Cause
Veritas recommends limiting the number of files in a single VxFS directory to 100,000 files.
Resolution
To maximize VxFS performance, do not exceed 100,000 files in the same directory. This recommendation is applicable across all VxFS layout versions and Storage Foundation releases and has been documented in all Storage Foundation release notes.
As a workaround, divide the files into multiple directories, such that no single directory contains more than 100,000 files.
