Just a quick update on this one for anyone interested;

Having left the script to take ownership and change permissions running in windows for over a week on one folder containing 22m files, it had not even gotten past the first 1 of 3160 root folders!!!!!!

So, with the aid of an ONTAP 9 simulator, we were able to rm –r –f from the systemshell.

You have to unlock the diag user, then “sudo rm –r –f /clust/svm/volume” but it works and works without requiring ownership or permission to the files. It’s fast too. (done nearly 140 root folders in an hour)

This isn’t ideal having to use the systemshell, but is the only way we have found to perform this task in a timely, reliable manor.

Kind Regards,

Chris.

Ok, so fastcopy isn’t really much faster than windows delete. However it does delete the “path too long” files which windows fails on.

Now I have permissions issues!

So I have put together a crude batchfile to take ownership with subinacl, set permissions with icacls, delete what it can with del and rmdir, then finish off the job with fastcopy.

set wrkfile=\\cifs_server\root_share\dead_share

subinacl.exe /file %wrkfile% /setowner=%username%

subinacl.exe /subdirectories %wrkfile%\*.* /setowner=%username%

ICACLS %wrkfile% /grant %username%:F /T

del /f /s /q %wrkfile%

rmdir /q /s %wrkfile%

FastCopy.exe /cmd=delete /no_confirm_del /no_confirm_stop %wrkfile%

But I’m still getting errors trying to take ownership of subfolders deep down in userprofiles.

Surely there has got to be an easier way??

systemshell –node a

cd /folder

rm –rf

Thanks Basil,

I do prefer the clone and delete option because I can control users access to the data. When I wish to perform the cutover I can remove the 7-Mode share from DFS, update the baseline with 7MTT and then bring the shares online from CDOT before updating the DFS share paths.

Then indeed I can perform the clean up behind the scenes as I am sharing a subfolder from each of the clones.

I would just like a more reliable \ faster way of deleting the folders and files… I have read reviews that FastCopy https://ipmsg.org/tools/fastcopy.html.en may be able to do this, so I will perform a test operation using that.

Kind Regards,

Chris.

Your clone and delete plan is likely your best option. It does indeed take forever but it's all behind the scenes assuming you are sharing the subfolder rather than the whole clone.

Hi all,

I am soon to be transitioning a large CIFS share (5tb) from 7-Mode to CDOT and during the migration I would like to use the opportunity to split the share into several more manageable volumes.

My initial thoughts were to use robocopy, but there are potentially permissions issues.

Another method I’m exploring is to use 7MTT to mirror the volume, then once complete, create flexclones, 1 for each of the shares I would like to split out. Then delete the no longer required data from each respective share and vol split before deleting the master.

Firstly, am I missing some simpler way of doing this? systemshell maybe?

Secondly, if not, then is there a quicker way of deleting 20m files from each of my 6 shares? Maybe an on-filer way of destroying the folders? So far using command line tools (del, rmdir) still take far too long.

Many Thanks in advance,

Chris.
