* write-behind aggregate-size related changesRaghavendra G2009-04-161-15/+76
| | | | | | | | | | | This patch brings in following changes: 1. make aggregate-size as non-configurable and make it to be equal to maximum iobuf size. 2. best effort to write data in chunks of length as close to aggregate-size as possible but not greater than aggregate-size, since aggregate-size is made equal to Maximum size of iobuf.

* io-threads: Reduce default min and max threadsShehjar Tikoo2009-04-101-2/+2
| | | | | | | | Going by the memory usage for each threads, it is prudent to have lower number of threads by default and let users who understand the memory consequences increase the thread count for themselves. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* io-threads: Use non-default thread stack sizeShehjar Tikoo2009-04-102-1/+27
| | | | | | | | The default stack size on Linux is around 8 MiB for each thread. This is clearly too high for our purpose. This commit reduces the stack size down to 1 MiB. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* io-threads: Refactor un-ordered worker exit pathShehjar Tikoo2009-04-081-33/+17
| | | | | | | This is being done for the same reason as the previous refactoring for ordered threads. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* io-threads: Refactor ordered worker exit pathShehjar Tikoo2009-04-081-34/+25
| | | | | | | | | | | | | | This patch re-factors the exit path of an ordered worker on a time-out. Earlier we're checking for exit permission in such a way that required us to release and acquire the worker lock a second time in the worker loop opening a window wherein a new request could've been appended to the request queue. This patch makes the decision to exit while still holding on to the worker lock. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>

* io-threads: Sanity check worker thread idxShehjar Tikoo2009-04-061-20/+62
| | | | | | | | This patch adds sanity check for the ordered worker thread index returned from the inode's context. If the index is corrupted we STACK_UNWIND with ECANCELED. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* io-threads: Support autoscaling volfile optionsShehjar Tikoo2009-04-022-24/+104
| | | | | | | | | | | | | | | | | This commit finally makes the autoscaling feature visible to the user. Know that we're now using two separate thread-pools, one for data requests, called ordered thread-pool in io-threads, and the other for meta-data requests, called un-ordered thread-pool. We do not expose this information to the user to keep io-threads simple. Consequently, when the user specifies a min-threads and max-threads value, the number of threads assigned to each pool is equal, i.e. both pools start with their min threads set to half of the option "min-threads" and both scale up their threads at most up to half of option "max-threads". Volfile options will be added to the wiki and user-guide. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>

* io-threads: Allow scaling to be switched offShehjar Tikoo2009-04-022-11/+73
| | | | | | | | The default is also to provide no scaling. For both, ordered and unordered request pools, when scaling is off, we maintain atleast the minimum number of threads specified in the volfile. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* io-threads: Add ordered threadpool state and codeShehjar Tikoo2009-04-022-58/+182
| | | | | | | | | | | Now we have the remaining fops going through the ordered thread-pool. To route a request through ordered thread, we use iot_schedule_ordered(..) and the worker thread for ordered requests is iot_worker_ordered(..) Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* io-threads: Add un-ordered thread-pool.Shehjar Tikoo2009-04-022-98/+334
| | | | | | | | | | | | | | | | | | This commit adds everything needed to: a. Get un-ordered request going through the un-ordered thread-pool. This happens through, the iot_schedule_unordered(..). The unordered thread-pool consists of thread running the iot_worker_unordered(..) function. b. Make threads in the un-ordered thread pool start-up and exit depending on the thread state. Note that at this point the requests that need ordering are still going through iot_schedule(..). Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* io-threads: Classify requests for threadpool typeShehjar Tikoo2009-04-021-26/+33
| | | | | | | | | | | | | | | | | New io-threads will serve requests through two separate threadpools. One thread pool for requests that must be ordered on a file that is open. so that the server can process the requests in the order they were entered in the requests queue, and not in the order the io-thread is able to send a request, which in turn is determined by how the thread gets scheduled. This can also be called the data-intensive ops thread pool. Second thread-pool for requests that dont care about ordering, i.e. requests like lookup, open, create, mkdir, etc. Signed-off-by: Anand V.
