Hello i''ve a data partition in my system formated as btrfs, I can mount the partition without problems, but from time to time I''ve some lockings in the disk that force me to reboot the system. Lately I have been having problems when unmounting the disk too I have been running for several weeks the kernel 3.3.1, and my btrfs-tools are version 0.19+20120328-1 (from debian wheezy) This is the output I am getting from btrfsck, and it always ends up aborting the "checking fs roots" part. $ btrfsck /dev/sda1 .................... ref mismatch on [2188599418880 2072576] extent item 1, found 0 Incorrect local backref count on 2188599418880 root 261 owner 26476652 offset 0 found 0 wanted 1 back 0x6b3435e8 backpointer mismatch on [2188599418880 2072576] owner ref check failed [2188599418880 2072576] ref mismatch on [2188877869056 4231168] extent item 1, found 0 Incorrect local backref count on 2188877869056 root 261 owner 26476649 offset 0 found 0 wanted 1 back 0x97bc7798 backpointer mismatch on [2188877869056 4231168] owner ref check failed [2188877869056 4231168] ref mismatch on [2188882100224 3911680] extent item 1, found 0 Incorrect local backref count on 2188882100224 root 261 owner 26476654 offset 0 found 0 wanted 1 back 0x97bc7840 backpointer mismatch on [2188882100224 3911680] owner ref check failed [2188882100224 3911680] ref mismatch on [2188886011904 1798144] extent item 1, found 0 Incorrect local backref count on 2188886011904 root 261 owner 26476657 offset 0 found 0 wanted 1 back 0x97bc78e8 backpointer mismatch on [2188886011904 1798144] owner ref check failed [2188886011904 1798144] ref mismatch on [2188900532224 1875968] extent item 1, found 0 Incorrect local backref count on 2188900532224 root 261 owner 26476659 offset 0 found 0 wanted 1 back 0x97bc7b70 backpointer mismatch on [2188900532224 1875968] owner ref check failed [2188900532224 1875968] ref mismatch on [2188902408192 2080768] extent item 1, found 0 Incorrect local backref count on 2188902408192 root 261 owner 26476664 offset 0 found 0 wanted 1 back 0x97bc7c18 backpointer mismatch on [2188902408192 2080768] owner ref check failed [2188902408192 2080768] Errors found in extent allocation tree checking fs roots Aborted Is there anything I can do to force a check only in this part while getting more debug? -- 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
