#1593 PR merged: Let the user enforce MIGRATION_MODE¶
Labels: enhancement, bug, fixed / solved / done
jsmeix opened issue at 2017-11-22 16:17:¶
When the user can (if needed) enforce MIGRATION_MODE
he can avoid a disastrous disaster recovery as in
https://github.com/rear/rear/issues/1271
By the way I found a bug in layout/prepare/default/300_map_disks.sh
because for same disk with same size it mapped
e.g. /dev/sda to /sys/block/sda but the latter is no
block device which lets "rear recover" BugError out with
BUG in /usr/share/rear/layout/prepare/GNU/Linux/100_include_partition_code.sh line 35: 'Disk /sys/block/sda is not a block device.'

A quick "rear recover" test worked for me
but I need to do some more tests...
jsmeix commented at 2017-11-23 08:21:¶
I never liked my current hardcoded fixed 10 seconds timeout
for the UserInput but yesterday I had no better idea
but - as always - sleeping over it helped so that I got
an idea how I could properly implement it ...

@gdha
many thanks for having a look at my code and
even more thanks for your automated testing!
Now when "Disk configuration looks identical"
there is still a UserInput() confirmation dialog
with 30 seconds timeout to be on the safe side.
To avoid that 30 seconds delays during automated testing
you can specify
# export MIGRATION_MODE='false'
directly before calling "rear recover"
(or specify that in local.conf)
or
you can specify
# export USER_INPUT_TIMEOUT=1
directly before calling "rear recover"
(or specify that in local.conf)
or
you can specify
# export USER_INPUT_DISK_LAYOUT_PROCEED_RECOVERY='y'
perhaps even together with
# export USER_INPUT_INTERRUPT_TIMEOUT=1
directly before calling "rear recover"
(or specify that in local.conf)

@schabrolles
I would appreciate it if you could test how that behaves for you
on your systems in particular in case of multipath migration.
