Segmentation fault in the latest versions of Mondo on Ubuntu 10.04

Description (last modified by Bruno Cornec)

Running mondoarchive with command line options results very quickly in a segmentation violation. This critical bug can be reproduced every time using the too latest stable mondo/mindi packages from the ftp-server as well as the newest testing package of mondo/mindi for Ubuntu 10.04.

Output of mondoarchive:

"Initializing...

Hello,

You should not use the -I /dev/sda5 (of course that should not core dump either !! So I keep the BR open to fix that)

Just exclude what you do not want. -I is mostly for testing purposes.

Thanks bruno omitting the -I flag did work. The resulting command needs some more exclude flags:

sudo mondoarchive -OVN -i -E "/boot|/home|/kalinka/home|/kalinka/storage|/mnt/old_kalinka" -d /home/admin/backup/mondo -s 4400M -S /home/admin/temp/mondo/scratch/ -T /home/admin/temp/mondo/tmp/

I think the -I flag is quite useful in this case but if its not intended for normal use a short warning in the documentation would be helpful.

By the way the mondoarchive wizard is not capable using so many excludes (the input line is too short) and its seems not to be possible to "scroll" if you enter the text manually. But this is such a small problem not worth opening a ticket.

-I should work, and I now have a way to reproduce the problem so will fix it anyway.

I think it's already documented:

-I “path ...”
                    Include  paths(s)  in  backup.  The  paths should be separated with a pipe and surrounded by quotes.  This
                    option is mainly use to perform tests in order to reduce the time taken by the archiving  operation.   The
                    default  backup  path is “/” but you may specify alternatives, e.g. -I “/home|/etc” to override that.  You
                    may also specify full disk device to this option as with -I “/dev/sda|/dev/cciss/c0d0”  N.B.:  When  using
                    the  -I  option  with  the -E option, the -E content should be subdirectories of those mentioned in the -I
                    only, as -I takes precedence.

Let me know if you think some more details should be added.

For the scrolling issue, there is already a bug report for it: http://trac.mondorescue.org/ticket/231 which in fact concerns all newt fields. Not before 2.2.10 (or wahtever name it will have).

Milestone: 2.2.102.2.9.7
Resolution: fixed
Status: assignedclosed

Core dumped with -I should be fixed by rev [2836].

Could you check with the version available at: ftp://ftp.mondorescue.org/test/ubuntu/10.04 (tag: 20110421135204)

Great the -I flag is working flawlessly now. Thanks bruno!
