[Bug 30995] Re: dm_mod causes false busy on mount attempts

[wna]

Some days ago I had a similar problem after an update:

Machine has two SATA drives.
I had /boot and swap on primary partitions /dev/sda1 and /dev/sda2,
/ and other filesystems on Software-RAID-1 and LVM. 

After the issue neither /boot nor swap was recognized on /dev/sda*.
Instead it was mapped to /dev/evms/sda*. The RAID and LVM devices on
/dev/md* and /dev/mapper/* worked fine though.

$ sudo mount /dev/sda1 /boot
mount: /dev/sda1 already mounted or /boot busy
$ sudo mount /dev/evms/sda1 /boot
$ sudo swapon /dev/sda2
swapon: /dev/sda2: Invalid argument
$ sudo swapon /dev/evms/sda2
$

This cost me quite some time to figure out ;-(

Is this intended, i.e. should I change my fstab to point to /dev/evms/*
?
