I am proposing these two patches for 3.2. They allow the backend to process the REQ_FUA request as well. Previous to these patches it only did REQ_FLUSH. There is also a bug-fix for the logic of how barrier/flushes were handled. The patches are based on a branch which also has ''feature-discard'' patches, so they won''t apply nativly on top of 3.1-rc5. Please review and

Dear list, This is the V4 of the trim support for xen-blkfront/blkback, Now we move BLKIF_OP_TRIM to BLKIF_OP_DISCARD, and dropped all "trim" stuffs in the patches, and use "discard" instead. Also we updated the helpers of blkif_x86_{32|64}_request or we will meet problems using a non-native protocol. And this patch has been tested with both SSD and raw file, with SSD we will

Hi, One of our colleagues spotted a problem in xentop. Sometimes the VBD_WSECT value suddenly becomes unreasonably high, and it turned out xentop reads /sys/bus/xen-backend/devices/vbd-(domid)-(devID)/statistics/wr_sect into an unsigned long long. That value is exposed by blkback, and among other stat counters, it''s a signed integer: drivers/block/xen-blkback/common.h struct

I have some Xen systems running Xen-4.1.1, dom0 linux-2.6.38 patched (it''s gentoo''s xen-sources) and domUs running linux-3.0.4 (vanilla sources from kernel.org). Block devices are phy on LVM2 volumes on DRBD-8.3.9 devices. Not immediately after boot, but after some I/O load on the disks I start seeing these in the domUs: blkfront: barrier: empty write xvdb1 op failed blkfront:

Hello ALL! I am running Fedora 16 x86_64. Due to some dubious problems, that i couldn't resolve, with the TeXLive (2007, which is a default), I removed it. That removed R as well, and some other dependent packages. Then, I installed TeXLive 2011 from CTAN. However, when I wanted to install R, from Fedora's repositories, it asks for some TeX dependencies (for example, tex-preview,

Hi all, I have 3 guests (2-RHEL4 and 1 RHEL6) and have some issues regarding networking between them. The 2 RHEL4 system's use default bridge virbr0 and get ip's of range 192.168.122.0/24 (192.168.122.207, 192.168.122.167) I created another bridge (virbr1) with NAT forwarding (no dhcp). The network i choose was 192.168.100.0/24. And the third system (RHEL6) was assigned static ip-addres

Also, I've noticed that ovirt-node needs refreshing... iirc apevec did tag/release of 2.0.1 from

This patch implements persistent grants for the xen-blk{front,back} mechanism. The effect of this change is to reduce the number of unmap operations performed, since they cause a (costly) TLB shootdown. This allows the I/O performance to scale better when a large number of VMs are performing I/O. Previously, the blkfront driver was supplied a bvec[] from the request queue. This was granted to

The goal is to detect when drives start to get an increased error rate, when drives should be replaced soon. Therefore statistic counters are added that count IO errors (read, write and flush). Additionally, the software detected errors like checksum errors and corrupted blocks are counted. An ioctl interface is added to get the device statistic counters. A second ioctl is added to atomically get

Patrick, there following patches fix xenpaging for me. Granttable handling is incomplete. If a page is gone, a GNTST_eagain should be returned to the caller to inidcate the hypercall has to be retried after a while, until the page is available again. Please review.
