similar to: [PATCH net-next v2 12/17] ocfs2: Use sendmsg(MSG_SPLICE_PAGES) rather than sendpage()

Fix ocfs2 to use the page fragment allocator rather than kzalloc in order to allocate the buffers for the handshake message and keepalive request and reply messages. Switch from using sendpage() to using sendmsg() + MSG_SPLICE_PAGES so that sendpage can be phased out.

This patch separates o2net and o2quo from knowing about one another as much as possible. This is the first in a series of patches that will allow userspace cluster interaction. Quorum is separated out first, and will ultimately only be associated with the disk heartbeat as a separate module. To do so, this patch performs the following changes: * o2hb_notify() is added to handle injection of

This is a forward port for net_proc.c from 1.2.

This fix modifies o2net layer behavior which seems to trigger some DLM race issues during umount/evictions that needs to be fixed as well. I am working on the dlm issues but meanwhile please review this patch. Thanks, --Srini

Hello everyone, once again. We are running into a problem, which has shown now 2 times, possible 3 (once the systems looked different.) The environment is 6 HP DL360/380 g5 servers with eth0 being the public interface, eth1 and bond0 (eth2 and eth3) used for clusterware and bond0 also used for OCFS2. The bond0 interface is in active/passive mode. There are no network errors counters showing and

Now that ->sendpage() has been removed, MSG_SENDPAGE_NOTLAST can be cleaned up. Things were converted to use MSG_MORE instead, but the protocol sendpage stubs still convert MSG_SENDPAGE_NOTLAST to MSG_MORE, which is now unnecessary.

Is sendpage or some other alphanumeric paging program available from one of the repos for CentOS 5? I've checked rpmforge and epel. I just wanted to check to see if it might be available somewhere else before I resort to building from source. -- Bowie

Commit 0f475b2abed6cbccee1da20a0bef2895eb2a0edd (ocfs2/net: Silence build warnings) made sense as far as it fixed compile warnings, but it was not required that it made the functions global.

When CONFIG_DEBUG_FS=y and CONFIG_OCFS2_FS_STATS=n, we get the following warning: fs/ocfs2/cluster/tcp.c:213:16: warning: ?o2net_get_func_run_time? defined but not used Since o2net_get_func_run_time is only called from o2net_update_recv_stats, so move it under CONFIG_OCFS2_FS_STATS.

Currently, o2net connects to a node on hb_up and disconnects on hb_down and net timeout. It disconnects on net timeout is ok, but it should attempt to reconnect back. This is because sometimes nodes get overloaded enough that the network connection breaks but the disk hb does not. And if we get into that situation, we either fence (unnecessarily) or wait for its disk hb to die (and sometimes hang

Modification from V1 to V2: 1. Use atomic ops instead of spin_lock in timer. 2. Add some comments when querying connect_expired work. These comments are copied form Zach's mail.;) Currently, o2net connects to a node on hb_up and disconnects on hb_down and net timeout.

The following series of patches comprises the bulk of our outstanding changes for Ocfs2. Aside from the usual set of cleanups and fixes that were inappropriate for 2.6.25, there are a few highlights: The '/sys/o2cb' directory has been moved to '/sys/fs/o2cb'. The new location meshes better with modern sysfs layout. A symbolic link has been placed in the old location so as to

From: Tom Rix <trix at redhat.com> This is a upcoming change to clean up a new warning treewide. I am wondering if the change could be one mega patch (see below) or normal patch per file about 100 patches or somewhere half way by collecting early acks. clang has a number of useful, new warnings see
