Subject: [dm-crypt] Is removing a HDD after umount, without remove, considered safe?
Date: Mon, 6 Feb 2012 15:14:08 +0100 [thread overview]
Message-ID: <20120206141408.GA29217@citd.de> (raw)
Hi
I want to integrate a dm-crypted USB-HDD with autofs.
The first part of setting up dm-crypt can be put into udev, so that the
dm-crypt-device is setup immediatly after plugging in the HDD, which in
turn can then be used with autofs.
So my question is: Is it safe to unplug the HDD after the filesystem is
umounted, but with the dm-crypt-device still in existance?
(IOW: Are all dirty blocks immediately written to the HDD (at least at
umount-time), or can there be something still buffered in the dm-crypt
device?)
Bis denn

cryptic, powerful, unforgiving, dangerous.
