How to check volume is mounted or not using python with a dynamic volume name
- by SR query
import subprocess
def volumeCheck(volume_name):
"""This function will check volume name is mounted or not.
"""
volume_name = raw_input('Enter volume name:')
volumeCheck(volume_name)
print 'volume_name=',volume_name
p = subprocess.Popen(['df', '-h'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
p1, err = p.communicate()
pattern = p1
if pattern.find(volume_name):
print 'volume found'
else:
print 'volume not found'
While running i always got wrong result "volume found".
