This thread prompted my curiosity so I decided to experiment. Regular readers may recall that I use LVM.. I already have a 13.1 system installed. I used YAst/partitioned to creazte a new LV size 5G, ext4, all defaults, encrypted, format. First time I didn't specify that it should be mounted. It was created OK # blkid /dev/vgmain/C111 /dev/vgmain/C111: UUID="8ed95c21-4b91-4b0c-9352-d3530ba5f8b1" TYPE="crypto_LUKS" I then tried mounting: # mount.crypt -v /dev/vgmain/C111 /mnt/disk NOTE: mount.crypt does not support utab (systems with no mtab or read-only mtab) yet. This means that you will temporarily need to call umount.crypt(8) rather than umount(8) to get crypto volumes unmounted. Password: (mtcrypt.c:526): keysize=0 trunc_keysize=32 (crypto-dmc.c:167): Using _dev_dm_22 as dmdevice name crypt_activate_by_passphrase: Device or resource busy Well, that wasn't happy. I flutzed around in this area for a bit with no success. I read tha man pages for crypttab and crypttabsetup, but didn't find them easy to understand. Eventualy I went back to Yast and tried to re-run but with a mount point specifcied. That produced a series of errors. So I deleted the LV and started over, this time specifying a mount point. This created an entry in /etc/fstab /dev/mapper/cr_mnt_crypt /mnt/crypt ext4 acl,user_xattr,nofail 0 2 Which isn't what I expected. I wonder what I'll get with another crypt'd LV? That was mounted for me /dev/mapper/cr_mnt_crypt on /mnt/crypt type ext4 \ (rw,relatime,data=ordered) Yes its there, # df -h /mnt/crypt Filesystem Size Used Avail Use% Mounted on /dev/mapper/cr_mnt_crypt 4.9G 11M 4.6G 1% /mnt/crypt It occurs to me that I can convert each and every one of my :Vs to an encrypted LV. Regular readers may also recall that I have many LVs, in fact I've factored out /srv, /opt, /usr/share and much stuff from /home My point here is that I can retrofit encrypted LV within an existing LVM setup. Reading those man pages it looks like I could also convert in place existing LVs, but my understanding is far from complete. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
