then mounted home. All this was done automatically from the /etc/init.d/cryptdisks script. If I needed to remap it I could just call that init script with the restart argument and it would do so.
Now in Lucid the init script seems to have no effect. I put the /etc/crypttab file there just like it was previously, but when I call that script nothing happens. No error messages or anything, and I have no idea where log messages would be if they were enabled.
Running the script manually doesn't work either. The only way I can actually mount the encrypted volume is using the cryptsetup command directly, which is not exactly a feasible long-term solution.
Anybody have any experience with this? Last time I got similar results--it pretended it didn't exist until I added the size=256,cipher=aes and after that it worked fine. I've added the hash=sha1 option, changing the cipher= option to aes-cbc-plain (which is what 'cryptsetup status crypthome' reports) and I've also tried adding the loud option, but none of those things seem to do anything. The man page for crypttab hasn't been much help. Anybody have any suggestions?
