Linux cannot recognize Korean‑named files that are migrated from EMC to NetApp
Applies to
- ONTAP 9
- NFSv4
- Data Migration
- Rsync
Issue
- During data migration from EMC Unity300 to NetApp C30 storage using rsync from a Linux server, files with Korean characters in their names that are created on AIX servers are visible on AIX (NFSv3 mount) but are not visible on Linux servers (NFSv4 mount).
- AIX server: This is the NFS client in the production environment(EMC Unity300)
- Linux server: This is the data migration server between the EMC Unity300 and the NetApp C30 storage system
- Changing the NetApp volume language from C.UTF‑8 to utf8mb4 does not resolve the issue
- Packet trace logs show NFSv4 OPEN and LOOKUP requests for problematic filenames returning NFS4ERR_INVAL
