Hi, This is something I was thinking while working on that buffer retry stuff. Currently, we have no way to force xfsaild to run, and I was wondering if somebody has any opinion if it would be useful to create a new xfsctl, to start xfsaild for debugging purposes, using xfs_io to trigger it. My specific use case is while testing the code I've been working on for the buffer retry stuff, where, I need to wait xfsaild to run to trigger the bug, adding a way to force it, in this case at least, would be useful for me, I could work on that, but only if somebody else can actually think this to be interesting, adding a new xfsctl just for 'me' does not sound worth the time :)
For the debugging purpose how about mkfs with a small size of log for instance 50MB and then use benchmark tools like fs_mark to fill the log quickly(write lots of small files instead of a single huge file), then the xfsaild will run frequently :) Thanks Shan Hai
Anybody else might have interest on it or maybe this is just a waste of time? Cheers
