The attachment is my dataset: 1.ccc.shp (the original data) 2.ccc.gwt, which is computed by Geoda; Introduction to the variables in my data: ID: key variable; N_LATITUDE: latitude measured by GPS; E_LONGITUD: longitude measured by GPS; LIVES: attribute data I get the different result of Moran's between ARCGIS and Geoda, R, why?

When I try to umount btrfs filesystem I get always this error with kernel 3.11.4 and 3.11.3, but I can mount and umount without error on kernel 3.11.2.

I'm pulling my hair out trying to setup a mirrored logical volume. lvconvert tells me I don't have enough free space, even though I have hundreds of gigabytes free on both physical volumes. Command: lvconvert -m1 /dev/vg1/iscsi_deeds_data Insufficient suitable allocatable extents for logical volume : 10240 more required Any ideas? Thanks!, Gordon Here's the output from the

Hello On my HP Compaq dc5800 with Ubuntu 13.04 and their 3.8.0-19-lowlatency kernel, I''ve got quite some kernel traces in the syslog. You can find them below or at http://pastebin.com/bLXPBX67 (to avoid line breaks…). These kernel traces all begin with: WARNING: at fs/btrfs/free-space-cache.c:921 __btrfs_write_out_cache+0x6b9/0x9a0 [btrfs]() Most of the time, it starts with: Call

Hi Alasdair, This is dm-ioband v1.12.2 release that is a minor update to fit the current dm-devel tree. Could you please replace dm-add-ioband.patch in your tree with this patch? And I would appreciate it if you would let me know your thoughts about merging dm-ioband to upstream.

Hi Alasdair, This is dm-ioband v1.12.3 release that is a minor update to avoid sparse warnings other than related to the event tracing. (I used sparse-2009-07-29.) This patch can be applied to the current dm-devel tree and 2.6.31-rc4, so could you please replace dm-add-ioband.patch in your tree with this?

Hi list! I recently butchered my filesystem, and I was wondering if anyone knows how to help. Problem: My filesystem is screwed up, and I can''t mount it at all right now. In the logs, the problem begins around 45s. Background: I''m running a 6x4TB RAID5 array using md. I have a few virtual machines using said array, and one of them is a btrfs storage server. I ran into some

Hi all, I''m running btrfs in a 3-disk RAID1 configuration. After a hard power-off, I''m seeing a lot of hung I/O tasks on this volume, apparently due to a corrupt leaf. I first noticed the problem on kernel 3.4.7, and it''s persisted with 3.4.8. Relevant parts of the kernel log follow. [ 85.179621] block group 38684065792 has an wrong amount of free space [

Hi All, This is the dm-ioband version 1.12.0 release. dm-ioband is an I/O bandwidth controller implemented as a device-mapper driver and can control bandwidth on per partition, per user, per process , per virtual machine (such as KVM or Xen) basis. The major change of this release is that a new bandwidth control policy "range-bw" is supported. This policy is developed by Dong-Jae Kang,

Hi Alasdair and all, This is the dm-ioband version 1.10.5 release. This patch can be applied cleanly to current agk's tree. The only change from the previous version is that some blktrace messages are added by Alan D. Brunelle, thanks Alan. Alasdair, Could you please tell me your opinion about merging dm-ioband to upstream? What else do I have to do? Is there any possibility that dm-ioband

If I manually delete the Q35 USB Controllers, I can use managedsave/start, but I start getting tty errors that don't happen before the managedsave/start. Using libvirt 1.2.18 (-1 Arch) and QEMU git-master (2.4.0.r40384.2d69736). Installed using Q35 chipset. I'm running QEMU git, which allows SCSI controller migration, so I can attempt doing this. I started my guest, and waited for 15
