Strange but following an update my multimedia data, about 4TB worth, no longer is sitting within my home directory tree. When I checked the partition I find it is not mounted.
Any views as to why after years of use this setup has broken and please remind me how I mount it so it is “permanently” part of the home directory tree.
Just a bit nervous when strange things happen and so much is at stake.
Are there any log entries indicating a problem? Have you checked “dmesg” to see if it indicates a problem?
You might try (as root)
fsck /dev/sda5
to see if that shows any issues.
And if that is clean, try manually mounting and see if there are any errors.
Maybe post the relevant line from “/etc/fstab”.
And please show us
cat /etc/fstab
so we can see what the entry is.
And apart from the fsck, you could also do a
mount -a
to see if it mounts or what the error messages are.
Hi and many thanks for the speedy response.
The partition in question is shown from the partitioner as:-
- File System: XFS
- Mount Point: /multimedia (not mounted)
- Mount By: UUID
- Label:
- UUID: 4272b75a-ea72-4068-8826-e2dfc5611fd5
dmesg has no obvious issues except the last few lines which suggest a USB drive was not properly unmounted. (it was)
fsck was less help than I expected:-
install:~ # fsck /dev/sda5
fsck from util-linux 2.34
If you wish to check the consistency of an XFS filesystem or

and here is fstab:-
install:/etc # cat fstab

In my home directory there is an entry which is in yellow on red background and if I look at the properties it seems this is what remains of the link which should connect to the partition which has been unmounted.
Can I do any harm by trying to mount /etc/sda5 and how should I do this exactly?
I assume yhis is the one you mean:
UUID=4272b75a-ea72-4068-8826-e2dfc5611fd5 /multimedia xfs defaults 0 0
You can check that with:
ls -l /dev/disk/by-uuid | grep '4272b75a-ea72-4068-8826-e2dfc5611fd5'
It should link to /dev/sda5.
First you said that it is not mounted.
Now you tell that there is a link in the home directory of a particular user that links to /multimedia and that that link shows strange things, I assume in some GUI tool. Which does not mean it is not mounted.
Thus please first check if it is mounted:
mount | grep media
And of course show that symlink. browse to that home directory and do an ls -l of it:
cd /home/.....
ls -l .....
And where is the
mount -a
I asked for?
Hi Henk, I believe my explanation so far is correct. The partitioner shows /dev/sd5 is not mounted but the properties of directory entry /home/alastair/master show that there should be a link to /multimedia/multimedia when /dev/sda5 is mounted.
The reason I had not used the command mount -a was that I did not know the full situation and did not want to try and mount all until I was more confident the system had not been corrupted.
All the tests you subsequently suggested confirm this as follows:-
alastair@install:~> ls -l /dev/disk/by-uuid | grep '4272b75a-ea72-4068-8826-e2dfc5611fd5'
lrwxrwxrwx 1 root root 10 Oct 9 16:19 4272b75a-ea72-4068-8826-e2dfc5611fd5 -> ../../sda5
alastair@install:~> mount | grep media
alastair@install:~> ls -l
total 153

I have now taken the plunge and mounted all and the mounted partition has picked up the link and all is working as it should. What I do not know still is why the partition became unmounted in the first place following a re-boot after a Tumbleweed update.
Many thanks to all for the help and guidance. I shall see what happens with the next re-boot which with Tumbleweed will not be long away!
Regards and thanks again,
OK, nice it works again. Indeed, the fact that we do not know exactly why it wasn’t mounted is a bit frustrating. Just watching is the best.
And next time, as always, it is far better to not (only) tell your conclusions, but show computer facts. Then others can draw their own conclusions. You have seen the commands above and they provide far more factual information then trying to tell what you see in the window of some silly GUI tool.
