Hi Stephen, I use ext3 with kernel 2.4.14. I'm happy to have verified that nfs+ext3 in journal mode doesn't provide atomic write for the user point of view. My program writes sequential records of 64KB in a file through a nfs mount point. The blocks of data are initialized with a serie of integer: 1, 2, 3 ... I kill the nfsd daemons while two instance of the program are writing their 600 records of 64KB in two distinct files. Then using 'od' i look at the result, and i see some blocks of zero inside the file. The size of these zeroed blocks seems to be multiple of h'4000. NB: My clients and servers are colocalised on the same machine. I obtained the same result with nfsv2 and nfsv3 mount option. I also have the same result using ordered and writeback modes. NB: when i have changed the program in order to initialize the pattern for each record i cannot reproduce the problem ( it seems the timing was changed, as more CPU was done before each write request). Regards, eric
