List-Post: List-Help: List-Subscribe: , List-Archive: Hello, we ran in trouble while upgrading from 2.4.20pre1 to 2.4.23 kernel on a GNU/Linux box which serves two Solaris 9 clients and one Linux client. When the export get set up and some mount attempt comes, the server starts flooding the logs and screen with: fh_verify: no root_squashed access at session/lastsession (several messages per second). The server doesn't panic or crash --- I am able to shut down knfsd without any harm --- everything works, just the NFS drives are inaccessible. There is a workaround using no_subtree_check as an option in the exports file, but can anyone help me explain this? I found only two relevant posts using Google with "fh_verify root_squashed" as keywords: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=110421 http://www.ussg.iu.edu/hypermail/linux/kernel/0309.1/1159.html Thanks for your time Vaclav Stepan -- Vaclav Stepan w@linux.fjfi.cvut.cz http://linux.fjfi.cvut.cz/~w/ ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
