similar to: [PATCH] fs, ocfs2: Move o2net_get_func_run_time 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.

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.

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.

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

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

Hi I'd like to know if OCFS2 1.4 on RHEL5 with the REDHAT latest kernel supports disk quotas, the xattr and acl. I could have done something wrong but only the acl seem to work. Apparently instead on FC12, where support is enabled in the kernel itself OCFS grep / boot / config * CONFIG_OCFS2_FS = m CONFIG_OCFS2_FS_O2CB = m CONFIG_OCFS2_FS_USERSPACE_CLUSTER = m # CONFIG_OCFS2_FS_STATS is

Hello, I am new on this list. I have installed Wine successfully on my Mandrake but i think i couldnot configuire is smoothly. Whatever i can run simple programs like WinZip and mIRC with it but complex programs like Macromedia Flash and Photoshop CS is not running. It says that required files were not found in the Adobe Hpotoshop CS folder. Re-install photoshop to restore these files. Flash also

Hello everyone Is there a function/command to simulate from "matrix variate normal distribution" in R. A follow up question would be is there a function/command to obtain the density, distribution and quantile function of "matrix variate normal distribution" in R. Wikipedia has a good description of "matrix variate normal distribution" which is also alternatively

Hello everyone I was wondering how would one simulate from a Normal Wishart Distribution in R. A normal inverted Wishart distribution is denoted by NIW (M,C,d,S), where X/(Sigma) ~ N( M,C,(Sigma) ) -> a matrix normal distribution, (Sigma) -> column dispersion matrix (Sigma) ~ IW (d,S) -> inverted Wishart distribution Thanks a lot !

Hello Everyone Both the MCMCpack and the bayesm libraries allow us to make draws from the Inverse Wishart distribution. But I wanted to find out how exactly is the Inverse Wishart distribution parameterized in these libraries. The reason I ask is the following: Now its generally standard to express Inverse Wishart as IW(0.5 * DOF,0.5* Scale). (DOF-> Degree of freedom, Scale -> Scale

Hello Everyone I have a dual-core Intel i3-370M processor and Windows 64 operating system. I have a 3GB RAM and my processor can support a maximum of 8GB RAM. I have virtual memory enabled on my computer. I am running a program in the 64 bit R which implements a MCMC on a large dataset and involves around 80000 iterations. The processor estimates that it will take around 1000 minutes to

Hello Everyone I have a MCMC loop to calculate a time varying hierarchical Bayesian structure. This requires me to use around 5-6 matrix inversions in the loop. I use cholesky and chol2inv for the matrix decomposition. Because of the data I am working with I am required to invert a 167 by 167 matrix twice in one iteration. I need to run the iteration for 10000 times, but I get the error

I'm running a bit late with the e-mail this time around, but I think that's ok since there really isn't any major new features here - the bulk of the Ocfs2 update is bug fixes, or cleanups. The same goes for configfs. The only two things that could be described as features would be: - Sunil has updated Ocfs2 to provide even more live cluster locking information via debugfs. - Joel

The only non-fix here is Joel's new configfs convenience macros, but nobody is using them yet, so I think the patch is safe. By the way, these patches (as usual) are all rebased on top of your latest tree. I think that since the vast majority of ocfs2 and configfs patches are self-contained and within a small area of the kernel that this should probably be fine. If you feel otherwise however,

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

Currently, o2net_accept_one() is allowed to accept a connection from listening node itself, such a fake connection will not be successfully established due to no handshake detected afterwards, and later end up with triggering connecting worker in a loop. We're going to fix this by treating such connection request as 'invalid', since we've got no chance of requesting connection
