Just a small note:
/mirrors/pub/Hebrew
/mirrors/pub/israel (one file)
are not mirrored, and should be copied to somewhere else before purging an
old disk (if thus decided). It is around 90MB, so it shouldn't be any
problem.

Do we have three disks that one of them failed?
Also keep in mind that raid 5 means less usable place for data (that can
be fetched from elsewhere, in such an event). Is it worth the price?
