Update /etc/zfs/vdev_id.conf with scsidebug alias for a persistent path. 37# This creates keys ID_VDEV and ID_VDEV_PATH and set phys_path="scsidebug". 38# 2. Create a pool and set autoreplace=on (auto-replace is opt-in) 39# 3. Export the pool 40# 4. Wipe and offline the scsi_debug disk 41# 5. Import the pool with missing disk 42# 6. Re-online the wiped scsi_debug disk with a new serial number 43# 7. Verify ZED detects the new blank disk and replaces the missing vdev 44# 8. Verify that the scsi_debug disk was re-partitioned 45# 46# Creates a raidz1 zpool using persistent /dev/disk/by-id path names 47# 48# Auto-replace is opt in, and matches by phys_path. 49# 50 51verify_runnable "both" 52 53if ! is_physical_device $DISKS; then 54 log_unsupported "Unsupported disks for this test." 55fi 56 57function cleanup 58{ 59 zpool status $TESTPOOL 60 destroy_pool $TESTPOOL 61 sed -i '/alias scsidebug/d' $VDEVID_CONF 62 unload_scsi_debug 63} 64 65# 66# Wait until a vdev transitions to its replacement vdev 67# 68# Return 0 when vdev reaches expected state, 1 on timeout. 69# 70# Note: index +2 is to skip over root and raidz-0 vdevs 71# 72function wait_vdev_online # pool index oldguid timeout 73{ 74 typeset pool=$1 75 typeset -i index=$2+2 76 typeset guid=$3 77 typeset timeout=${4:-60} 78 typeset -i i=0 79 80 while [[ $i -lt $timeout ]]; do 81 vdev_guids=( $(zpool get -H -o value guid $pool all-vdevs) ) 82 83 if [ "${vdev_guids[$index]}" != "${guid}" ]; then 84 log_note "new vdev[$((index-2))]: ${vdev_guids[$index]}, replacing ${guid}" 85 return 0 86 fi 87 88 i=$((i+1)) 89 sleep 1 90 done 91 92 return 1 93} 94log_assert "automated auto-replace with by-id paths" 95log_onexit cleanup 96 97load_scsi_debug $SDSIZE $SDHOSTS $SDTGTS $SDLUNS '512b' 98SD=$(get_debug_device) 99SD_DEVICE_ID=$(get_persistent_disk_name $SD) 100SD_HOST=$(get_scsi_host $SD) 101 102# Register vdev_id alias for scsi_debug device to create a persistent path 103echo "alias scsidebug /dev/disk/by-id/$SD_DEVICE_ID" >>$VDEVID_CONF 104block_device_wait 105 106SD_DEVICE=$(udevadm info -q all -n $DEV_DSKDIR/$SD | \ 107 awk -F'=' '/ID_VDEV=/ {print $2; exit}') 108[ -z $SD_DEVICE ] && log_fail "vdev rule was not registered properly" 109 110log_must zpool events -c 111log_must zpool create -f $TESTPOOL raidz1 $SD_DEVICE_ID $DISK1 $DISK2 $DISK3 112 113vdev_guid=$(zpool get guid -H -o value $TESTPOOL $SD_DEVICE_ID) 114log_note original vdev guid ${vdev_guid} 115 116# Auto-replace is opt-in so need to set property 117log_must zpool set autoreplace=on $TESTPOOL 118 119# Add some data to the pool 120log_must zfs create $TESTPOOL/fs 121log_must fill_fs /$TESTPOOL/fs 4 100 4096 512 Z 122log_must zpool export $TESTPOOL 123 124# Record the partition UUID for later comparison 125part_uuid=$(udevadm info --query=property --property=ID_PART_TABLE_UUID \ 126 --value /dev/disk/by-id/$SD_DEVICE_ID) 127[[ -z "$part_uuid" ]] || log_note original disk GPT uuid ${part_uuid} 128 129# 130# Wipe and offline the disk 131# 132# Note that it is not enough to zero the disk to expunge the partitions. 133# You also need to inform the kernel (e.g., 'hdparm -z' or 'partprobe'). 134# 135# Using partprobe is overkill and hdparm is not as common as wipefs.
