Hokay, I'm stuck. I give. I need help.
The documentation for UserCmdCheckStatus says:
"Whether the exit status of each PreUserCmd and PostUserCmd is
checked.
"If set and the Dump/Restore/Archive Pre/Post UserCmd returns a
non-zero exit status then the dump/restore/archive is aborted. To
maintain backward compatibility (where the exit status in early
versions was always ignored), this flag defaults to 0.
"If this flag is set and the Dump/Restore/Archive PreUserCmd
fails then the matching Dump/Restore/Archive PostUserCmd is not
executed. If DumpPreShareCmd returns a non-exit status, then
DumpPostShareCmd is not executed, but the DumpPostUserCmd is still
run (since DumpPreUserCmd must have previously succeeded).
"An example of a DumpPreUserCmd that might fail is a script that
snapshots or dumps a database which fails because of some database
error."
Simple enough - so I wrote a script to verify that the location to
which I am about to try to backup actually exists (I'm backing up to
a removable drive that does get removed, from time to time, and I
only want the backups to run when the drive is attached). Then I set
this script to the value for the various Pre conditions:
$Conf{DumpPreUserCmd} = '$sshPath -q -x -l kimball $host /usr/local/
bin/checkHonker';
$Conf{DumpPostUserCmd} = undef;
$Conf{DumpPreShareCmd} = '$sshPath -q -x -l kimball $host /usr/local/
bin/checkHonker';
$Conf{DumpPostShareCmd} = undef;
$Conf{RestorePreUserCmd} = '$sshPath -q -x -l kimball $host /usr/
local/bin/checkHonker';
$Conf{RestorePostUserCmd} = undef;
$Conf{ArchivePreUserCmd} = '$sshPath -q -x -l kimball $host /usr/
local/bin/checkHonker';
$Conf{ArchivePostUserCmd} = undef;
and I set it to check the status of the user commands:
$Conf{UserCmdCheckStatus} = 1;
But it still runs the backup (and writes over my mount point for my
external drive)
I've verified that the script returns a non-zero when the drive is
not present:
sillyHost:~ backuppc$ /usr/bin/ssh -q -x -l kimball 192.168.0.21 /usr/
local/bin/checkHonker
Checking for Honker
Honker NOT mounted
sillyHost:~ backuppc $ echo $?
1
What am I missing?
-- Kimball
