Hello, When I try to mount a cleany unmounted XFS filesystem, I get those errors in the log : [1650856.121229] XFS (dm-24): Mounting V4 Filesystem [1650856.135455] XFS (dm-24): Log inconsistent or not a log (last==0, first!=1) [1650856.135461] XFS (dm-24): empty log check failed [1650856.135463] XFS (dm-24): log mount/recovery failed: error 22 [1650856.135495] XFS (dm-24): log mount failed I have tried xfs_repair but… manitou:~ # xfs_repair /dev/dm-24 Phase 1 - find and verify superblock... couldn't verify primary superblock - not enough secondary superblocks with matching geometry !!! attempting to find secondary superblock... ........................................ After a lot of dots, xfs_repair can’t find secondary superblocks. This is where my knowledge of XFS filesystem stops. Looking at the superblock information, I have a feeling that the primary superblock is fine but not the secondary superblocks (strange blocksize and dblocks numbers).
Is there any way to copy the primary superblock to the secondary superblocks? Maybe this is not a good idea? Thank you for any help! manitou:~ # xfs_db /dev/dm-24 xfs_db> sb 0 xfs_db> p magicnum = 0x58465342 blocksize = 4096 dblocks = 805306368 rblocks = 0 rextents = 0 uuid = 1da22ae2-a572-4db7-b177-b90021a20863 logstart = 536870916 rootino = 128 rbmino = 129 rsumino = 130 rextsize = 1 agblocks = 201326592 agcount = 4 rbmblocks = 0 logblocks = 393216 versionnum = 0xb4a4 sectsize = 512 inodesize = 256 inopblock = 16 fname = "\000\000\000\000\000\000\000\000\000\000\000\000" blocklog = 12 sectlog = 9 inodelog = 8 inopblog = 4 agblklog = 28 rextslog = 0 inprogress = 0 imax_pct = 5 icount = 15424 ifree = 147 fdblocks = 269387727 frextents = 0 uquotino = 0 gquotino = null qflags = 0 flags = 0 shared_vn = 0 inoalignmt = 2 unit = 0 width = 0 dirblklog = 0 logsectlog = 0 logsectsize = 0 logsunit = 1 features2 = 0x8a bad_features2 = 0x8a features_compat = 0 features_ro_compat = 0 features_incompat = 0 features_log_incompat = 0 crc = 0 (unchecked) pquotino = 0 lsn = 0 xfs_db> sb 1 xfs_db> p magicnum = 0xf6b89fbf blocksize = 1483932129 dblocks = 15694009933101722137 rblocks = 11068626756016902811 rextents = 1593063622148300128 uuid = 6d1ec280-7f96-c817-0f72-d68433061de8 logstart = 17414611744493230066 rootino = 9197560587205818314 rbmino = 1554642860151675405 rsumino = 377387355824336886 rextsize = 1433889823 agblocks = 3940333176 agcount = 2930968516 rbmblocks = 422920841 logblocks = 4017127169 versionnum = 0xd520 sectsize = 19409 inodesize = 16393 inopblock = 2470 fname = "\323R|\0066\274\271\252\240\370-\231" blocklog = 164 sectlog = 42 inodelog = 53 inopblog = 10 agblklog = 72 rextslog = 24 inprogress = 224 imax_pct = 46 icount = 11911544493988237103 ifree = 3385761089021187134 fdblocks = 9395999607433847230 frextents = 7946546560364525221 uquotino = 15084273978162174417 gquotino = 478665847475212977 qflags = 0x1301 flags = 0x37 shared_vn = 3 inoalignmt = 3222551805 unit = 3368784749 width = 3167603851 dirblklog = 130 logsectlog = 143 logsectsize = 2101 logsunit = 2030308911 features2 = 0x5d5cbbfe bad_features2 = 0x2afcd122 features_compat = 0x2a3d35d5 features_ro_compat = 0xa4e58ba9 features_incompat = 0x13dccb60 features_log_incompat = 0xe79d437a crc = 0xbd38d745 (unchecked) pquotino = 7778233919291903441 lsn = 0xa8ffb559acd96aea xfs_db> sb 2 xfs_db> p magicnum = 0x41474341 blocksize = 1195590471 dblocks = 4847921951085253716 rblocks = 4846789398308864835 rextents = 4702132125296707412 uuid = 41544354-5441-4141-4754-544743544743 logstart = 4703821056660554049 rootino = 4703802364996815473 rbmino = 7814906735281653061 rsumino = 4991471925827290437 rextsize = 1162167621 agblocks = 1162167621 agcount = 1162167621 rbmblocks = 1162167621 logblocks = 1162167621 versionnum = 0x4545 sectsize = 17733 inodesize = 17733 inopblock = 17733 fname = "EEEEEEEEEEEE" blocklog = 69 sectlog = 69 inodelog = 69 inopblog = 69 agblklog = 69 rextslog = 69 inprogress = 69 imax_pct = 69 icount = 4991471925827290437 ifree = 4991471925827290437 fdblocks = 4991471925827290437 frextents = 4991471925827290437 uquotino = 4991471925827290437 gquotino = 4991471925827290437 qflags = 0x4545 flags = 0x45 shared_vn = 69 inoalignmt = 1162167621 unit = 1162167621 width = 1162167621 dirblklog = 69 logsectlog = 69 logsectsize = 17733 logsunit = 1162167621 features2 = 0x45454545 bad_features2 = 0x45454545 features_compat = 0x45454545 features_ro_compat = 0x45454545 features_incompat = 0x450a6461 features_log_incompat = 0x74612e75 crc = 0x6e697469 (unchecked) pquotino = 8531350831795363699 lsn = 0x74617420302e3032 xfs_db> --- Stéphane Larose Analyste de l'informatique Institut de Biologie Intégrative et des Systèmes (IBIS) Pavillon Charles-Eugène-Marchand Université Laval |
