Symptoms

Below file was initially in ASM diskgroup and then moved to OS file system ,Now when trying to place it back in ASM diskgroup it fails to copy entire file as below.

 

$ ls -l
-rw-r----- 1 oracle oinstall 3758096392192 Apr 5 16:48 epic_reporting.265.934616757==>3.7 TB

Tried to copy back with new ASM installation, plenty of room in ASM disk group:

ASMCMD> cp /oradump/savepdb/epic_reporting.265.934616757 epic_reporting
copying /oradump/savepdb/epic_reporting.265.934616757 -> +data/sanford2015/4744C6696FF93F4EE053ABC0080A86C9/datafile/epic_reporting
ASMCMD>

But with no error messages, doesn't copy entire file to ASM:

ASMCMD> ls -s
Block_Size Blocks Bytes Space Name
  8192 190316545 1559073136640 1559081517056 epic_reporting => +DATA/ASM/DATAFILE/epic_reporting.262.940576351==>1.6 TB around only copied


Deleted partial file, running again produces exact same result. No messages in ASM alert log or elsewhere.
