* ocfs2: Add support for heartbeat=global mount optionSunil Mushran2010-10-071-14/+41
| | | | | | | Adds support for heartbeat=global mount option. It ensures that the heartbeat mode passed matches the one enabled on disk. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>
* ocfs2: Add an incompat feature flag OCFS2_FEATURE_INCOMPAT_CLUSTERINFOSunil Mushran2010-10-091-1/+3
| | | | | | | | | | | | | | | OCFS2_FEATURE_INCOMPAT_CLUSTERINFO allows us to use sb->s_cluster_info for both userspace and o2cb cluster stacks. It also allows us to extend cluster info to include stack flags. This patch also adds stackflags to sb->s_clusterinfo. It also introduces a clusterinfo flag OCFS2_CLUSTER_O2CB_GLOBAL_HEARTBEAT to denote the enabled global heartbeat mode. This incompat flag can be set/cleared using tunefs.ocfs2 --fs-features. The clusterinfo flag is set/cleared using tunefs.ocfs2 --update-cluster-stack. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>

|/ | | | | | | | | | | | | ocfs2 sometimes needs to block signals around dlm operations, but it currently does it with sigprocmask(). Even worse, it's checking the error code of sigprocmask(). The in-kernel sigprocmask() can only error if you get the SIG_* argument wrong. We don't. Wrap the sigprocmask() calls with ocfs2_[un]block_signals().

* ocfs2: increase the default size of local alloc windowsMark Fasheh2010-05-051-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have observed that the current size of 8M gives us pretty poor fragmentation on multi-threaded workloads which do lots of writes. Generally, I can increase the size of local alloc windows and observe a marked decrease in fragmentation, even up and beyond window sizes of 512 megabytes. This makes sense for a couple reasons - larger local alloc means more room for reservation windows. On multi-node workloads the larger local alloc helps as well because we don't have to do window slides as often. Also, I removed the OCFS2_DEFAULT_LOCAL_ALLOC_SIZE constant as it is no longer used and the comment above it was out of date. To test fragmentation, I used a workload which launched 4 threads that did 4k writes into a series of about 140 alternating files. With resv_level=2, and a 4k/4k file system I observed the following average fragmentation for various localalloc= parameters: localalloc= avg. fragmentation 8 48 32 16 64 10 120 7 On larger cluster sizes, the difference is more dramatic. The new default size top out at 256M, which we'll only get for cluster sizes of 32K and above. Signed-off-by: Mark Fasheh <mfasheh@suse.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>
* ocfs2: clean up localalloc mount option size parsingMark Fasheh2010-05-051-5/+5
| | | | | | | | | | | | | | | | | This patch pulls the local alloc sizing code into localalloc.c and provides a callout to it from ocfs2_fill_super(). Behavior is essentially unchanged except that I correctly calculate the maximum local alloc size. The old code in ocfs2_parse_options() calculated the max size as: ocfs2_local_alloc_size(sb) * 8 which is correct, in bits. Unfortunately though the option passed in is in megabytes. Ultimately, this bug made no real difference - the shrink code would catch a too-large size and bring it down to something reasonable. Still, it's less than efficient as-is.

* ocfs2: allocation reservationsMark Fasheh2010-05-051-0/+25
| | | | | | | | | | | | | | | | | | | | This patch improves Ocfs2 allocation policy by allowing an inode to reserve a portion of the local alloc bitmap for itself. The reserved portion (allocation window) is advisory in that other allocation windows might steal it if the local alloc bitmap becomes full. Otherwise, the reservations are honored and guaranteed to be free. When the local alloc window is moved to a different portion of the bitmap, existing reservations are discarded. Reservation windows are represented internally by a red-black tree. Within that tree, each node represents the reservation window of one inode. An LRU of active reservations is also maintained. When new data is written, we allocate it from the inodes window. When all bits in a window are exhausted, we allocate a new one as close to the previous one as possible. Should we not find free space, an existing reservation is pulled off the LRU and cannibalized. Signed-off-by: Mark Fasheh <mfasheh@suse.com>

This causes problems during umount because ocfs2_wq can drop references to inodes while they are being invalidated by invalidate_inodes() causing all sorts of nasty things (invalidate_inodes() ending in an infinite loop, "Busy inodes after umount" messages etc.). We fix the problem by stopping ocfs2_wq from doing any further releasing of inode references on the superblock being unmounted, wait until it finishes the current round of releasing and finally cleaning up all the references in dentry_lock_list from ocfs2_put_super().
