Find VM’s older than N days to free up disk space
I wrote a Python 2.6 script to find and list VM’s older than 90 days on my Windows workstation, so that I could compress them, move them to a 1TB drive attached to my machine, or to a file server, or delete them.
find_old_vms is a tool to find and list old VM’s (vmdk’s, vhd’s) on your hard drives that are older than a given number of days.
Usage: find_old_vms in_this_directory_tree older_than_days
Example: find_old_vms “c:\\” 90
Download for Windows XP, 2003, and Linux. The script uses atime (latest file access time), which is not supported on Windows Vista and Windows 7.
# # NOTE: This script uses atime - the last access time for deciding whether a VM # **** file is a candidate. On Windows XP, atime is updated every hour, whereas, # Windows Vista and Windows 7 do not provide an atime. import os, sys, glob, time # dtroot is the pathname for a node in a directory tree # age is the number of days for which a file has not been accessed # size in bytes is the maximum size of a file def scan(dtroot, age, size): """ scan <dir> scans the <dir> on host for virtual images """ filecount = 0 wctime = time.time(); # get current time for root, subdirs, files in os.walk(dtroot): # Build a list of filenames that have a suffix vmd* or vhd* vfiles = glob.glob(os.path.join(root,"*.v[mh]d*")) for f in vfiles: atime = os.path.getatime(f) elapsed_time = (wctime - atime)/(60*60*24) if elapsed_time > age: filecount = filecount + 1 print f, " last accessed ", int(elapsed_time), " days ago\n", if __name__ == "__main__": import sys # User asked for help if sys.argv == '?': print "\nfind_old_vms in_this_directory_tree older_then_days\n", print "Find all files with the suffix .v[mh]d* that have not been accessed since older_than_days", print "through a recusrive descent starting from the root in_this_directory_tree", sys.exit() # Validate that the first argument in_this_directory_tree is a valid path if not os.path.exists(sys.argv): print sys.argv, " is not a valid directory. Please provide another", sys.exit() # Arbitrarily limit search to 10 years invalid_age = 0 if int(sys.argv) < 1: invalid_age = 1 elif int(sys.argv) > 3650: invalid_age = 1 if invalid_age == 1: print sys.argv, " is invalid. Please provide between 1 and 3650 days", sys.exit() scan(sys.argv, int(sys.argv), 0)
If you remove the restriction of searching for vImh]d* files, it will help you find other older files as well. I will appreciate your feedback.
