Hi, I want to create a file system with 16MB for data blocks and 256k for metadata blocks. Under filesystem version 13.01 (3.5.0.0) this worked just fine, even when upgrading GPFS later.
However, for a filesystem created with version 13.23 (3.5.0.7), if I specify both data and metadata block sizes, the metadata block size applies for both. If I do not specify metadata block size, the data block size (-B) is used for both. This has a detrimental impact on our metadataOnly NSDs, as they fill up pretty quickly. Are any of you aware of updates / bugs in GPFS that might help explain and alleviate this issue? Any hints would be appreciated. Regards, Asgeir
