assigned to johnsonm Is this still an issue or has it been fixed? Hi, it's still an issue. Cheers -- Mario Bob, you know more about NFS than I do, I think. This is fixed in (at least) the 2.4.2 kernel. Sorry, don't know of any patches for 2.2 and earlier kernels. as we have just purchased received and installed the latest and greatest alpha product box (which tells kernel 2.2.16), please point me to all specific packages and places required to be downloaded and installed to fix this error. thanks, support This is fixed in the current Alpha Rawhide release. |
Ideally a solution for RH 5.2 (with a 2.0.X kernel) is sought as well... I've tried this on RH 5.2 systems with kernel 2.0.35 and 2.2.9 (with nfsd patch from knfsd 1.3). As well as on stock RH 6.0, or with kernel 2.2.9 (nfsd patch from knfsd 1.3) and 2.2.10-ac1. Using knfsd 1.3 and 1.4. It appears that the utime() function is not implemented properly over nfs. If I do not own a file on an nfs mounted partition, but I do have write access to it utime ("nfs/filename", NULL); does not work. It does work if not on an nfs mounted partition. Here is an example on the nfs mounted partition: [stewart@soleil stewart]$ whoami stewart [stewart@soleil stewart]$ groups eng users mirrors doc [stewart@soleil stewart]$ df .
