Unlike quotas however there should be no restrictions 40# on accessing space outside of the limits of the reservation (if the 41# space is available in the pool). Verify that in a filesystem with a 42# reservation set that its possible to create files both within the 43# reserved space and also outside. 44# 45# STRATEGY: 46# 1) Create a filesystem 47# 2) Get the space used and available in the pool 48# 3) Set a reservation on the filesystem 49# 4) Verify can write a file that is bigger than the reserved space 50# 51# i.e. we start writing within the reserved region and then continue 52# for 20MB outside it. 53# 54 55verify_runnable "both" 56 57function cleanup 58{ 59 [[ -e $TESTDIR/$TESTFILE1 ]] && log_must rm -rf $TESTDIR/$TESTFILE1 60 log_must zfs set reservation=none $TESTPOOL/$TESTFS 61} 62 63log_onexit cleanup 64 65log_assert "Verify can create files both inside and outside reserved areas" 66 67space_used=`get_prop used $TESTPOOL` 68 69log_must zfs set reservation=$RESV_SIZE $TESTPOOL/$TESTFS 70 71# 72# Calculate how many writes of BLOCK_SIZE it would take to fill 73# up RESV_SIZE + 20971520 (20 MB). 74# 75fill_size=`expr $RESV_SIZE + 20971520` 76write_count=`expr $fill_size / $BLOCK_SIZE` 77 78log_must file_write -o create -f $TESTDIR/$TESTFILE1 -b $BLOCK_SIZE \ 79 -c $write_count -d 0 80 81log_pass "Able to create files inside and outside reserved area" 82
