Hello,
I recently upgraded my raid array from 4 to 5 disks,
and mount no longer shows lv names but is /dev/dm-* style instead.
My setup is lvm on softraid
blkid, cat /proc/mounts, df, etc.. are all affected
How can I recover the normal behavior? Is it really caused by my
upgrade?
I recreated /etc/blkid, /etc/lvm/.cache.
I straced blkid (with no cache): it reads directly the data
from /proc/partitions.
cat /proc/partitions shows (edited for simplicity)
major minor #blocks name

Should I file a bug? And if so, to which component
example of output:
