Hi Mohan: Here is my understanding of the partition layout on your current system on the basis of your mail. (hd0,0) winxp winxp ntfs 8Gb (hd0,1) boot /boot ? ? (hd0,2) root / ext3 12Gb (hd0,3) extended (hd0,4) swap none swap ? (hd0,5) home /home NFS j 12Gb (hd0,6) rest ? FAT32 ? Could you please confirm if indeed the above layout matches with what you got ? Here are few queries: . What error did you get when you tried to specify swap of 4Gb size ? Here is a practical suggestion, swap size can be in a range min : RAM size + 256Mb max : 2 x RAM size swap space is usable to the extent that is mappable by the kernel. Most 64-bit systems are actually using 48-bit addressed systems. Additionally swap is slow memory and so large chunks of it actually lead to thrashing the system rather than being useful. It is difficult to appreciate the point if one is planning to run a single OS as in most cases, the swap is really not much used. If one were to run a Virtual machine and host a kernel, then suddenly a lot of swap space would get utilized. Perhaps even large heap allocations (malloc'd 2GB+ memory) may show up some patterns here. I suggest, that you use a 1:1 RAM to swap ratio and throw in a bit like 258 Mb RAM. . Why would you like to use NFS with journalling for /home ? If i understand correctly, NFS is Networked File System which is useful for systems which mount partitions over network. Look forward to your replies. thanks Saifi.
