I've thoroughly examined my setup and it looks I was wrong - USB drive, where mounting LUKS volume through nautilus works flawlessly, contains LUKS volume in primary partition! I did some some experiments with another USB drive, these are the results: 1) the whole device (/dev/sdd) used for LUKS volume: * nautilus asks for password * /dev/mapper/luks-something is created * _nothing_ is mounted [WRONG! WHY?] 2) primary partition (/dev/sdd1) used for LUKS volume: * nautilus asks for password * /dev/mapper/luks-something is created * LUKS volume is mounted successfully: $ mount ... /dev/dm-0 on /media/disk type ext2 (rw,nosuid,nodev,uhelper=hal) (I wonder why /dev/dm-0 has been used instead of /dev/mapper/luks_crypto_cd724b68-5a6f-4016-9c9c-1572722aaee8, but they share the same major/minor device number (252,0), so it's probably the same.) $ ls -la /dev/dm-0 brw-rw---- 1 root disk 252, 0 1. čen 12.23 /dev/dm-0 $ ls -la /dev/mapper/luks_crypto_cd724b68-5a6f-4016-9c9c-1572722aaee8 brw-rw---- 1 root disk 252, 0 1. čen 12.23 /dev/mapper/luks_crypto_cd724b68-5a6f-4016-9c9c-1572722aaee8 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
