Hello
I had a power failure yesterday morning and because of that my server went down
because of no battery present.
When trying to mount the crypto partitions, I have figured out its not possible
anymore because a set of 2 errors, as follows:
# sh cryptfs -m -p /home -f /crypto/home/cryptofile -d /dev/svnd0c
Encryption key:
mount_ffs: /dev/svnd0c on /home: specified device does not match mounted device
#
and then, when trying again :
# sh cryptfs -m -p /home -f /crypto/home/cryptofile -d /dev/svnd0c
Encryption key:
vnconfig: VNDIOCSET: Device busy
mount_ffs: /dev/svnd0c on /home: specified device does not match mounted device
#
For further reference , cryptfs script is the following:
#!/bin/sh
#
# cryptfs
#
# mount/unmount blowfish encrypted filesystem
#
# Important Note: Under OpenBSD's current encrypted vnd filesystem
# implementation, when a system with a mounted, encrypted vnd filesystem
# is shutdown uncleanly, the encrypted vnd filesystem's structures get
# damaged and, since OpenBSD's fsck will not acknowledge vnd filesystems,
# these damaged structures can not reasonably be repaired.

#

sleep 1
/sbin/mount -o softdep,nosuid,nodev -f $svnd $cryptmnt

#

then
[ $verbose ] && /bin/echo "unmounting encrypted filesystem ..."
/sbin/umount $cryptmnt
sleep 1
/usr/sbin/vnconfig -u $verbose $svnd
exit
fi
Any advice / suggestions is highly recommended as I fear loosing my data, even
if I am sure there has to be a solution to this FS problem.
Thank you all in advance.
