The raidsync wasn't Ok, so you've lost a good chunk of the filesystem then? I don't lik eto say it, but double disk failures tend to result in unrecoverable data loss. Given the contents of this email, I know you don't have backups to restore from, so you might be left with only bits and pieces even if a repair can be made to run successfully. > finished and now i'm fighting 3 weeks or more i don't no any more :-( to > repair the file system. > > I tried a lot of different versions of xfs_repair (2.9.4, 2.9.8, 2.10.2, > 3.0.4, 3.1.2, 3.1.6, 3.1,8), but every precompiled version got an > "segmentation fault" or hung at phase 3 with 100% cpu load for few day.
