Igor,
I meant to reply to the group to let them know that the problem
had been solved, but your email makes me think that it has not
been solved fully. The script runs as user backuppc and
apparently user backuppc did not have permission to write to the
data locations. Once I fixed the permissions issue, the command
start stop command would work and give me an "ok."
What makes me think that the problem has not been solved fully
is that when I run the first two of your commands, I get no
response (as expected) and the testgram is created properly.
However, your third command does gives me an error that I don't
understand. Below are the results:
backuppc@linux-pc5:/data/BackupPC/pc$ touch
/data/BackupPC/pc/testgram
backuppc@linux-pc5:/data/BackupPC/pc$
backuppc@linux-pc5:/$ ln /data/BackupPC/pc/testgram
/data/BackupPC/cpool
backuppc@linux-pc5:/$
backuppc@linux-pc5:/$ rm /data/BackupPC/pc/testgram
/data/BackupPC/cpool
rm: cannot remove ‘/data/BackupPC/cpool’: Is a directory
Is the output what was to be expected? A couple of things are
throwing me for a loop. First, on the remove command "rm
/data/BackupPC/pc/testgram /data/BackupPC/cpool", should that
really be "rm /data/BackupPC/pc/testgram
/data/BackupPC/cpool/testgram" and is that the nature of the Is
a directory error? I presume so. Or should my merely removing
the linked target also remove the linked file?
Second, the "could not find valid filesystem superblock error is
unclear.
Yes, this error is expected based on the commands you were given. It
would help if you understood the commands you run, as sometimes you
will be told to run something that could be highly destructive (even
if by accident).
In this case, you had the command:
backuppc@linux-pc5:/$ rm /data/BackupPC/pc/testgram
/data/BackupPC/cpool
rm: cannot remove ‘/data/BackupPC/cpool’: Is a directory
Which says remove the two files /data/BackupPC/pc/testgram
and /data/BackupPC/cpool, but the second is a directory, not a file.
So rm is complaining that you asked it to remove a file, but it
wasn't a file. The command should have been:
rm /data/BackupPC/pc/testgram /data/BackupPC/cpool/testgram

Adam
