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
