[LU-16455] recovery-small test_139: failed to set up loop device: No such file or directory

Thu, 19 Jan 2023 20:54:49 +0000

mds device calculated before stop () can not be used after stop() because of a device-mapper device is removed and facet device is restored:

  stop () ->
    elif dm_flakey_supported $facet; then
      if [[ -n ${!failover_host} &&
               ${!failover_host} != ${!host} ]]
         dm_cleanup_dev $facet ->
               unexport_dm_dev $facet

Without the proposed fix the test_139 fails on failover setup:

  losetup: /dev/mapper/mds1_flakey: failed to set up loop device:
    No such file or directory

To reproduce the failure just run:

  sh llmountcleanup.sh
  ONLY=139 sh recovery-small.sh

on failover setup where mds1_HOST != mds1failover_HOST
