Update /etc/zfs/vdev_id.conf with scsidebug alias for a persistent path. 35# This creates keys ID_VDEV and ID_VDEV_PATH and set phys_path="scsidebug". 36# 2. Create a pool and set autoreplace=on (auto-replace is opt-in) 37# 3. Export the pool 38# 4. Wipe and offline the scsi_debug disk 39# 5. Import the pool with missing disk 40# 6. Re-online the wiped scsi_debug disk 41# 7. Verify ZED detects the new blank disk and replaces the missing vdev 42# 8. Verify that the scsi_debug disk was re-partitioned 43# 44# Creates a raidz1 zpool using persistent /dev/disk/by-vdev path names 45# (ie not /dev/sdc) 46# 47# Auto-replace is opt in, and matches by phys_path. 48# 49 50verify_runnable "both" 51 52if ! is_physical_device $DISKS; then 53 log_unsupported "Unsupported disks for this test." 54fi 55 56function cleanup 57{ 58 zpool status $TESTPOOL 59 destroy_pool $TESTPOOL 60 sed -i '/alias scsidebug/d' $VDEVID_CONF 61 unload_scsi_debug 62} 63 64log_assert "Testing automated auto-replace FMA test" 65log_onexit cleanup 66 67load_scsi_debug $SDSIZE $SDHOSTS $SDTGTS $SDLUNS '512b' 68SD=$(get_debug_device) 69SD_DEVICE_ID=$(get_persistent_disk_name $SD) 70SD_HOST=$(get_scsi_host $SD) 71 72# Register vdev_id alias for scsi_debug device to create a persistent path 73echo "alias scsidebug /dev/disk/by-id/$SD_DEVICE_ID" >>$VDEVID_CONF 74block_device_wait 75 76SD_DEVICE=$(udevadm info -q all -n $DEV_DSKDIR/$SD | \ 77 awk -F'=' '/ID_VDEV=/ {print $2; exit}') 78[ -z $SD_DEVICE ] && log_fail "vdev rule was not registered properly" 79 80log_must zpool events -c 81log_must zpool create -f $TESTPOOL raidz1 $SD_DEVICE $DISK1 $DISK2 $DISK3 82 83# Auto-replace is opt-in so need to set property 84log_must zpool set autoreplace=on $TESTPOOL 85 86# Add some data to the pool 87log_must zfs create $TESTPOOL/fs 88log_must fill_fs /$TESTPOOL/fs 4 100 4096 512 Z 89log_must zpool export $TESTPOOL 90 91# Record the partition UUID for later comparison 92part_uuid=$(udevadm info --query=property --property=ID_PART_TABLE_UUID \ 93 --value /dev/disk/by-id/$SD_DEVICE_ID) 94[[ -z "$part_uuid" ]] || log_note original disk GPT uuid ${part_uuid} 95 96# 97# Wipe and offline the disk 98# 99# Note that it is not enough to zero the disk to expunge the partitions. 100# You also need to inform the kernel (e.g., 'hdparm -z' or 'partprobe'). 101# 102# Using partprobe is overkill and hdparm is not as common as wipefs.
