SubjectRe: massive filesystem corruption with 2.4.9
Date
i had similar problems with 2.4.6. unfortunately i didn't save the errors so
i can't compare the msg's. i just can say that with 2.4.6 it destroyed the
ext2 on a 40GB and 60GB maxtor disk. since then my nfs server is running
2.2.19 with works fine (with minor promblems*).

* after a client mounted an exprots once. i cant unmount that partition on
the server after the client unmounted the exports.
