今天在转码业务平台挂载中兴分布式存储时，出现了挂载失败： linux-82ke:~ # mount -t nfs 192.168.202.60:/mnt/zxdfs/CM_South23/root/cccloud_tenant_id10001155 /mnt/D989/60/mnt/wfs10 -v mount.nfs: timeout set for Wed Jul 30 15:39:52 2014 mount.nfs: trying text-based options 'vers=4,addr=192.168.202.60,clientaddr=192.168.199.4' mount.nfs: mount(2): No such file or directory mount.nfs: trying text-based options 'addr=192.168.202.60' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 192.168.202.60 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=17 mount.nfs: trying 192.168.202.60 prog 100005 vers 3 prot UDP port 39325 mount.nfs: mount(2): Connection timed out mount.nfs: trying text-based options 'vers=4,addr=192.168.202.60,clientaddr=192.168.199.4' mount.nfs: mount(2): No such file or directory mount.nfs: trying text-based options 'addr=192.168.202.60' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 192.168.202.60 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=17 mount.nfs: trying 192.168.202.60 prog 100005 vers 3 prot UDP port 32954 mount.nfs: mount(2): Connection timed out mount.nfs: trying text-based options 'vers=4,addr=192.168.202.60,clientaddr=192.168.199.4' mount.nfs: mount(2): No such file or directory mount.nfs: trying text-based options 'addr=192.168.202.60' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 192.168.202.60 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=17 mount.nfs: trying 192.168.202.60 prog 100005 vers 3 prot UDP port 37809 mount.nfs: mount(2): Connection timed out mount.nfs: Connection timed out 中兴分布式存储那边的/etc/exports配置为： /data 192.168.199.*(rw,no_root_squash,sync,no_subtree_check) 但是奇怪的是，如果将/etc/exports修改为： /data/test 192.168.199.4(rw,no_root_squash,sync,no_subtree_check) 挂载又是成功的。 最后无意间使用了如下配置后，居然正常了： /data 192.168.199.0/24(rw,no_root_squash,sync,no_subtree_check) (责任编辑：IT) |
