the only way is to use fs_ckpt fsname -l -all which will give you a list of all checkpoints of a PFS and the percentage of savvol usage.  But thats it. COFW is working on blocklevel, not file level. You will not be able to see which data block is in the savvol or the data of the block. There is no command for this.  Sorry.
How can i find out which Data ist stored in savvol. I need a possibility to find out which data is in the SavVol and which is stored in the PFS. When a Data is modified the orginal one will be stored in SavVol (COFW), how can i find out which data ist stored in the savvol? Can you help me?
