Hi All,

I've had a sector failure on one of the source disks during a raid 5 rebuild.

According to the log it tries to do a puncture (rebuild with errors) but the target disk starts throwing sense keys & it all fails.
I had not read the log file, so when it failed the first time, so I just shoved in another disk, the log showed the same errors, source then target errors stopping even the punctured rebuild.
I would be surprised but not shocked by two DOA's:-)

The question finally:- is the omconfig remove dead segments of any use here, on the source disk?

i.e. can I remove the dead segments suffer the file loss but rebuild the raid 5.
