Symptoms
Customer is configured using QFS filesystems in a Solaris Cluster using Oracle RAC (Oracle Real Application Cluster). This configuration is referred to as SC-RAC.
They are reporting a performance issue when copying files to new storage recently configured to use new QFS filesystems to test with.
They reported testing using 'cp' to copy/write 1gb files to the new filesystems. They said it took roughly 90 seconds to copy 3 files of 1gb each. However, when they copied those same 3 files to their older filesystems, using their older storage, the copy completed within 9 seconds for 3gb. They reported that the delay/slowness was even greater when the file sizes were larger.
Changes
New QFS filesystems configured using a new storage array
