Hi Everybody,
From the last one week so many mails are exchanged on this topic.
I have also one similar issue like this. I will appreciate if any one helps
me on this.
I have an IO test tool, which writes the data and reads the data and then
compare the read data with write data. If read data and write data are same
then there is no CORRUIPTION else there is a CORRUPTION.
File data may corrupt because of any reasons and one possible reason is file
system cache. If file system cache have issues, it will give wrong data (wrong
data means the actual data on the disk and the data that read call return to
the application are not match) to user applications.
When there is a CORRUPTION, to check file system cache issues, my application
bypass the file system cache and then reads (Re-read) the data from the same
file and then compare the re-read data with write data.
Tell me, is there a way to skip ZFS file system cache or tell me is there a
way to do direct IO on ZFS file system?
Regards
Masthan D
