Hello Chris,
Is there any way to tell fio to insert a periodically sync... not sync
every I/O, but every N I/O's, or maybe on some period?
fsync=int If writing to a file, issue a sync of the dirty data
for every number of blocks given. For example, if you give
32 as a parameter, fio will sync the file for every 32
writes issued. If fio is using non-buffered io, we may
not sync the file. The exception is the sg io engine, which
synchronizes the disk cache anyway.
This should help you.
Thanks,
-Guru
