Create a pool 27# 2. Remove a disk. 28# 3. Write a test file to the pool and calculate its checksum. 29# 4. Execute scrub. 30# 5. "Plug back" disk. 31# 6. Reopen a pool. 32# 7. Check if scrub scan is replaced by resilver. 33# 8. Put another device offline and check if the test file checksum is correct. 34# 35# NOTES: 36# A 250ms delay is added to make sure that the scrub is running while 37# the reopen kicks the resilver. 38# 39 40verify_runnable "global" 41 42function cleanup 43{ 44 log_must zinject -c all 45 # bring back removed disk online for further tests 46 insert_disk $REMOVED_DISK $scsi_host 47 poolexists $TESTPOOL && destroy_pool $TESTPOOL 48} 49 50log_assert "Testing zpool reopen with pool name as argument" 51log_onexit cleanup 52 53set_removed_disk 54scsi_host=$(get_scsi_host $REMOVED_DISK) 55 56# 1.
