17、r可以使用exportfs -i o命令臨時(shí)輸出資源/vol/vol0/pubs -rw=host1:host2,root=host1/vol/vol1 -rw=host2/vol/vol0/home添加輸出到/etc/exportsSpecifies the full path to the directory that is exportedAll hosts can mount the /vol/vol0/home directory as read-write if an option is not specifiedThis option gives read-write permi

18、ssions to host2 only. All other hosts have no accessThis option gives host1s root user has root accessThe first option is listed following a dash. Additional options are separated by commas. In this example the -rw option allows host1 and host2 to mount the pubs directory. Host names are listed sepa

19、rated by colons在添加Exports到/etc/exports后, 使用exportfs -a 命令重新去加載/etc/exports文件system rdfile /etc/exports#Auto-generated by setup Mon Apr 30 08:32:21 GMT 2007/vol/flexvol/qtree -sec=sys,rw=2/vol/vol0/home -sec=sys,rw,root=2,nosuidsystem exportfssystem exportfs -asystem exportfs/vol/flexvol/qtree -sec=s

20、ys,rw=2/vol/vol0/home -sec=sys,rw,root=2,nosuidExportfs命令臨時(shí)輸出使用exportfs 命令去創(chuàng)建一個(gè)臨時(shí)輸出:system exportfs -i -oExample:system exportfs -i -o ro=host1 /vol/vol0/home NOTE: 當(dāng)存儲(chǔ)重啟后，該配置會(huì)消失Exportfs參數(shù)顯示所有正在輸出的內(nèi)容:system exportfs添加輸出到/etc/exports 文件:system exportfs -p options path重新加載/etc/exports 文件:system export

22、從一個(gè)客戶端mount:通過(guò)Telnet或者其他手段登陸到一臺(tái)主機(jī)上創(chuàng)建一個(gè)目錄作為mount點(diǎn)Mount存儲(chǔ)到mount點(diǎn)上登陸mount點(diǎn)執(zhí)行l(wèi)s l確認(rèn)mount已經(jīng)生效telnet 0 (1)#mkdir /system-vol1-qt1 (2)mount system:/vol/vol1/qtree1 /system-vol1-qt1 (3)cd /system-vol1-qt1 (4)#ls l (5)-rwxr-xr-x root 719634 FEB 11 2004 ,general-rwxr-xr-x root 719634 FEB 13 2004 ,policy系統(tǒng)的監(jiān)控目
