how to find out total capacity and raid level of btrfs file system
I know df does not report the correct size for btrfs raid systems. Is there any other way to find out the total capacity of a btrfs file system? Or at least the raid level for data / metadata? My test system is Ubuntu 10.10 alpha with btrfs 0.19 and a 2.6.35 kernel (don''t know which rc). # uname -a Linux ubuntu 2.6.35-12-generic #17-Ubuntu SMP Mon Jul 26 18:48:06 UTC 2010 x86_64

PROBLEM: I/O stalls when running fstress against multi-device fs
Chris: I can consistently reproduce I/O stalls when running fstress (as found in Autotest) against a six volume btrfs filesystem mounted without options. The volumes are independent disks from RAID controllers, and the test systems are eight core Intel and AMD machines running current btrfs-unstable. The stalls occur at variable times into the runs. The affected system ceases to do I/O

Recovering data from old corrupted file system
I have a corrupted multi-device file system that got corrupted ages ago (as I recall, one of the drives stopped responding, causing btrfs to panic). I am hoping to recover some of the data. For what it''s worth, here is the dmesg output from trying to mount the file system on a 3.0 kernel: device label Media devid 6 transid 816153 /dev/sdq device label Media devid 7 transid 816153

[BUG, PATCH] xen-4.1-3 xend/XendDomainInfo.py#device_configure() TypeError
Hello, I noticed a bug in Xen-4.1-3, which is also still present in xen+git. I know that the Python xend is deprecated, but I''m stuck with xen-4.1 until xen is usable with libvirt, so my patch might still be helpful for others. This is a follow-up to <http://lists.xen.org/archives/html/xen-users/2012-11/msg00069.html>, which still keeps me busy. /xen/xend/server/SrvDomain.py

Building from a source-code library under windows
Dear All, I have a pair of .cpp and .def file can be compiled using VC++ and works perfectly well in S-PLUS. I wanted to do the same for R; so I followed the guidline given in "Building from a source-code library under Windows" as much as possible and manage to compile them using VC++ and call it from R. But it gives different answer from the one called from S-Plus. I know that I did

Resize command syntax wrong?
Currently the resize command is under filesystem, and takes a path to the mounted filesystem. This seems wrong to me. Shouldn''t it be under device, and take a path to a device to resize? Otherwise, how can a resize operation when you have multiple devices make any sense? -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to

Can't replace a faulty disk of raid1
Hello, I had a raid1 btrfs (540GB) on vanilla 3.6.3, a disk failed, and removed it at power off, plugged in a new one, partitioned it (to 110GB, by error), and added it to btrfs. I tried to remove the missing device, and it said "Input/output error" after a while. Next attempts simply gave "Invalid argument". I repartitioned, rebooted the system, and made the partition grow:

[PATCH v5 virtio 01/11] virtio: allow caller to override device id in vp_modern
To add a bit of vendor flexibility with various virtio based devices, allow the caller to check for a different device id. This adds a function pointer field to struct virtio_pci_modern_device to specify an override device id check. If defined by the driver, this function will be called to check that the PCI device is the vendor's expected device, and will return the found device id to be
