#2227 Issue closed: ERROR: No filesystem mounted on '/mnt/local'. Stopping

I am trying to use rear to create a virtual copy from a physical system.
The virtual system is indeed different from the physical system and this is likely the reason for the above error message but I am trying to overcome this anyhow.

Description of the issue

We are having suse sles12sp4 on power lpar,,,we installed the rear rpm packate and using that created rear iso image ,,,now we took this image and mounted it on another lpar and we get into resuce mode ,,when we run #rear recover command we get the below error

Start system layout restoration.

Disk layout created.

i guess i have provided the details you have rqeusted for please let me know if you need any additonal details

hamantri commented at 2019-09-06 08:21:

actually there is another input that migth be addition to your investigation,,both the the source lpar and destination lpar where i am try to put the iso image are lpars they are not phyiscal ,,,on poweor systems we call it lpars,,,,

the lpar on which the iso image it taken is having rootvg disk named as mpathh,,,the lpar on which the image i am trying to load is having only one disk and the disk is named as mpatha,,,for me this should not be a cause of concern but yes if it adds on to your investigation it would good

hi any luck on my query

andreasberner commented at 2019-09-06 12:23:

Hi Hamntri,
thank you for your multiple responses. I appreciate that.
However, I am afraid I can't relate your anwers to my question.
Are you sure you anwered my question?

gozora commented at 2019-09-06 12:55:

@andreasberner, I don't have exact answer for your problem, but I'd recommend you to start with storing your ReaR recovery system (ISO) and backup separately on some remote (CIFS or NFS) share.

Something like:


here you can find some easy and tested configuration examples.

Be aware file:// as a destination can be quite tricky and might require some hacks to work correctly ...


gozora commented at 2019-09-06 13:07:

@hamantri I'm somehow confused by your posts. As @andreasberner already wrote, they looks to be unrelated to this issue.
If you want, you can open new issue by filling the template here.


andreasberner commented at 2019-09-06 13:55:

@gozora: Thank you for your advice the source server is in a remote location and I would do hard to store the backup somewhere else if not on file. I have already used rear on a different hardware where I store everything on a mounted USB-Stick and this works like a charm.
Can you explain a bit more into detail why storing the resulting backup in a file would be problematic?
Of course I moved away to the iso to the cd of the desingated copy computer right after creating the iso on the source.

gozora commented at 2019-09-06 14:03:

Well, I'm afraid I can't give you qualified answer, because I've never actually used file://. and honestly I have just foggy idea how it works ...
Anyhow, as far as I remember there has been some people already having trouble when they used file://, so you can search in closed issues and maybe you will find something usefull ...


jsmeix commented at 2019-09-10 14:49:

in general when you like to recreate on different hardware
(where "hardware" could be also virtual hardware)
things can get soon rather complicated, see my
explanations in the mail thread with subject
"Move from bare-metal2vm ?"
on the "rear-users" mailing list at

gdha commented at 2019-11-29 09:11:

@andreasberner Did you looked at the target system in detail when this issue happened? Were the file systems created? Could you inspect this with fdisk or parted? vgs, lvs and pvs commands?
The error seems to be related that the desired file system was not created somehow. The logs should tell you more what really happened as these are quite detailed for that section (in creating the disk partitions and so on).

gdha commented at 2020-01-23 15:36:

@andreasberner Is this issue still relevant? I see Debian, Sles and lpar ?? Very confusing...

jsmeix commented at 2020-01-27 13:11:

I think the confusing SLES and lpar you see are in comment
but This comment was marked as off-topic. by me.

jsmeix commented at 2020-06-24 10:58:

Because "no news is good news" I close it.
