Help with restoring a partition Amanda [SOLVED]

[Sharpy (Aaron Sharp)]

hi everyone i’m having some major trouble

I noticed i had alot of updates (44) when logged into ssh. i do keep my system upto date but these ones have piled up

So i used the openhabian-config too update and now my system is pretty much entirely unresponsive UI’s starting and closing constantly , SSH refusing connections ,

what should i do ?

restore from backup before i updated?
Start fresh?
try too fix the current setup?

I had some similar issues when updating from 2.4, I resolved by downgrading back to 2.4 stable and haven’t had the time to troubleshoot. Will hopefully get a chance this weekend to try again and get it working.

[Sharpy (Aaron Sharp)]

Hi again @H102

I didn’t upgrade OH itself just all the installed packages

[H102 (CM6.5 H102)]

Ah, then I would restore from the backup.

[Sharpy (Aaron Sharp)]

Can someone give me some pointers on restoring a partition this is the first time i have needed to do this its taken days too even get this far

i’m receiving an error while trying to use amfetchdump

[20:24:26] backup@openHABianPi:/media/OHBackup/slots$ amfetchdump -p openhab-dir openHABianpi /dev/mmcblk0 > /media/OHBackup/temp/openhabianpi-image
WARNING: Fetch first dump only because of -p argument
1 volume(s) needed for restoration
The following volumes are needed: openHABian-openhab-dir-009
Press enter when ready

Volume '' not found

Insert volume labeled '' in chg-disk:/media/OHBackup/slots
and press enter, or ^D to abort.

[mstormi (Markus Storm)]

As the docs say: open another terminal and use amtape to find the slot to contain the volume.
Use the show command to find the volume amfetchdump asked for, then use the slot command to select it, e.g.

[22:46:31] backup@openhabianpi:/volatile/backup/slots$ amtape openhab-dir show

[Sharpy (Aaron Sharp)]

Hi @mstormi thanks for the reply i’m realy stuck here and its driving me crazy

@mstormi

amtape openhab-dir slot 3

i have already tried the second terminal thing but trying again get same results

@mstormi

amtape openhab-dir show

[20:28:50] backup@openHABianPi:/home/openhabian$ amtape openhab-dir show
amtape: scanning all 15 slots in changer:

slot   8: date 20190221010002 label openHABian-openhab-dir-008

openHABian-openhab-dir-009 is in slot 9

[21:55:56] backup@openHABianPi:/media/OHBackup/temp$ amtape openhab-dir slot 9
slot   9: time 20190211010002 label openHABian-openhab-dir-009
changed to slot 9

and then pressing enter on the first terminal brings up the same error

[21:55:15] backup@openHABianPi:/home/openhabian$ amfetchdump -p openhab-dir openHABianpi /dev/mmcblk0 > /media/OHBackup/temp/openhabianpi-image

[mstormi (Markus Storm)]

Don’t know that error sorry.
You can try the -a option to amfetchdump
Or without -p but in that case ensure you’re in a directory to have enough space.

There’s extensive logfiles in /var/log/amanda/, see if you find any hint there.
Read manpage (man amfetchdump) and if that still doesn’t help you could look for this
in the Amanda resources on the Inet such as http://forums.zmanda.com.

[Sharpy (Aaron Sharp)]

@mstormi

You can try the -a option to amfetchdump
Or without -p

Both return the same value volume “” not found

[mstormi (Markus Storm)]

Two more ideas:

1. the error could mean that the partition you’re trying to restore isn’t on that volume.
   Try restoring an older version (see manpage, I think you need to append the date to the amfetchdump command). You can use amadmin openhab-dir find to list all dumps.
2. manually search the files in your storage directories. See last paragraph of Amanda README for how to decode them.

[Sharpy (Aaron Sharp)]

Using this command seems too have done more im not sure what but its doing something looks like it needed a filename

amfetchdump -p openhab-dir openHABianpi /dev/mmcblk0 20190219010002 > /media/OHBackup/temp/openhabianpi-image

[Sharpy (Aaron Sharp)]

@mstormi

it seems too have restored quite an old version of the system strange as the date on the file was only a few days ago

need too put some work in but system might be back online now

[matt1 (Skinah)]

@Sharpy

update and now my system is pretty much entirely unresponsive UI’s starting and closing constantly , SSH refusing connections ,

I had the same thing happen to me last week, updated linux not openhab using apt manually on my Ubuntu minimal Odroid C2 setup and I could no longer use SSH and Openhab failed to start. Quick to fix for me as I had a good backup for this exact reason, see here…

How to: The method I use to backup my PI and C2 based Openhab

There are a number of ways to backup a SD card including Amanda which is popular. I’m sure all of them are good, but I thought I would share my backup system not just the software I use, but also the method and the reasons why, in case you find it useful. I recently found a program called Paragon Hard Disk Manager (PHDM) which is free for home use. There is also an opensource Program called Clonezilla https://clonezilla.org/ Edit: Looks like Paragon split the free features into a separate prog…

[mstormi (Markus Storm)]

As per default Amanda should also be backing up /etc/openhab2 and /var/lib/openhab2 you might be able to restore newer versions of those and extract the files you need.

[Sharpy (Aaron Sharp)]

my setup seems too be running again now and i have learned how too restore from amanda im just having some persistence errors maby you can help

Im getting it for quite a few items only since restoring the partition

[mstormi (Markus Storm)]

That has nothing to do with backups or Amanda so please move your question to a new thread.

[Sharpy (Aaron Sharp)]

@mstormi

Ok thats fine

it did start after the restore so i thought it was best posting under this thread

Thanks for the help on restoring the partition
