I want to create a file system with 16MB for data blocks and 256k for
metadata blocks. Under filesystem version 13.01 (22.214.171.124) this worked just
fine, even when upgrading GPFS later.
However, for a filesystem created with version 13.23 (126.96.36.199), 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
Are any of you aware of updates / bugs in GPFS that might help explain and
alleviate this issue? Any hints would be appreciated.
