UFS fsck -y failed
If fsck -y UFS failed
# fsck -y ... UNKNOWN FILE TYPE I=8408063 UNEXPECTED SOFT UPDATE INCONSISTENCY CLEAR? yes fsck_4.2bsd: bad inode number 8408064 to nextinode
Try to mount UFS read-only
# mount -r /dev/daXs1d /mnt # find /mnt -type f -and -size -1G -print > /root/T2 # tar -T /root/T2 -cf - | ssh admin@bak "cat > host-home.tar"
If ls can not see any files or directories, you may try
- /usr/ports/sysutils/ffs2recov
- /usr/ports/sysutils/scan_ffs
- /usr/ports/sysutils/sleuthkit
- /usr/ports/sysutils/autopsy
Using autopsy
# autopsy localhost using browser to connect http://localhost add case -> add host -> add image -> ...
Bad Partition Table
Using magicrescue
/usr/ports/sysutils/magicrescue
magicrescue can rescue following file types (ls /usr/local/share/magicrescue/recipes/)
- avi
- flac
- gzip
- mp3-id3v1
- perl
- canon-cr2
- gimp-xcf
- jpeg-exif
- mp3-id3v2
- png
- elf
- gpl
- jpeg-jfif
- msoffice
- zip
e.g. 將欲搶救的硬碟拆下，用 USB-to-ATA/SATA 轉接器 magicrescue -r msoffice -r jpeg-jfif -r jpeg-exif -d ~/output /dev/da0 或 (避免多次讀取 /dev/da0) dd if=/dev/da0 of=/big/da0img magicrescue -r msoffice -r jpeg-jfif -r jpeg-exif -d ~/output /big/da0img
