(Its a uefi setup) Well this morning - - - fdisk -l shows the array its not mounted
fdisk doesn't know anything about what is mounted and where. For mounted stuffs, try - df, mount, lsblk -f - /proc/mounts, /etc/mtab

Weird.

The last two return the same result as #mount.
the command I used to use for mounting in Debian 7 no longer works
so - - - - any suggestions?
Which command?
mount /dev/dm-0 /home/myhome/RAID
I have been using the suspend command on my LXDE manager - - - wondering if that might have something to do with the problem.
So the array (raid10) is there but it is not getting mounted. The mdadm man page isn't very useful for this issue being so terse to be almost useless. There is really only information for the establishment and repair but none for remount or any mounting issues!
What entry do you have for your raid stuff in /etc/fstab?
# /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed.

And as already said, software raid does NOT use /dev/dm devices, it uses /dev/md devices. dm is for device mapper, which you will see if you use dmraid (which I think most people have fortunately stopped doing), or lvm (which many people are using) or encrypted disks (which some people use).
What does fdisk -l /dev/md0 show? Did you partition the raid or is the filesystem on the full raid?

I have not been able to find anything that remotely resembles this problem, nor have I found anything that seems like it might be a solution. There seems to be some hints that this might be a problem between mdadm and systemd and my file manager on LXDE (PCManFM). Thanking all for their hints and tips!! Dee
