Yes. ftp is just more mature. For instance it supports directory listings, which means that the client can show directories on the other side.Is there a benifit of using ftp instead of tftp
A command to start an ftp server on the Lacie could be:
- Code: Select all
tcpsvd -vE 0.0.0.0 21 ftpd -v /mp2
Some random thoughts:
Ext3:
You can read that ext3 disk on a Windows machine, using tools like explore2fs. However, I think the disk has to be cleanly unmounted for that.
Data corruption:
As you had 3 damaged partition tables (at the beginning of the disks) and 2 corrupted raid headers (at the end of the disks), I can hardly imagine there is no corruption in between. (Yet is it possible. I just can't think what actually happened to your system)
Because the data is stored redundant, a corruption on a certain place can be covered by re-calcultating the value from the parity. Unfortunately raid5 contains redundancy, but no error correction. When a parity doesn't fit on it's 4 data chunks, there is no way to tell *which* block is corrupted. Only data analysis can tell. (The one possibility out of 5 which gives a nice photograph is the right one.)
So how can this help? When you have certain corrupted file, you can try to assemble a degraded array in 5 different ways (omitting each disk once) to see if you can extract the good file.
Unfortunately I know no easy way to automate this. Unless there is some pattern in the corruption I don't think it's possible either.
Yes, you have to unmount and remount it:Do I have to somehow reset or reinitialize the USB drive again to get it stop making those errors?
- Code: Select all
umount /mountpoint
mount /dev/sef1 /mountpoint
