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

From: Anand <anand.jain@oracle.com> This patch adds creation-time to the snapshot list display, which would help user to better manage the snapshots when number of snapshots grow substantially. This patch is developed and on top of the send/receive btrfs and btrfs-progs repo at git://github.com/ablock84/linux-btrfs.git (send-v2) git://github.com/ablock84/btrfs-progs.git (send-v2)

Changes v1-v2: - Remove restriction that BTRFS_IOC_GET_DEVICE_STATS is a privileged operation - Cast u64 to unsigned long long for printf() Changes v2-v3: - Rebased on Chris'' current master Changes v3-v4: - Add padding at end of ioctl structure Changes v4-v5: - The statistic members in the ioctl are now organized as an array of 64 bit values. Symbolic names for the array indexes

The kernel patch series just sent (Subject: "Btrfs: scrub: print path to corrupted files and trigger nodatasum fixup") introduces two new ioctls to do in-kernel filesystem path construction. This series provides the corresponding userspace changes, adding two new commands to the btrfs utility: -- btrfs resolve inode [-v] <inode> <path> resolves an <inode> to all

v1 was here: https://www.redhat.com/archives/libguestfs/2018-October/msg00047.html v2 was here: https://www.redhat.com/archives/libguestfs/2018-October/msg00051.html v3: - Back to using string/string_format and attribute/attribute_format. - Add both single_element and single_element_format. - Rebased and retested. Rich.

Consolidate and extend the use of funky start_element() etc macros. Rich.

v1 was here: https://www.redhat.com/archives/libguestfs/2018-October/msg00047.html However it was broken in a few ways. First of all the documentation was broken because "/**" enhanced comments were not permitted on macros. This is fixed in the new 1/4 patch. Secondly we didn't use single_element() everywhere possible, which is fixed in the new 4/4 patch. Lastly I've

Hi, as it was already discussed on this list, here it is my attempt in splitting virt-p2v in an own repository. Sadly there are things that must be copied from libguestfs, as it cannot be avoided. The approach taken was to run a script (will send separately) to just get the "p2v" subdirectory with its history as own repository, and then add in few followup commits all the bits needed
