Automatically setting quotaugidlimit
If you are using second-level user/group quota with simfs for your containers, you have to take care that the value at every moment is high enough. Otherwise, newly created users and groups within the CT won't be able to own files. Note this is not required for ploop layout, in which quotaugidlimit is enabled with any non-zero value.
Rather than checking these values from time to time by hand, you can use the shell script from below to automatically set the quotaugidlimit based on the needs of the individual containers. Just setup a cronjob for it.
Script
#!/bin/bash # If one of these files does not exist then something # is really broken [ -d /etc/vz/conf ] || exit 1 # get all configured VEs FILES=/etc/vz/conf/*.conf # loop through all VEs for file in $FILES do STRING="" VALUE="" INT="" CONFFILE="" VEID="" USERC="" GROUPC="" TOTAL="" # source the config file . $file # check if quotaugidlimit is set if grep -q "QUOTAUGIDLIMIT" $file then # get current quotaugidlimit STRING=`grep "QUOTAUGIDLIMIT" $file` VALUE=${STRING##*QUOTAUGIDLIMIT=\"} INT=${VALUE%?} # check if quotaugidlimit is > 0 if [ ! $INT == 0 ]; then # get configfile name CONFFILE=`basename $file` VEID=${CONFFILE%.*} # run commands "inside" the VE USERC=`cat $VE_PRIVATE$VEID/etc/passwd | wc -l` GROUPC=`cat $VE_PRIVATE$VEID/etc/group | wc -l` TOTAL=$(($USERC + $GROUPC + 15)) # only change if current value is lower if [ $TOTAL -gt $INT ]; then # set the new quotaugidlimit for container vzctl set $VEID --quotaugidlimit $TOTAL --save echo "New quotaugidlimit set to $TOTAL for VEID $VEID\n" fi fi fi done
This will check for current users/groups count and increate the value by 15 - and set it as a new limit for the container.
