Bug Description

Error "stdin: fdopen failed: Invalid argument" while running lvreate, lvremove or lvs in a script run using nohup or scheduled in crontab

When running "/sbin/lvcreate -L10000M -s -n ZimbraBackup /dev/vg_opt-zimbra/lv_opt-zimbra", lvcreate returns these errors:
  stdin: fdopen failed: Invalid argument
  stdin: fclose failed: Invalid argument
  stdin: fdopen failed: Invalid argument

When running "/sbin/lvremove --force /dev/vg_opt-zimbra/ZimbraBackup", lvremove returns these errors:
  stdin: fdopen failed: Invalid argument
  stdin: fclose failed: Invalid argument
  stdin: fdopen failed: Invalid argument

Ubuntu versión is:
#lsb_release -a

# dpkg -l | grep lvm

In Ubuntu 16 it works fine, but in Ubuntu 14 it doesn't.

Is it a bug?

We run the script redirecting "/dev/null" to stdin for the script and now it works:
nohup ./backup_zimbra_lvm.sh </dev/null &
