Hi, In my small file test, 3 types of volume are created in same GlusterFS Cluster (4 nodes)
- Distritubed - Distributed Replicated - Distributed Striped 10 million small files (8 byte) create and search each test cycle life Nodes info : - OS : CentOS 6.6 64bit - RAM : 64GB - HDD : 4TB, 7200RPM, SAS *6 RAID 0 - FileSystem : XFS, BS=4K Problem : It occur when file reach ≒200 million (sum of 3 volumes) files created speed drop from ≒1500 to ≒100 Though the speed of creation become slow but search speed and throughput still good Seems each types of volume have same problem, I don't know what cause this problem.. Workaround : I try to create new volume ( Distributed | Distributed Replicated | Distributed Striped ), mount it, problem solved! But the old volume write speed still sad.. I'd try to increase below volume setting, but don't work at all - performance.cache-size - performance.io-thread-count I didn't enable the volume qouta option. Does glusterfs volume have some kind of limitation of file creation? Regards Nosa Hu,
