I am migrating my NFS file server from RHEL3 to RHEL5 and moving up to NFS v4 where i can. Once question I still have is what is the maximum rsize and wsize i can set for V4 automount? The file include/linux/nfsd/const.h says teh maximum is 32*1024 (32K) but some google postings claim that does not apply to V4; I've tried v4 automounts with values up to 1048576 and none of the machine have complained. A part of the new server's duties will be to accept the RMAN (oracle) backups so speed is important. I am using a dedicated gigabit switch with jumbo frames (9000 bytes) and I have tuned the TCP for the "private" interfaces on all the connected interfaces. These is the only parameter I am not sure what I can get away with. I have it set to 32768 for the current v3 setup. -- Stephen Carville -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
