dja Posted February 23 Share Posted February 23 (edited) Ran into this after last update. (I think?) Any way to salvage cache data? Diags attached, thanks in advance! *Additional info- I had a encrypted BTRFS RAID0 setup for cache. (2 NVME disks) I attached a older backup with everything as it was before...(2023 file) I ran a BTRFS check on the cache (RO) and got this- parent transid verify failed on 7971232710656 wanted 1126103 found 1124055 parent transid verify failed on 7971232710656 wanted 1126103 found 1124055 parent transid verify failed on 7971232710656 wanted 1126103 found 1124055 Ignoring transid failure [1/7] checking root items parent transid verify failed on 6670712832 wanted 576460752304546710 found 1123222 parent transid verify failed on 6670712832 wanted 576460752304546710 found 1123222 parent transid verify failed on 6670712832 wanted 576460752304546710 found 1123222 Ignoring transid failure parent transid verify failed on 7971232710656 wanted 1126103 found 1124055 Ignoring transid failure [2/7] checking extents parent transid verify failed on 6670712832 wanted 576460752304546710 found 1123222 Ignoring transid failure parent transid verify failed on 7971232710656 wanted 1126103 found 1124055 Ignoring transid failure ref mismatch on [1553951424512 16384] extent item 65535, found 1 tree extent[1553951440896, 16384] root 7 has no backref item in extent tree tree extent[1553951440896, 16384] root 9836619805773266951 has no tree block found incorrect global backref count on 1553951440896 found 2 wanted 1 backpointer mismatch on [1553951440896 16384] ERROR: errors found in extent allocation tree or chunk allocation [3/7] checking free space tree parent transid verify failed on 6670712832 wanted 576460752304546710 found 1123222 Ignoring transid failure parent transid verify failed on 7971232710656 wanted 1126103 found 1124055 Ignoring transid failure [4/7] checking fs roots [5/7] checking only csums items (without verifying data) parent transid verify failed on 6670712832 wanted 576460752304546710 found 1123222 Ignoring transid failure parent transid verify failed on 6670712832 wanted 576460752304546710 found 1123222 Ignoring transid failure parent transid verify failed on 6670712832 wanted 576460752304546710 found 1123222 Ignoring transid failure parent transid verify failed on 6670712832 wanted 576460752304546710 found 1123222 Ignoring transid failure parent transid verify failed on 6670712832 wanted 576460752304546710 found 1123222 Ignoring transid failure parent transid verify failed on 6670712832 wanted 576460752304546710 found 1123222 Ignoring transid failure parent transid verify failed on 7971232710656 wanted 1126103 found 1124055 Ignoring transid failure parent transid verify failed on 7971232710656 wanted 1126103 found 1124055 Ignoring transid failure parent transid verify failed on 7971232710656 wanted 1126103 found 1124055 Ignoring transid failure parent transid verify failed on 7971232710656 wanted 1126103 found 1124055 Ignoring transid failure parent transid verify failed on 7971232710656 wanted 1126103 found 1124055 Ignoring transid failure parent transid verify failed on 7971232710656 wanted 1126103 found 1124055 Ignoring transid failure parent transid verify failed on 7971232710656 wanted 1126103 found 1124055 Ignoring transid failure [6/7] checking root refs [7/7] checking quota groups skipped (not enabled on this FS) ERROR: transid errors in file system Opening filesystem to check...

I had removed, started, stopped and re-added them but forgot to put them in correctly, that being encrypting BTFRS RAID0. I did the same thing again but with the correct options and after running a repair from command line it restored things. I'm not seeing any loss of data (at the moment...) So I guess it worked? I only had dockers/VMs on that and have multiple backups, so I guess I can restore if need be. (and freeze my backup tools for a bit!! lol) Thanks for the help. Quote Link to comment
