Hi All, I''ve been using btrfs on and off for a few years now. It gets great performance in my dev environment when dealing with big files, which I appreciate. This week my home machine started complaining about a disk error on my btrfs partition. Dropping to the maintenance console and running btrfsck gives the following, and btrfsck aborts without attempting a fix. Can anyone offer some advice? warning, start mismatch 1144184832 1143091200 block 1144184832 rec extent_item_refs 1, passed 1 warning, start mismatch 1144418304 1144430592 The volume actually mounts and seems to run OK, but I would like to resolve the error. It would not be a huge burden to backup the volume and reformat, but I figure that I can contribute to stabilization of btrfs by going through this exercise. Thanks! Any further details required will be supplied. My setup is as follows: Ubuntu 12.04 LTS AMD Phenom(tm) II X6 1090T Processor MemTotal: 16176556 kB Mainboard: ASUS M4A88T-M onboard everything else -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
