RE: newbie ? - tapeless operation -> amlabel error

Hi, Jeanna,

The setting I mentioned, pointing tapedev at the "slots" directory on disk, is what I use for writing to virtual tapes, i.e. writing to disk. Did you notice that the HOWTO you are using is dated Nov 2001? A lot has changed since then. Try the HOWTO in the wiki at:
http://wiki.zmanda.com/index.php/Test_environment_with_virtual_tapes

I also referred to other pages on the wiki:
http://wiki.zmanda.com/index.php/File_driver
http://wiki.zmanda.com/index.php/Changers

And when I was creating many slots this afternoon, I recorded the following notes (copied from the wiki I use internally at work). Lots of this is specific to my configuration, like the user names. Note that the phrase `seq 1 50` and similar are enclosed in back-quotes and all of this was done in the bash shell:

Mount the new disk on /mnt/Amanda/Set2 where 2 is the number for the backup disk, could be 3 for instance

As root, create vtapes folder on the backup disk, set owner amandabackup user, group disk, not readable or executable by "other"

mkdir vtapes
chown amandabackup:disk vtapes
chmod 750 vtapes

Change to the amandabackup user.

Create a DailySet2 folder inside vtapes

Create slots inside vtapes/DailySet2

for i in `seq 1 50`; do mkdir slot$i; done

Put it "online" by creating the required data symlink

ln -s slot1 data

Check it - this command should return ONLINE

ammt -f file:/mnt/Amanda/Set2/vtapes/DailySet2/slots/ status

Label the tapes - the changer must be "online" first

for i in `seq 1 9`; do amlabel DailySet2 DailySet2-0${i}; done
for i in `seq 10 50`; do amlabel DailySet2 DailySet2-${i}; done

Check it's OK

amcheck DailySet2

Thanks so much for the reply!

I can change that parameter value, however, in the 'HOWTO'
I was following, it tells me to comment out that specific
parameter so I don't think that will help:

   ---------------------------------
   /etc/amanda/DailySet1/amanda.conf
   ---------------------------------
   # These are the options that differ from
   examples/amanda.conf

   dumpcycle 14 days
   tapecycle 14
   #runspercycle # defaults to 1 per day

   runtapes 1
   tpchanger "chg-multi"
   changerfile "/etc/amanda/DailySet1/changer.conf"
   # Comment out tapedev and changerdev

Thanks for the input, though - I'll make sure the
double-check the value so when I do get ready to write it
to tape, the value is correct!
