GPFS supports the dirsync mount option

Our bussinuss architure is like FuseClient --> FileServer(GPFS NativeClient)-->GPFS.


IBM GPFS does not support dirsync mount option in Linux. GPFS Native Client will save the dir meta changes(create/mknod/link/unlink/rename...) in cache. The changes will be lost if mmfsd daemon crush or node fails before the cache has been flushed to GPFS(~3s). We need to call fsync after each dir chagnes(create/mknod/link/unlink/rename ...) and the create/remove latency increase from 500us to about 10~15ms and the IOPS degrade to 1/10. This is too bad for small file creation & deletion. We need GPFS supporting dirsync to avoid losing dir meta changes from mmfsd crushing or node failure and degrade the performance as little as possible.


The performance of AI-Traning online service is poor because of this issue. We hope this issue will be fixed as soon as possible.
