Hi Everyone,

We are using vnx7600 unified box in our environment. We have NAS vdm's configured and backups are configured as NDMP on EMC data domain. Now we have two different problem, one of nas file system has grown up to 10tb  and contains billions of logs files into it.

1) Backup are running very slow since since we expand the celerra pool with 2tb of lun and expand the file system with 200gb. Storage pool has 5tb space left and around 95% utilized. Backup has never got completed after that and we are not sure what caused this. The only change we made is as above I mentioned.

2) We are planning to split this fs on directory level. Plan is to create a new filesystem say live1 on same vdm and due to application dependency we need to migrate the sub-directory from older fs live to live1 and accordingly network team change will change the rules and windows team change the permission. Is there any migration approach we can follow to perform on storage end to get this done successful.

Eg. live/test/folder1/folder2 to live1/test/folder1/folder2

Any suggestion would be highly appreciated.
