CentOS 6.
I have the entry in /etc/crypttab, and a key in /etc/crypt.pw, and the
luks UUID in /etc/fstab. I cannot find the command that tells it to
create the device in /dev/mapper from the info in /etc/crypttab.

Thank you *very* much for the help, and such fast responses. Googling
hadn't been helpful
I'm good now (and will be documenting it for my manager and the other admin).

unmap: cryptsetup luksClose /dev/mapper/luks
and then try again with following correction
NOT ...UUID $(/dev/sdb)
...UUID /dev/sdb

Something's not right. I did
cryptsetup luksOpen /dev/sdb luks-$(cryptsetup luksUUID $(/dev/sdb))
--key-file /etc/crypt.pw
It did want the password, so I added --key-file, but it seems to have
created /dev/mapper/luks, not the full luksUUID that's in both crypttab
and fstab.

[CentOS] CentOS 6 and luksOpen
Upgraded a RAID. Copied everything from backup. And then my manager said I had to encrypt the drive. I've done that, and made the filesystem, but I can't mount it. CentOS 6. I have the entry in /etc/crypttab, and a key in /etc/crypt.pw, and the luks UUID in /etc/fstab. I cannot find the command that tells it to create the device in /dev/mapper from the info in /etc/crypttab. Clues for the poor? Yes, the server will, at some point in the future, go to CentOS 7, but that needs my user to be off for a while, and his jobs run literally for weeks, with loads upwords of 30 on an HBS (honkin' big server) mark ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
