All deltas past a freeze point are kept for -# replay and comparison later. Here is the flow: -# -# create an empty file system (FS) -# freeze FS -# run various user commands that create files, directories and ACLs -# copy FS to temporary location (COPY) -# unmount filesystem -# <at this stage FS is empty again and unfrozen, and the -# intent log contains a complete set of deltas to replay it> -# remount FS <which replays the intent log> -# compare FS against the COPY -# - -PATH=/usr/bin -PATH=$PATH:/usr/sbin -PATH=$PATH:/bin -PATH=$PATH:/sbin -export PATH - -# ==================================================================== -# SETUP -# ==================================================================== -CMD=$(basename "$0") -POOL=ziltestpool.$$ -DEVSIZE=${DEVSIZE-200m} -POOLDIR=/var/tmp -POOLFILE=$POOLDIR/ziltest_poolfile.$$ -SLOGFILE=$POOLDIR/ziltest_slog.$$ -FS=$POOL/fs -ROOT=/$FS -COPY=/var/tmp/${POOL} -KEEP=no - -cleanup() -{ - zfs destroy -rf $FS - echo "$CMD: pool I/O summary & status:" - echo "----------------------------------------------------" - zpool iostat $POOL - echo - zpool status $POOL - echo "----------------------------------------------------" - echo - zpool destroy -f $POOL - rm -rf $COPY - rm $POOLFILE $SLOGFILE -} - -bail() -{ - test $KEEP = no && cleanup - echo "$1" - exit 1 -} - -test $# -eq 0 || bail "usage: $CMD" - -# ==================================================================== -# PREP -# -# Create a pool using a file based vdev -# Create a destination for runtime copy of FS -# Freeze transaction syncing in the pool -# ==================================================================== -truncate -s "$DEVSIZE" $POOLFILE || bail "can't make $POOLFILE" -truncate -s "$DEVSIZE" $SLOGFILE || bail "can't make $SLOGFILE" -zpool create $POOL $POOLFILE log $SLOGFILE || bail "can't create pool -$POOL" -zpool list $POOL - -zfs set compression=on $POOL || bail "can't enable compression on $POOL" -zfs create $FS || bail "can't create $FS" -mkdir -p $COPY || bail "can't create $COPY" - -# -# This dd command works around an issue where ZIL records aren't created -# after freezing the pool unless a ZIL header already exists.
