Hi,
we have "check", "repair", "replacement" and other operations on raid
volumes.
I am not a programmer, but I was wondering how much work it would require
to take current code and implement "rewrite", basically re-writing every
block in the md raid level. Since "repair" and "check" doesn't seem to
properly detect a few errors, wouldn't it make sense to try least
existance / easiest implementation route to just re-write all data on the
entire array? If reads fail, re-calculate from parity, if reads work, just
write again.
The goal of this new mode would be to eradicate pending sectors by
re-writing everything on the drive.
If this doesn't seem like a sensible approach, what would be a sensible
approach to avoid having pending sectors keep being "pending" even after
"check" and "repair"?
