 +**Update: Transfers directly from mounted diskpacks have significantly higher rates of failure. Staging data to RAID is strongly recommended!**
 +
 +**Update: The mark5B upgrade to SDK9.2 has adversely affected fuseMk5 performance. It is not uncommon for the program to crash, sometimes with kernel panic during copy operations. A workaround script using DIMino has been kludged together and is in ~oper/​recovery/​ but is still in development.**

 +It is also possible (and preferable) to export the data onto a RAID first. Currently, there are five RAIDS which can be used for temporary storage at Hobart - Vortex, Cornucopia, Jupiter (which contains two separate RAIDS of 6 and 12 TB) and Magilla. These can be NFS mounted on the mk5 machine with <​code>​mount vortex.phys.utas.edu.au:/​exports/​vortex_internal/​ /​mnt/​vortex</​code>​ (as root). Once mounted the data can be copied with <​code>​cp /​mnt/​diskpack/​r1485* /​mnt/​vortex/​r1485hb/</​code>​. 
 + 
 +Once fully copied, please check the data has not been corrupted in the transfer. ssh into the NFS host as observer and run <​code>​./​directory2list /​exports/​vortex_internal/​r1485hb Mark5B-256-16-1</​code>​ . The output to the screen will be the list of all the scans with the start mjd/time and a summary indicating if problems were found. If bad scans are found, a summary at the end will warn you, and list of bad scans will be made available. 
 + 
 +After a transfer to Bonn completes, you should run <​code>​directory2filelist /​data3/​r1/​hobart12/​r1485/​ Mark5B-256-16-1</​code>​ to check for errors in transmission. ​
