experience with FS-cache and cachefilesd (Paul Nendick)

Hi Paul and Mike,

Thanks for the replies

Paul:

What kind of workloads are you running on it? I suspect we have reasonably heavy workloads, though I should really benchmark it.

Mike:

yes, there seems to be quite a users out in the wild with similar problems. We're running it on 2.6.34 kernel, but I have tried kernel 3.1.7 with the same results.

Next step is to see if we can do without it if I can't find the cause

For what it's worth, FS_Cache/cachefilesd has been working a champ on some
   of our workstations here for about a year. We've seen no evidence of it
   affecting stability or introducing data corruption of any sort. This is on
   Ubuntu 10.04 with the stock builds of everything straight from the vendor
   repositories.

We haven't yet committed time to run through the numbers and conclude
   whether or not it's actually aided performance though. Anecdotal evidence
   has been largely positive.
