Hi Brett,

I think running the ldapsearch, and checking for error 32 is the easiest option. 

I know you're not hitting this, but there are times when the task will stick around for a minute after its completed.  In that case, you can search for the task, and request the attribute "nsTaskStatus".  Then grep the value for "Backup finished", or "Backup failed".

Regards,
Mark

Oops, the ldapsearch –b is wrong I think the search should be

 

ldapsearch -x -H ${HOST} -D ${BINDAS} -b ' cn=backup,cn=tasks,cn=config' -y ${PWFILE} 'cn=<tasked>'

 

 

In short, if I immediately start the tar task after running db2bak.pl in my script, the target backup directory doesn’t exist.

So I need to check if the backup task has finished.

The DB is so small here though that that task has finished ( and the task deleted ) before I can run an ldapsearch to check the base and filter (even if I put it in the script before ‘tar’).

Subject: Re: [389-users] How to tell when database backup has finished?

 

Bit of a fiddle:

 

Execute the d2bak.pl script in verbose mode and extract the task name:

task=$(${BACKUPCMD} -v -D "${BINDAS}" ${BACKUPOPTS} -a ${DSBACKUPDIR} 2> /dev/null | grep "^adding new entry" )

ERR=$?

task=${task#*\"}

taskDN=${task%?}

 

Syslog message and exit if script failed:

if [ $ERR -ne 0 ]; then

        LogIt "FAILED (${ERR})." "user.err";

        exit 1;

fi

 

Until “task” isn’t found ( 32 ) hang around here....:

while [ ${ERR} != 32 ]; do

        (ldapsearch -x -H ${HOST} -D ${BINDAS} -b '${taskDN}' -y ${PWFILE} > /dev/null 2>&1 )

        ERR=$?

        if [ ${ERR} != 32 ]; then

                sleep 5s

        fi

done

 

 

Again any thoughts welcomed.

 

Brett
