      If we have the following SAs:

      FS ROOT ACCESSPOINT VO
      TESTERSEUEMIEU_FS /storage/testers.eu-emi.eu /testers.eu-emi.eu testers.eu-emi.eu
      VIANELLO_FS /storage/vianello /testers.eu-emi.eu/vianello testers.eu-emi.eu

      on two hosts:

      • StoRM 1.11.2 = omii004-vm03
      • StoRM 1.11.3 = omii004-vm02

      with the following file on both hosts:

      1. touch /storage/vianello/sono_in_vianello.txt
      2. chown -R storm:storm /storage/vianello/*

      launch:

      lcg-ls -Dsrmv2 -b -l 'srm://omii004-vm03.cnaf.infn.it:8444/srm/managerv2?SFN=/testers.eu-emi.eu/vianello
/testers.eu-emi.eu/vianello: [SE][Ls][SRM_INVALID_PATH] No such file or directory

lcg-ls -Dsrmv2 -b -l 'srm://omii004-vm02.cnaf.infn.it:8444/srm/managerv2?SFN=/testers.eu-emi.eu/vianello
/testers.eu-emi.eu/vianello: [SE][Ls][SRM_INVALID_PATH] No such file or directory

      It retrieves SRM_INVALID_PATH because the mappend VFS is TESTERSEUEMIEU_FS instead of VIANELLO_FS. In fact, when the stfn doesn't end with a slash the last segment is removed before computing the mapped VFS. And this is the problem.

      Using the ending slash all works:

      $ lcg-ls -Dsrmv2 -b -l 'srm://omii004-vm03.cnaf.infn.it:8444/srm/managerv2?SFN=/testers.eu-emi.eu/vianello/'
-r--------   1     2     2       0               ONLINE /testers.eu-emi.eu/vianello/sono_in_vianello.txt

$ lcg-ls -Dsrmv2 -b -l 'srm://omii004-vm02.cnaf.infn.it:8444/srm/managerv2?SFN=/testers.eu-emi.eu/vianello/'
-r--------   1     2     2       0               ONLINE /testers.eu-emi.eu/vianello/sono_in_vianello.txt

      If we create a directory named vianello into testers.eu-emi.eu and a test file as follow:

      # touch /storage/testers.eu-emi.eu/vianello/sono_in_testerseuemieu.txt
# chown -R storm:storm /storage/testers.eu-emi.eu/*

      the test doesn't fail but:

      [vianello@omii006-vm02 ~]$ lcg-ls -Dsrmv2 -b -l 'srm://omii004-vm02.cnaf.infn.it:8444/srm/managerv2?SFN=/testers.eu-emi.eu/vianello'
-r--------   1     2     2       0               ONLINE /testers.eu-emi.eu/vianello/sono_in_testerseuemieu.txt
[vianello@omii006-vm02 ~]$ lcg-ls -Dsrmv2 -b -l 'srm://omii004-vm03.cnaf.infn.it:8444/srm/managerv2?SFN=/testers.eu-emi.eu/vianello'
-r--------   1     2     2       0               ONLINE /testers.eu-emi.eu/vianello/sono_in_testerseuemieu.txt

      the mapped VFS is wrong!
