hi all i use xfs filesystem over nfs I am using the xfs file system via NFS on two Linux servers. Even though xfs is full, you will not get a 'no space' message through nfs. The server's load average goes up and the kworker consumes the CPU. The server's nfs service is not responding. When ext3 is full in the same environment, I get a 'no space' message. Which part of nfs and xfs should be checked? Below is the environment I am using. kernel : nfs server 3.4.113 vanilla, nfs client 2.6.32-573.el6.x86_64 nfs : nfs v3 with tcp ================================================================== nfs server ================================================================== /dev/mapper/lv2 500G 500G 20K 100% /lv2 /lv2 0.0.0.0/0.0.0.0(rw,async,wdelay,nohide,nocrossmnt,insecure,no_root_squash,no_all_squash,no_subtree_check,insecure_locks,no_acl,fsid=1543743056,anonuid=65534,anongid=65534) ================================================================== nfs client ================================================================== 10.0.0.20:/lv2 500G 500G 32K 100% /mnt/2 nfsstat -m /mnt/2 from 10.0.0.20:/lv2 Flags: rw,relatime,vers=3,rsize=32768,wsize=32768,namlen=255,hard,proto=udp,timeo=11,retrans=3,sec=sys,mountaddr=10.0.0.20,mountvers=3,mountport=2047,mountproto=udp,local_lock=none,addr=10.0.0.20 ================================================================== server top log ================================================================== top - 21:54:10 up 58 min, 0 users, load average: 8.50, 8.37, 8.83 Tasks: 347 total, 2 running, 345 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0%us, 4.2%sy, 0.0%ni, 95.8%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 12368 root 20 0 0 0 0 S 12 0.0 4:32.44 kworker/2:2 11092 root 20 0 0 0 0 S 10 0.0 4:42.57 kworker/3:1 11166 root 20 0 0 0 0 R 9 0.0 2:09.47 kworker/5:1 12473 root 20 0 0 0 0 S 8 0.0 2:09.36 kworker/4:2 2944 root 20 0 0 0 0 D 6 0.0 2:09.10 nfsd 2953 root 20 0 0 0 0 D 6 0.0 2:24.65 nfsd 3024 root 20 0 0 0 0 D 6 0.0 2:23.12 nfsd
