That should remain # to be the case even if multiple levels of indirection # are introduced as we remove more and more devices. # # STRATEGY: # # 1. We create a file of size 128k and we save its contents # in a local variable. # 2. We set the limit of the maximum copied segment size of # removals to 32k, so during removal our 128k file will # be split to 4 blocks. # 3. We start removing disks and adding them back in a loop. # This way the file is moved around and introduces split # blocks. # 4. The loop itself tests that we don't have any problem # when removing many devices. Within the loop we test # that the files contents remain the same across transfers. # TMPDIR=${TMPDIR:-$TEST_BASE_DIR} log_must mkfile $(($MINVDEVSIZE * 2)) $TMPDIR/dsk1 log_must mkfile $(($MINVDEVSIZE * 2)) $TMPDIR/dsk2 DISKS="$TMPDIR/dsk1 $TMPDIR/dsk2" REMOVEDISK=$TMPDIR/dsk1 log_must default_setup_noexit "$DISKS" function cleanup { default_cleanup_noexit log_must rm -f $DISKS # reset REMOVE_MAX_SEGMENT to 1M set_tunable32 REMOVE_MAX_SEGMENT 1048576 } log_onexit cleanup # set REMOVE_MAX_SEGMENT to 32k log_must set_tunable32 REMOVE_MAX_SEGMENT 32768 log_must dd if=/dev/urandom of=$TESTDIR/$TESTFILE0 bs=128k count=1 FILE_CONTENTS=$(<$TESTDIR/$TESTFILE0) log_must [ "x$(<$TESTDIR/$TESTFILE0)" = "x$FILE_CONTENTS" ] for i in {1..10}; do log_must zpool remove $TESTPOOL $TMPDIR/dsk1 log_must wait_for_removal $TESTPOOL log_mustnot vdevs_in_pool $TESTPOOL $TMPDIR/dsk1 log_must zpool add $TESTPOOL $TMPDIR/dsk1 log_must zinject -a log_must dd if=$TESTDIR/$TESTFILE0 of=/dev/null log_must [ "x$(<$TESTDIR/$TESTFILE0)" = "x$FILE_CONTENTS" ] log_must zpool remove $TESTPOOL $TMPDIR/dsk2 log_must wait_for_removal $TESTPOOL log_mustnot vdevs_in_pool $TESTPOOL $TMPDIR/dsk2 log_must zpool add $TESTPOOL $TMPDIR/dsk2 log_must zinject -a log_must dd if=$TESTDIR/$TESTFILE0 of=/dev/null log_must [ "x$(<$TESTDIR/$TESTFILE0)" = "x$FILE_CONTENTS" ] done log_pass "File contents transferred completely from one disk to another."
