I'm having I/O errors on my clients who are mounting 3.1.1 via gluster native NFS. The clients are running NGINX. Any advice appreciated! Perhaps my access mode is incorrect for nfs? The throughput is about 20Mbps sustained, but the system benched at about 600-900Mbps so that shouldn't be a problem. Errors along the lines of: 2010/12/22 08:09:32 [alert] 12206#0: *5807333 sendfile() failed (5: Input/output error) while sending which matches to: nfs.log: [2010-12-22 16:07:36.937671] I [dht-common.c:369:dht_revalidate_cbk] pool-dht: subvolume pool-client-1 returned -1 (Invalid argument) (one system is gmt, the other pst) - NFS in fstab on clients: 10.2.16.51:/pool /gfs1 nfs rw,bg,rsize=8192,wsize=8192,timeo=14,noatime,intr,soft,retrans=6 0 0 - GFS configuration: 2 nodes running ubuntu 10.04.1LTS 1 brick per node consisting of EXT4+LVM on two RAID1 2TB drives (total of 2TB per node) - GFS create line: gluster volume create pool transport tcp 10.2.16.51:/pool/raw 10.2.16.52:/pool/raw - Access mode: client 1 accesses nfs on node 1 client 2 accesses nfs on node 2 - Interfaces 3 gige nics on each node bonded in bond mode 6 Cheers Kon
