Tru64 AdvFS transaction log



請問大家,



When you create a file system domain, AdvFS creates a transaction log file for it. During crash recovery, AdvFS reads the transaction log file to confirm file system transactions.



這裏的transaction log是指記錄這個Filesystem上所有檔案和資料的異動嗎? 還是只記錄fileset或其他架構上的異動?



謝謝

它只記錄fileset上資料的異動, And Makes an "undo" log

or file's recovered page ranges will be listed

in a log file if necessary.



See "man nvlogpg":

nvlogpg - displays domain transaction LOG.



至於Filesystem上所有檔案和資料的異動

則存於 root tag file, and fileset tag files.

nvtagpg - displays root and fileset TAG files.

感謝你的解答,

但是我執行

/sbin/advfs/nvlogpg his_db1 -d his_db1.log

會出現:

open_vol: open for volume "/dev/disk/dsk13c" failed: Device busy



其他的Domain也一樣,請問不知是否有其他方法看transaction log,或者在那裏的路徑可以看到?



謝謝

Hi,



> open_vol: open for volume "/dev/disk/dsk13c" failed: Device busy

It means the dsk13c is mounted by processes running.

Please umount it before running the command "nvlogpg" to dsk13c or the other Domains.



Best regards,

Richard.
