I have looked to old emails and every xfs_repair fixes problem and next time different block/inode pops out. I'm trying to lookup files using inode numbers from old emails. If i remember correctly, files/dirs are usually created in some website cache directory. (ie. generated from template by php and saved to disk for later use). So my lookup will probably come to nothing. Last reported force shutdown was on cache file. > > > (kernel 4.8.15) > > Mar 14 02:36:29 vps2 kernel: [54799.061956] XFS (dm-2): Metadata corruption detected at xfs_attr3_leaf_read_verify+0x5a/0x100 [xfs], xfs_attr3_leaf block 0x24e70268 > > Unfortunately the read path is a bit less interesting.
