Hi I am hitting this Warning reproducible, the workload is a ceph osd, kernel ist 3.1.0-rc5.

Hi everyone, This patchset is the latest approach I''m using for the Ceph storage daemon to keep track of which data has safely committed to disk. The basic idea is to not use the (problematic) user transaction ioctls at all. Instead, the daemon quiesces its own write requests, initiates an async snapshot, and then continues. The snapshot approach is nice because it provides rollback.

Since we do not want to delay the async transaction commit, we should use common work, not delayed work.

Hi list This happened when running an iozone test over ceph, it was doing lots of random reads. I have no idea how to properly interpret this, I should find it out. Let me know if you need something else. Thanks! [69003.803272] ------------[ cut here ]------------ [69003.807987] kernel BUG at fs/btrfs/inode.c:6230!

Hi Chris, This is the extent of my current queue of Btrfs snapshot/subvol/commit stuff. Most of these were posted several months ago. Can be sent upstream during this merge window? Not having this functionality is becoming a bit of a roadblock for our efforts to keep the Ceph data in a consistent state. These patches are also available from

I do not mean to be argumentative, but I have to admit a little frustration with Gluster. I know an enormous emount of effort has gone into this product, and I just can't believe that with all the effort behind it and so many people using it, it could be so fragile. So here goes. Perhaps someone here can point to the error of my ways. I really want this to work because it would be ideal

Hello, I''m seeing a lot of warnings in dmesg with a BTRFS filesystem. I''m using the 3.1 kernel, I found a patch for these warnings ( http://marc.info/?l=linux-btrfs&m=131547325515336&w=2) <http://marc.info/?l=linux-btrfs&m=131547325515336&w=2>, but that patch has already been included in 3.1. Are there any other patches I can try? I''m using

After running ceph on XFS for some time, I decided to try btrfs again. Performance with the current "for-linux-min" branch and big metadata is much better. The only problem (?) I''m still seeing is a warning that seems to occur from time to time: [87703.784552] ------------[ cut here ]------------ [87703.789759] WARNING: at fs/btrfs/inode.c:2103

Hi guys, I''m getting this kernel oops when using openSuSE 10.1 XEN kernel on dom0. When this happens, linux load average starts incrising dramatically and after some minutes, any application that need access to a file starts to hang. This seems to happen when there is some amount of network traffic (this machine is a samba file server). For now, I have no virtual machines initialized.

I'm not really being too lucky in the last days. After trying to compile cdr_mysql with no success, I am switching to cdr_odbc. I have installed unixODBC, iODBC and MyODBC correctly, I am even able to make queries with isql. But when trying to "make" in the cdr directory of the latest CVS, that's what I get: # cd /usr/src/asterisk/cdr # make cc -o cdr_odbc.so cdr_odbc.o -lodbc

Hello, I just upgraded from Xen-3.3.1 to Xen-4.0.0. System is Gentoo, Hardware is DualCore AMD Athlon, 8GB RAM. The kernel was upgraded from OpenSUSE 2.6.27.29-0.1.1 to Gentoo-2.6.32-xen- r1. The first boot failed with an OOM error during kernel/initrd load, so I adjusted the dom0_mem option and had to increase it''s avalue from 256M to at least 400M until the dom0 could boot. At all

Hi all, sorry for the long posting. Samba 2.2.x is outdated. Trying to switch to 3.0.7 with no success. The vfs layer is one of my current problems.

Hey I wanted to try my hand at doing some GPU passthrough so on my ASUS M5A97 which in the pass worked with an older BIOS (but said BIOS had issues after S3 suspend) - but with a BIOS the PCI passthrough does not work. That is due to:: (XEN) IVHD Error: Invalid IO-APIC 0xff (XEN) AMD-Vi: Error initialization

Today is my day! This is with Xen 4.4 (pulled today) when I build a kernel in dom0 and have two guests launching at the same time. This is what I get: (XEN) Assertion ''l1e_get_pfn(MAPCACHE_L1ENT(hashent->idx)) == hashent->mfn'' failed at domain_page.c:203 and it blows up.
