紧急问题！！！！！

unix-xyz

紧急问题，操作系统启动不成功，报以下错误，我现在知道错误所在了，可是如何修复呀？主要问题是做完系统镜像后，vfstab文件也都改成md的了，后来在调试文件系统时，又将以前备份的vfstab文件改成现在可用的vfstab文件，将改成md文件系统vfstab改名了，现在就启动不了，只能进入单用户模式，且vfstab等文件不能编辑，有什么办法吗？\r\n[root@test]# ls -al vf*\r\n-rw-r--r--   1 root     root        1624 Apr 29 23:13 vfstab\r\n-rw-r--r--   1 root     root        1549 Apr 24 09:09 vfstab.bak\r\n[root@test]# mv vfstab vfstab1\r\nmv: cannot rename vfstab to vfstab1: Read-only file system\r\n\r\nRebooting with command: boot\r\nBoot device: /pci@8,600000/SUNW,qlc@2/fp@0,0/disk@w21000014c3e84a61,0:a  File and args: \r\nSunOS Release 5.10 Version Generic_118822-25 64-bit\r\nCopyright 1983-2005 Sun Microsystems, Inc.  All rights reserved.\r\nUse is subject to license terms.\r\nSUNW,pci-gem0: Using Gigabit SERDES Interface\r\nSUNW,pci-gem0: Auto-Negotiated 1000 Mbps Full-Duplex Link Up\r\nHostname: test\r\n[ system/sysevent:default failed repeatedly (see \'svcs -x\' for details) ]\r\nRequesting System Maintenance Mode\r\n(See /lib/svc/share/README for more information.)\r\nConsole login service(s) cannot run\r\n\r\nRoot password for system maintenance (control-d to bypass): checking ufs filesystems\r\n/dev/rdsk/c1t0d0s4: is logging.\r\n/dev/rdsk/c1t0d0s6: is logging.\r\ncron aborted: cannot create fifo queue\r\ncron aborted: cannot create fifo queue\r\ncron aborted: cannot create fifo queue\r\nMay  8 09:53:08 svc.startd[7]: instance svc:/system/sac:default exited with status 16\r\ncron aborted: cannot create fifo queue\r\nMay  8 09:53:08 svc.startd[7]: instance svc:/system/sac:default exited with status 16\r\nMay  8 09:53:08 svc.startd[7]: instance svc:/system/sac:default exited with status 16\r\nMay  8 09:53:08 svc.startd[7]: instance svc:/system/sac:default exited with status 16\r\nMay  8 09:53:08 svc.startd[7]: instance svc:/system/sac:default exited with status 16\r\ncron aborted: cannot create fifo queue\r\nMay  8 09:53:08 svc.startd[7]: instance svc:/system/sac:default exited with status 16\r\nMay  8 09:53:08 svc.startd[7]: instance svc:/system/sac:default exited with status 16\r\nMay  8 09:53:08 svc.startd[7]: instance svc:/system/sac:default exited with status 16\r\ncron aborted: cannot create fifo queue\r\nMay  8 09:53:08 svc.startd[7]: instance svc:/system/sac:default exited with status 16\r\n[ system/sac:default failed repeatedly (see \'svcs -x\' for details) ]\r\ncron aborted: cannot create fifo queue\r\ncron aborted: cannot create fifo queue\r\ncron aborted: cannot create fifo queue\r\n[ system/cron:default failed repeatedly (see \'svcs -x\' for details) ]\r\nMay  8 09:53:10 svc.startd[7]: Could not update \"running\" snapshot for refresh of svc:/system/filesystem/autofs:default.\r\nMay  8 09:53:14 test ntpdate[532]: only 1 multicast addr can be used, exiting\r\nMay  8 09:53:14 test sendmail[498]: My unqualified host name (test) unknown; sleeping for retry\r\nMay  8 09:53:14 test sendmail[499]: My unqualified host name (test) unknown; sleeping for retry\r\nMay  8 09:54:14 test sendmail[499]: unable to qualify my own domain name (test) -- using short name\r\nMay  8 09:54:14 test sendmail[498]: unable to qualify my own domain name (test) -- using short name\r\nsupLogin incorrect\r\n\r\n[root@test]# svcs -x\r\nsvc:/application/print/server:default (LP print server)\r\nState: disabled since Tue May 08 09:52:52 2007\r\nReason: Disabled by an administrator.\r\n   See: http://sun.com/msg/SMF-8000-05\r\n   See: lpsched(1M)\r\nImpact: 2 dependent services are not running.  (Use -v for list.)\r\n\r\nsvc:/system/sysevent:default (system event notification)\r\nState: maintenance since Tue May 08 09:53:06 2007\r\nReason: Restarting too quickly.\r\n   See: http://sun.com/msg/SMF-8000-L5\r\n   See: syseventd(1M)\r\n   See: /etc/svc/volatile/system-sysevent:default.log\r\nImpact: 1 dependent service is not running.  (Use -v for list.)\r\n\r\nsvc:/system/console-login:default (Console login)\r\nState: offline since Tue May 08 09:52:51 2007\r\nReason: Unknown.\r\n   See: http://sun.com/msg/SMF-8000-AR\r\n   See: ttymon(1M)\r\nImpact: This service is not running.\r\n\r\nsvc:/system/sac:default (SAF service access controller)\r\nState: maintenance since Tue May 08 09:53:08 2007\r\nReason: Restarting too quickly.\r\n   See: http://sun.com/msg/SMF-8000-L5\r\n   See: sac(1M)\r\n   See: /etc/svc/volatile/system-sac:default.log\r\nImpact: This service is not running.\r\n\r\nsvc:/system/cron:default (clock daemon (cron))\r\nState: maintenance since Tue May 08 09:53:09 2007\r\nReason: Restarting too quickly.\r\n   See: http://sun.com/msg/SMF-8000-L5\r\n   See: cron(1M)\r\n   See: crontab(1)\r\n   See: /etc/svc/volatile/system-cron:default.log\r\nImpact: This service is not running.

\r\n\r\n谢谢你的解答。\r\nvfstab文件肯定是在/目录下，如果mount -o /的话，系统会不会启不来呀，也就是说连单用户模式都进不了，我是第一次做，谢谢你的继续答复。\r\n\r\n现在的问题就是要如何将vfstab文件中的/dev/dsk/c0t0d0s* 改为/dev/md/dsk/d*

\r\n\r\n试着boot cdrom -s了，可是提示需要输入filename，输入什么呢，试着输入vfstab，提示not found this file，输入其它也是，下一步该如何呢

mount -o remote,rw /\r\n无法做这步，总是提示/ busy

\r\n\r\n没记错的话,应该输入unix
