Description
When a file is attaching and copying data from Lustre OSTs to PCC copy, the file is in PCC attaching state. New open and I/O on the same file will fallback to Lustre OSTs.
Once the file finished the PCC attach and valid cached on PCC backend, the new I/O for the fallback file handle is still issuing to Lustre OSTs.
In this case, we could reopen the PCC copy, and direct the I/O to PCC copy instead.
