Dear linux-raid mailing list,
I have a RAID0 array of four 3TB disks that failed on the "third" disk.
I am aware of the non-redundancy of RAID0 but I would like to recover the
filenames from that RAID0. If I could recover some data it would be a bonus.
Below you'll find the outputs of the following commands
mdadm --examine /dev/sd[abcd]1
fdisk -l
where sda1, sdb1, sdc1 and sdd1 should be the 4 RAID devices.
What could be my next step?
I thank you for your time
Michel Dubois

Michael,
I'll preface my reply with the statement that I am far from an expert at
this but I can read and understand the descriptions of the different RAID
levels and it seems to me with a RAID0 you are SOL if you lose a device in
the array. Just by the very nature of the RAID0 configuration there is
absolutely NO redundancy. The only reason anyone would configure such a
system is for SPEED and the only data that should be permitted on a RAID0
array is temp or working data that is recoverable by other means in the
event of a failure. I know of many Videographers that use a SSD RAID0 array
for working on their current project but they also copy that array out
about every hour for backup.
I pose only one question to you. Did you have a backup?
Good luck.

Hi
Which file system did you use?
I once wrote some code to get files out of an ext3 filesystem,
http://www.open-std.org/keld/readme-salvage.html
Maybe you can make some corrections for it to work
as I remember the code, then if you hit a directory, it will salvage the file names and the files
of that directory.
Best regards
keld
