[Pvfs2-users] PVFS2 over SSD page allocation error

Thanks, Phil and Becky for your suggestions,

I did change the trove method to direct-io  and tried. It definitely seems
to be better compared to alt-aio option which I had Initially. I did some
stress testing on the file system after restarting. I did not see the same
error so far which  is good. Although, I did I see once  something like
this in the server log. But I was not able to reproduce it. Unless this is
something serious, I think that solution resolved the issue.

[E 02/15 12:15] trove_write_callback_fn: I/O error occurred
