Bruno,

Thanks for continuing to look at this.

Let me know if you need any other info from us (our grub2 config, etc).  Also, FYI, before backing up & restoring the VM, “grub2-install /dev/vda” runs successfully.

Cheers,
Keven

That's indeed the issue. The grub2-install call fails. I now really need to reproduce on my side to debug the context at restore time, and see what neends to be done to avoid that error.
It'll take a bit more time that I'd have expected. Will come back when I have somethign for you to test again.

Best regards,
bruno.

Still fails to boot, just stuck at “Booting from Hard Disk…”.

I still see issues 2 & 3 mentioned previously in the mondorestore log.

Both logs attached.

Thanks for your further investigation,
Keven

I've seen that in some cases indeed. Would you mind testing the version available at
ftp://ftp.mondorescue.org/test/centos/7/x86_64/<ftp://ftp.mondorescue.org/test/centos/7/x86_64/> ?
The 3.3.0 version should hopefully fix this. If not, please report again with the same log file (+ the archive one) so I can work on it.

Best regards,
Bruno.

  Hi folks,

I'm having an issue with my mondorestore'ed VM failing to boot after the
post-mondorestore reboot.  I believe the bootloader (GRUB2) is not being
setup correctly by mondorestore.

I've attached mondorestore.log, and I have 3 areas of concern:
1.
INFO: Found Device /dev/vda has a MBR partition type partition table format
type on /dev/vda
DBG2: [Main] ../src/mondorestore/mondo-prep.c->partition_device#1539:
partition_device('/dev/vda', 1, 0, 'xfs', 1048576) --- starting
DBG2: [Main] ../src/mondorestore/mondo-prep.c->partition_device#1554:
Partitioning device /dev/vda1 (1024 MB)
INFO: Found Device /dev/vda has a MBR partition type partition table format
type on /dev/vda
DBG1: [Main] ../src/mondorestore/mondo-prep.c->partition_device#1616: Doing
the new all-in-one fdisk thing
DBG1: [Main] ../src/mondorestore/mondo-prep.c->partition_device#1617:
output = 'n
p

'
DBG1: [Main] ../src/mondorestore/mondo-prep.c->partition_device#1624: last
line = p
DBG1: [Main] ../src/mondorestore/mondo-prep.c->partition_device#1625:
Failed to create partition 1 on /dev/vda; sending 'Enter'...

What would cause this?

2.
DBG2: [Main] ../src/mondorestore/mondo-rstr-tools.c->run_grub#1476: mr-grub
/dev/vda /tmp/mountlist.txt
Now I'll use grub-install
Launching: chroot /mnt/RESTORING grub-install /dev/vda
chroot: can't execute 'grub-install': No such file or directory
grub-install returned 127
Now I'll use grub2-install
Installing for i386-pc platform.
grub2-install: error: cannot find a GRUB drive for /dev/vda1.  Check your
device.map.
grub2-install returned 1

The device.map file has "dev/vda".  I’ve also tried manually changing
device.map to “/dev/vda1”, but I still see the same error. Any ideas why
this might be occurring?

3.
Trying a hack
Checking usr/lib/grub/i386-pc
Cannot find BOOTPATHNAME
.............Cool.
device (hd0) /dev/vda
root (hd0,0)
setup (hd0)
quit
chroot: can't execute 'grub': No such file or directory
Hack returned res=0

This is a bug in try_grub_hack() of mr-grub.  If grub can't be found, the
function returns a false positive.

Any help that anyone could provide would be very appreciated.

Thanks in advance,
Keven
