This test ensures 29# that ZFS restarts the removal thread if the export fails 30# for some reason. 31# 32# STRATEGY: 33# 34# 1. Create a pool with one vdev and do some writes on it. 35# 2. Add a new vdev to the pool and start the removal of 36# the first vdev. 37# 3. Inject a fault in the pool and attempt to export (it 38# should fail). 39# 4. After the export fails ensure that the removal thread 40# was restarted and the process complete successfully. 41# 42 43 44function cleanup 45{ 46 zinject -c all 47 default_cleanup_noexit 48} 49 50function callback 51{ 52 # 53 # Inject an error so export fails after having just suspended 54 # the removal thread.
