After adding new drive to system 2 of old drives was installed on one cable, and (by fatal flaw) both as slave. And after FBSD is booted it writed identical information onto both of that drivers simultaneously. As a result both filesystems is down. After that fsck was runed... and now very important data is lost. is was from words of the system administrator. Is it possible to recover data? I understand what I give you very small information, but it is all of I know. there is an example: newserver# ls /backup/ Distr Profiles all buh home pto smeta newserver# ls -i /backup/ ls: all: Bad file descriptor ls: buh: Bad file descriptor ls: smeta: Bad file descriptor 6007573 Distr 14348288 Profiles 7936 home 12054848 pto It is obvious, that the part of inodes was lost. How can we restore it? May be, it is possible to recover that by info what is in the files? Thank you in advance, and sorry for a bad English. Vl.

I leave the inode magic to someone else, but for your filedata; I'd start with making a binary file copy of the whole drive (dd using raw device) so that you can dig trough it, maybe even copy the data parts that you need from it. If you have a spare drive that is exactly the same type you could make a binary copy of the disk to it, and don't need to worry about making the prolem worse while recovering the data with inode magic. Hope this helps you a bit.

It is however checked in case I try to delete the file: bash-2.04# rm /tmp_mfs/test # get rid of the overriding file bash-2.04# rm /tmp_mfs/test # get rid of the underlying file override rw-r--r-- root/wheel schg for /tmp_mfs/test? y rm: /tmp_mfs/test: Operation not permitted Now, this to me seems like a bug, but it could very well be due to my lack of understanding of how union mounted filesystems work. If the file exists in the underlying FS, shouldn't the permissions and flags be honored before a 'create' is attempted in the 'upper' FS ? This clearly does not look like it is the case currently.
