I know over the top security precautions gone mad! This user has the path etc set up to run the test programs.</div><div><br></div><div>I plan to bring a Ubuntu / win8 laptop with a couple of card readers on Friday and a screen keyboard etc for the master node (other nodes don't need screen etc). I've also got half a dozen net cables. Will have a think of anything else we might need. </div><div><br></div><div>Malcolm</div><div><br></div><div><br></div><div><br></div><br><br><br>-------- Original message --------<br>From: Paul Sutton <zleap@zleap.net> <br>Date: 10/12/2013 12:55 (GMT+00:00) <br>To: Exeter LUG Mailing List <exeter@mailman.lug.org.uk> <br>Subject: Re: [ExeterLUG] pi cluster image errors <br> <br><br>On 10/12/13 12:42, Paul Sutton wrote:<br>> Hi<br>><br>> Just tried to create the sd card image for friday<br>><br>> using<br>><br>> psutton@e-machines:~/Documents/raspberrypi/picluster$ sudo dd bs=1M<br>> if=arch-rpi-cluster-2013-11-29.img of=/dev/sdb<br>> 1691+1 records in<br>> 1691+1 records out<br>> 1773158400 bytes (1.8 GB) copied, 349.336 s, 5.1 MB/s<br>> psutton@e-machines:~/Documents/raspberrypi/picluster$ ls /dev/sdb<br>> /dev/sdb<br>> psutton@e-machines:~/Documents/raspberrypi/picluster$<br>><br>> this seems to go fine, when i then try and mount the devicer in PCManFM<br>><br>> i get the following<br>><br>> Error mounting /dev/sdb1 at /media/psutton/3163-3434: Command-line<br>> `mount -t "vfat" -o<br>> "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush"<br>> "/dev/sdb1" "/media/psutton/3163-3434"' exited with non-zero exit status<br>> 32: mount: wrong fs type, bad option, bad superblock on /dev/sdb1,<br>> missing codepage or helper program, or other error<br>> In some cases useful info is found in syslog - try<br>> dmesg | tail or so<br>><br>><br>> doing dmesg | tail or so, comes up with<br>><br>> tail: cannot open ‘or’ for reading: No such file or directory<br>> tail: cannot open ‘so’ for reading: No such file or directory<br>><br>> can someone advise please I don't have time to fiddle with thisd until<br>> tomorrow due to work, rugby training etc, so hopefully someone can advise<br>><br>> if not can we create the sd card image on friday please, someone needs<br>> to bring a computer with sd card writer.<br>><br>> Paul<br>><br>><br>Ok further to this, removing the card. and reinserting it, so it mounts<br>again seems to mount it fine, giving me 2 partitions /boot and /arch<br>and files within.<br><br>Which brings me to the question why was it having issues in the first place<br><br>Paul<br><br>-- <br><br><br><br><br>--<br>http://www.zleap.net<br><br>http://www.linkedin.com/pub/paul-sutton/36/595/911<br><br>Exeter Lug meet : 13th December 2013 - http://exeter.lug.org.uk/<br>Torbay Raspberry Pi Jam 14th December 2013 - http://dcglug.drogon.net/torbay-pi-jam/<br><br>I am committed to safeguarding children, young people and vulnerable groups and expect any school or establishment I am involved with to share this commitment. <br><br><br><br>_______________________________________________<br>Exeter mailing list<br>Exeter@mailman.lug.org.uk<br>https://mailman.lug.org.uk/mailman/listinfo/exeter<br></body>
