[求助] 無法進行ufsdump or tar 到磁帶機!

coborlaw

用ufsdump / 到磁帶機 , 但會出現下列狀況.
# ufsdump 0uf /dev/rmt/12cn /
  DUMP: Writing 32 Kilobyte records
  DUMP: Date of this level 0 dump: Mon Dec 27 09:57:51 2004
  DUMP: Date of last level 0 dump: the epoch
  DUMP: Dumping /dev/md/rdsk/d1 (edmp1:/) to /dev/rmt/12cn.
  DUMP: Mapping (Pass I) [regular files]
  DUMP: Mapping (Pass II) [directories]
  DUMP: Estimated 5329268 blocks (2602.18MB).
  DUMP: Dumping (Pass III) [directories]
  DUMP: Write error 134 feet into tape 1
  DUMP: NEEDS ATTENTION: Do you want to restart?: ("yes" or "no" yes
  DUMP: Change Volumes: Mount volume `#1' on `edmp1:/dev/rmt/12cn'
  DUMP: NEEDS ATTENTION: Is the new volume (#1) mounted on `edmp1:/dev/rmt/12cn' and ready to go?:
("yes" or "no" yes
  DUMP: Dumping (Pass III) [directories]
我又換了一捲新的帶子進磁帶機!
  DUMP: Write error 134 feet into tape 1
  DUMP: NEEDS ATTENTION: Do you want to restart?: ("yes" or "no"
  DUMP: NEEDS ATTENTION: Do you want to restart?: ("yes" or "no" yes
  DUMP: Change Volumes: Mount volume `#1' on `edmp1:/dev/rmt/12cn'
  DUMP: NEEDS ATTENTION: Is the new volume (#1) mounted on `edmp1:/dev/rmt/12cn' and ready to go?:
("yes" or "no"
  DUMP: NEEDS ATTENTION: Is the new volume (#1) mounted on `edmp1:/dev/rmt/12cn' and ready to go?:
("yes" or "no" yes
我又再換了一捲新的帶子進磁帶機!
  DUMP: NEEDS ATTENTION: Cannot open `edmp1:/dev/rmt/12cn'.  Do you want to retry the open?: ("yes
" or "no" YES
帶子有防寫,退出調整後又放入!
  DUMP: Dumping (Pass III) [directories]
  DUMP: 0.08% done, finished in 0:43
  DUMP: Write error 134 feet into tape 1
  DUMP: NEEDS ATTENTION: Do you want to restart?: ("yes" or "no"
  DUMP: NEEDS ATTENTION: Do you want to restart?: ("yes" or "no" no
  DUMP: The ENTIRE dump is aborted.
最後還是卡在同一地方 >;_<

用tar /var/adm到磁帶機

# tar cvf /dev/rmt/12cn /var/adm
a /var/adm/ 0 tape blocks
a /var/adm/log/ 0 tape blocks
a /var/adm/log/asppp.log 76 tape blocks
a /var/adm/passwd/ 0 tape blocks
a /var/adm/aculog 1 tape blocks
a /var/adm/spellhist 0 tape blocks
a /var/adm/utmp 2 tape blocks
a /var/adm/utmpx 12 tape blocks
a /var/adm/wtmp 519 tape blocks
a /var/adm/wtmpx 5371 tape blocks
a /var/adm/acct/ 0 tape blocks
a /var/adm/acct/fiscal/ 0 tape blocks
a /var/adm/acct/nite/ 0 tape blocks
a /var/adm/acct/sum/ 0 tape blocks
a /var/adm/sa/ 0 tape blocks
a /var/adm/sa/sa28 15417 tape blocks
tar: write error: I/O error

最後還是出現異常!!

請教這會是什麼問題呢! 謝謝指教.

先检查一下磁带机状况，是不是该清洗了。

风之幻想

你的磁带机的clean灯是不是亮了呢。

coborlaw

最後確認是磁帶機壞了; 用clean tape cartridge清了好幾次, 仍然出現一樣的問題!

shadowmoon

不象是磁带机环,tar是不能续带的,所以先要确认要归档的东西和磁带机的容量,另外已经tar的文件即使出错也能把前面的读出来的,可以试一下

应该是磁带机有问题。/var/adm 下的文件大小应该会小于磁带容量的！

磁带机是个比较娇贵的东西，容易坏，比较烦人。
