Hallo, Blair,

Du meintest am 23.11.11:

I had tried ... about 4 Tbyte data have gone.

3 disks bundled with data=raid0, metadata=raid1.

One disk had problems, before I run "scrub" I could read most files,  
Running "scrub": all had gone.

One big problem of btrfs seems to be: you can't see on which partition/ 
disk the defect sector (or something else) may be, if there is 1 error  
in 1 partition you have to restore the complete bundle of disks/ 
partitions.

Yes - I know: btrfs is still under construction.

In my special case: the 4 TByte are a kind of video archive. No  
"valuable" data, only "nice to have". And old people still know the  
behaviour of old 35 mm film and/or VHS cassettes: they have errors. But  
these errors don't damage the whole archive.

Viele Gruesse!
Helmut
