I am running on the Centos 6.5 x86_64 boot disk.
# uname -a
Linux localhost.localdomain 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
I have been running ddrescue for a while and now it is time to check the progress.
I want to take the oldhd.img output from ddrescue and load it to satrt performing recovery (LVM, then filesystem) but I want to do a copy on write with that.
I fetched http://www.atcomputing.nl/Tools/cowloop/packages/cowloop-3.2.0.1.tar.gz, built it
root@localhost ~/cowloop-3.2.0.1
# cowdev -a /root/oldhd.img /root/oldhd.cow
Cannot open /dev/cow/ctl: No such device or address
So I:
root@localhost /dev
# mkdir cow
root@localhost /dev
# cd cow/
root@localhost /dev/cow
# mknod /dev/cow/ctl b 241 255
But I still get a
root@localhost ~
# cowdev -a /root/oldhd.img /root/oldhd.cow
Cannot open /dev/cow/ctl: No such device or address
Listing /proc/devices I do not see 241.
What am I doing wrong here?
