I''m trying to get ceph working with decent performance (currently getting kb/second write performance!) and it seems that maybe the Debian wheezy kernel is just a bit too ancient. The 3.8 kernel from experimental works on bare metal, but when booting as dom0 under the xen hypervisor it crashes. I just figured out how to redirect xen output to my IPMI/BMC serial port and I see this:

Currently, when listing xattrs, kernel define XATTR_LIST_MAX as 65536 in include/linux/limits.h, so it can't handle too many xattrs. But with ocfs2 xattr tree, we actually have no limit for the number. And it will pollute the message with something like this when listing. (27738,0):ocfs2_iterate_xattr_buckets:3158 ERROR: status = -34 (27738,0):ocfs2_xattr_tree_list_index_block:3264 ERROR:

Hi, I am going to merge latest batch of the nullfs improvements into stable/9. This will bring up significant performance enchancements due to use of the shared locks for lookups if the lower layer supports it, much better caching on the nullfs layer, and proper handling of the text segments on the nullfs. Also, it should improve the error recovery and some corner cases with locking.

Hi - I''m trying to use plockstat to help identify any mutex contention issues we may have in our c++ app. >From the docs it would appear to be a very useful tool - unfortunately in practice this doesn''t bear out purely because the stack traces produced are limited to being 39/40 characters wide. In general this means that I''m not seeing ~75% of each stack symbol and

severity 200435 normal thanks I received this bug report from a Debian user.
