hi all- i had a wonderful crash ( my fault, don't mess with hardware while the box is still running, no matter how steady your hands :| ). anyhoo, my 3ware RAID 5 volume is a bit unhappy now. when running fsck, i get the following: ---- # fsck -y /dev/da0s1d ** /dev/da0s1d CANNOT READ BLK: 1464762144 CONTINUE? yes THE FOLLOWING DISK SECTORS COULD NOT BE READ: 1464762144, 1464762145, 1464762146, 1464762147, LOOK FOR ALTERNATE SUPERBLOCKS? yes 32 is not a file system superblock CANNOT READ BLK: 458687976 CONTINUE? yes THE FOLLOWING DISK SECTORS COULD NOT BE READ: 458687976, 458687977, 458687978, 458687979, 458687980, 458687981, 458687982, 458687983, 458687984, 458687985, 458687986, 458687987, 458687988, 458687989, 458687990, 458687991, CANNOT READ BLK: 917375920 CONTINUE? yes THE FOLLOWING DISK SECTORS COULD NOT BE READ: 917375920, 917375921, 917375922, 917375923, 917375924, 917375925, 917375926, 917375927, 917375928, 917375929, 917375930, 917375931, 917375932, 917375933, 917375934, 917375935, CANNOT READ BLK: 1376063864 CONTINUE? yes THE FOLLOWING DISK SECTORS COULD NOT BE READ: 1376063864, 1376063865, 1376063866, 1376063867, 1376063868, 1376063869, 1376063870, 1376063871, 1376063872, 1376063873, 1376063874, 1376063875, 1376063876, 1376063877, 1376063878, 1376063879, SEARCH FOR ALTERNATE SUPER-BLOCK FAILED. YOU MUST USE THE -b OPTION TO FSCK TO SPECIFY THE LOCATION OF AN ALTERNATE SUPER-BLOCK TO SUPPLY NEEDED INFORMATION; SEE fsck(8). ---- this is all well and good, but according to 'man 8 fsck', there is no '-b' option. any thoughts on way around this? I'm running on 5.4-STABLE. thanks in advance, darren david
