ddrescue to the rescue!
Get a another new disk, then ddrescue the one with the read error to
the new disk.
Assemble the array using the new disk instead of the one with the read error.
You will loose the blocks that can't be read of course.
And in the future do run raid check/scrubbing at regular intervals. ;)

Zitat von Chris Purves <chris@xxxxxxxxxxxx>:
Hello,
I have a 5 disk RAID 5 where one of the disks died completely. I
replaced the failed disk and added a new disk to the array. While
it was rebuilding the new disk there was a read error on one of the
"good" disks that caused the disk to be reset by the controller and
the array was brought down.
I can bring the array back up in degraded mode by running mdadm
--assemble --force /dev/md1; however, I have been unable to build
the fifth disk. I would appreciate any help.
