Hello list
A disk, part of a raid failed and I have to replace it.
My problem is the swap partition which is in raid0. The rest partitions
are in raid1 and I successfully removed them.
The partition in swap cant removed because is probably active.
How can I stop swap and remove partition?
After replacing the faulty disk and rebuilt how I start swap again?

Thank you in advance
Nikos
