Hi Alasdair,
First, thanks for your fast answer. I added the "device-mapper" type
but it is still not working. Example:
jupiter:~# ls -l /dev/mapper
total 0
crw------- 1 root root 10, 63 Nov 3 23:25 control
brw-r----- 1 root root 253, 4 Nov 7 13:00 crypt10
brw-r----- 1 root root 253, 5 Nov 7 13:02 crypt11
brw-r----- 1 root root 253, 6 Nov 7 13:02 crypt12
brw-r----- 1 root root 253, 7 Nov 7 13:02 crypt13
brw-r----- 1 root root 253, 8 Nov 7 13:03 crypt14
brw-r----- 1 root root 253, 9 Nov 7 13:03 crypt15
brw------- 1 root root 253, 3 Nov 5 22:14 rs-home
brw------- 1 root root 253, 0 Nov 5 22:14 rs-root
brw------- 1 root root 253, 1 Nov 5 22:14 rs-usr
brw------- 1 root root 253, 2 Nov 5 22:14 rs-var
jupiter:~# vgscan
Reading all physical volumes. This may take a while...
Found volume group "rs" using metadata type lvm1
jupiter:~# grep crypt /etc/lvm/.cache
jupiter:~#
So grep shows that no crypt devices were found :(. I've attached my
current lvm.conf file. Please, if you were so kind to have a look...
I've set-up lvm1 mode ('cause I read that it is more stable than lvm2)
but I also did some tests with lvm2 and vgscan didn't detect my crypt
(=mapper) devices either. I've also set up a strict filter (although
I've also tried with less-restrictive ones with no success).
Saludos,
--Roman
