OK. I have been spending all day on this and am trying to understand
(and fix) the different types of pool duplication and corruption.
Types of Duplicate checksums:
1. Same checksum but contents differ -- INTENTIONAL - nothing to fix
2. Same checksum and compressed content
I have found many of these but contrary to my earlier postings
the ones that I examined were not in my error log so they
don't seem to be due to the nfs/link problems (see later)
I don't know what the source of these are though...
3. Same checksums, different compressed content, same zcatted content
As per my earlier email, I found at least one of these
and am not sure why they even exist.
4. Files with *NO* pool entries.
This seems to be what occurs with the
files in my error log that cite the failure of
MakeFileLink
5. HardLinkMax exceeded -- INTENTIONAL - nothing to fix
Hopefully, there are no files with the case of "same content,
different checksums).
In summary:
- 1&5 are by design
- 2&3 are unclear what is causing them
- 4 is clearly do to my filesystem problems
- 2,3,4 could all be "corrected" by a program that crawls through the
cpool and pc chain.
The deeper I probe into this, the more confused I get and the more I
worry about data integrity on my system...
Thanks
