Just a thought - we made the default compression level in gfs2_edit savemeta to be -z 9, which means best compression level vs speed. If that caused a significant performance overhead then we could definitely reconsider the default setting, but also Support could advise customers with larger filesystems to use lower -z values when asking for metadata, before it's even fixed. Obviously the size of the metadata file will increase with faster compression levels so that will be a factor to consider. It would be interesting to see some performance comparisons between the -z levels. After evaluating this issue, there are no plans to address it further or fix it in an upcoming release. Therefore, it is being closed. If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened. |
