Package: partman-md Version: 26 Severity: important Tags: patch, pending Probably since the the implementation of 2.6 with udev, partman tries to open /dev/md/x devices twice. This leads to a warning dialog "The device is already opened".
The attached log shows what happens in detail. Basically there are two
scripts that now both try open the device:
- /lib/partman/init.d/30parted (from partman-base)
- /lib/partman/init.d/31md-devices (from partman-md)
The change is probably that parted_devices in the 30parted script now
lists RAID devices while in the past it did not and thus the separate
script 31md-devices had to open the device.
Probable reason that parted_devices now lists RAID is that there is now a
symlink /dev/md0 -> /dev/md/0. Removal of that symlink causes
parted_devices to no longer list them.
In that respect this bug is related to #377242.
The patch below seems to solve the problem and should keep backwards
compatibility.
