CSIM Technical Notes

Transfer deleted accounts files to amanda

Move deleted user accounts files from banyan to amanda.

1. On banyan check the total size of all the deleted files:

   sudo du -shc /home/*/deleted
   

2. Login to amanda and become root.
3. If there is not enough space to copy the old accounts to /deleted on amanda, we need to make space:

   find /deleted -mtime +400w -delete
   

   This will remove any file older than 400 weeks (about 8 years).
   Start with 400 weeks and reduce by 50 weeks until there is enough space available.
   Do the same for /host/localhost/ada7/home.
   Note: we cannot check the disk space abailable on /host/localhost/ada7 because it is shared with Amanda backups, so we must do the same delete as for /deleted. (We can check the size of everything that is not home of the disk ada7.)
4. Delete ghost directories that have been left empty after removing older files:

   find /deleted -depth -type d -empty -delete
   

   Do the same for /host/localhost/ada7/home.
   
5. Go to the disk ada7:

   cd /host/localhost/ada7
   

6. Copy the deleted files from banyan:

   ssh on@banyan sudo -A tar cf - /home/\*/deleted | tar xfBp -
   

   On a non-graphic environment, you may use -S instead of -A but be aware that the password will show in clear on the screen.
7. Go to the deleted directoriy on the system disk:

   cd /deleted
   

8. Repeat the step 6.
9. Login on banyan and become root.
10. Go to the home directory:

    cd /home
    

11. Remove the deleted account files:

    rm -rf */deleted/*
