:I have one question regarding the usage of NFS cookies. I read the
:following passage in the mailing list archive:
:
:--------
:
:The BSD code simpy re-reads all of the directory blocks until it
:hits the right offset again whenever it gets NFSERR_BAD_COOKIE. However,
:suppose you have a directory of 3 blocks. You read the first block.
:Your offset is now at the end of the first block. You delete all the
:files in the first block. You want to read the 2nd block. You get
:BAD_COOKIE. So then you start again from the beginning, until you
:are at the wanted offset. However, the first block has disappeared now,
:so your offset lands you at what was originally the 3rd block. You've
:missed the 2nd block entirely.
:
:-------
:
:Is this problem solved or not in FreeBSD 4.0-Release?
:
:-Zhihui
I think this problem has been solved, at least insofar as Solaris
clients (which are sensitive to BAD_COOKIE returns from a FreeBSD
NFS server) are concerned .
