#984 Issue closed: Name of the generated ISO or auto-creation of FTP-Directory

  • rear version (/usr/sbin/rear -V): Relax-and-Recover 1.17.2 / Git
  • OS version (cat /etc/rear/os.conf or lsb_release -a): CentOS release 6.7 (Final)

Hello,

I would like to include REAR to my Puppet-Deployment. To do so I would like to use FTP as output_url, which works fine.

But: The name of the generated iso is rear-1.iso in one case, which could be the name of another system aswell.

In Puppet I managed to create a configuration that adds a FTP-folder to the output_url - but if that folder does not exist the upload fails.

So my questions are:

  • Is it possible to create an iso by using the fqdn?
  • Is it possible to auto-create a folder to FTP if it does not exist?

I tested current GitHub master code
on my SLES12-SP2-RC1 test system with

OUTPUT=ISO
OUTPUT_URL=ftp://10.160.4.244/rear
BACKUP=NETFS
BACKUP_OPTIONS="nfsvers=3,nolock"
BACKUP_URL=nfs://10.160.4.244/nfs

and on the test host d245 "rear -d -D mkbackup"
results on my NFS and FTP server 10.160.4.244

# ls -lh /srv/ftp/rear/
total 159M
-rw------- 1 ftp ftp   62 Aug 25 12:37 README
-rw------- 1 ftp ftp 150M Aug 25 12:37 rear-d245.iso
-rw------- 1 ftp ftp 8.5M Aug 25 12:37 rear.log
-rw------- 1 ftp ftp  262 Aug 25 12:37 VERSION
# ls -lh /nfs/d245
total 700M
-rw------- 1 nobody nogroup 700M Aug 25 12:38 backup.tar.gz
-rw------- 1 nobody nogroup    0 Aug 25 12:37 .lockfile

I.e. I get the hostname of the system where "rear mkbackup"
was run in the ISO file "rear-d245.iso" and the backup
in a "d245" directory.

With

OUTPUT_URL=ftp://10.160.4.244/rear/$HOSTNAME

"rear mkbackup" does not automatically create the
hostname directory on the FTP server but fails with

Copying result files '/root/rear/var/lib/rear/output/rear-d245.iso /myreartmp/rear.DfguWh3MnUvQSxk/tmp/VERSION /myreartmp/rear.DfguWh3MnUvQSxk/tmp/README /myreartmp/rear.DfguWh3MnUvQSxk/tmp/rear.log' to ftp location
ERROR: Problem transferring result files to ftp://10.160.4.244/rear/d245
Aborting due to an error, check /root/rear/var/log/rear/rear-d245.log for details

But when I manually create that directory on the FTP server
it "just works".

I.e. when you know in advance the hostnames, create
matching directories in advance on your FTP server.

Ah!
I did not notice that you wrote "using the fqdn".
See usr/share/rear/conf/default.conf

ISO_PREFIX="rear-$HOSTNAME"

But I wonder abut your case where the hostname
seems to be "1" - is this really the intended hostname?
If yes, you should not use same hostnames on
different systems.
If no, I think you need to fix that system so that
it has the actually intended hostname.

FYI:

ISO_PREFIX="rear-$( hostname ).$( domainname )"

"just works" for me.
