I thought I had a tape issue.. Now its clear I have a script issue. Below is a script I use to perform level 0 dumps on all mounted file systems. The problem seems to be that when the script runs, it does not run as root -- even though I am root when I run it. The goal is to cron it, but as I was testing it I ran into some problems.
First, I can't set the MT variable as its listed below. I get an permission denial on /dev/nrsa0. This makes no sense, since as root I can issue the command fine. Moreover, the dump command itself fails even thought it seems to be rendered syntactically correct. I echo'ed all the generated commands just to make certain they are correct. Here's the output of the script: ===================================================== ppsrvx# ./l0dump.sh ./l0dump.sh: /dev/nrsa0: permission denied comp off /sbin/dump -0u -a -b 64 -f /dev/nrsa0 /dev/ad0s1a /sbin/dump -0u -a -b 64 -f /dev/nrsa0 /dev/da1s1d /sbin/dump -0u -a -b 64 -f /dev/nrsa0 /dev/da0s1e /sbin/dump -0u -a -b 64 -f /dev/nrsa0 /dev/da1s1e /sbin/dump -0u -a -b 64 -f /dev/nrsa0 /dev/ad0s1d /sbin/dump -0u -a -b 64 -f /dev/nrsa0 /dev/da0s1d /sbin/dump -0u -a -b 64 -f /dev/nrsa0 /dev/ad0s1e /dev/sa0 offline ====================================================== notice the permission denied.. not also 'comp off' which SHOULD be rendered as /usr/bin/mt -f /dev/nrsa0 comp off but isn't. I'm really stumped here. Is there some reason why running these commands in a script would fail, yet running them by hand works? ======================================================== #!/bin/sh AWK=/usr/bin/awk DF=/bin/df DMP=/sbin/dump DEST=/dev/nrsa0 MT="/usr/bin/mt -f " ${DEST} MOPTS='weof 1' DOPTS='-0u -a -b 64 -f ' # -b 64 is max, will never use large value FSS=`${DF} | ${AWK} '/dev/ {print $1}'` echo ${MT} 'comp off' # echo ${MT} 'blocksize 512' for FS in ${FSS} ; do echo ${DMP} ${DOPTS} ${DEST} ${FS} # ${MT} ${MOPTS} done echo ${MT} '/dev/sa0 offline' echo "Please swap tapes on srvx" | mail iddwb ======================================================== -- David Bear phone: 480-965-8257 fax: 480-965-9189 College of Public Programs/ASU Wilson Hall 232 Tempe, AZ 85287-0803 "Beware the IP portfolio, everyone will be suspect of trespassing" _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
