problem in frecover

prasadb — Mon, 29 Dec 2008 09:54:07 GMT

hello Geeks,

i am trying to frecover a file from the tape.
i want one file i.e.,DLRTX_CLUSTER_DUMPS/DL_RTX_TAP:AUG06.dmp.Z

i m using this command :

frecover -f /dev/rmt/0mn -x -v -i /temp_for_restore/DLRTX_CLUSTER_DUMPS/DL_RTX_TAP:AUG06.dmp.Z

and following is the error i am getting.

Error

-------

msgcnt 16 vxfs: mesg 001: vx_nospace - /dev/root file system full (1 block extent)

frecover(1048): I/O error in write of file /temp_for_restore/DLRTX_CLUSTER_DUMPS/DL_RTX_TAP:AUG06.dmp.Z

-rw-r--r-- 102 104 /temp_for_restore/DLRTX_CLUSTER_DUMPS/DL_RTX_TAP:AUG06.dmp.Z

frecover(1073): frecover of DL_RTX_TAP:AUG06.dmp.Z failed

Here is the o/p of bdf command, root is not full as the error message says:

Alos, i i tried to rewind the tape and frecover.
just like,and also the error message :

# mt -f /dev/rmt/0mn rew
# frecover -f /dev/rmt/0mn -x -v -i /archive/temp_for_restore/DLRTX_CLUSTER_DUMPS/DL_RTX_TAP:AUG06.dmp.Z
frecover(4301): /archive/temp_for_restore/DLRTX_CLUSTER_DUMPS/DL_RTX_TAP:AUG06.dmp.Z not recovered from backup media

my system is HP-UX B.11.11 super-dome model

Hi Prasad,

If you /archive directory is in the root filesystem and the DL_RTX_TAP:AUG06.dmp.Z file is larger then 600MB it will fail!

Try restoring it to /var/tmp or an other filesystem with more space.

Regards,
Robert-Jan

hi,
/archive is mounted separately, its only 43 % full.

# bdf /archive
Filesystem kbytes used avail %used Mounted on
/dev/vgrtx06/lvol3 62914560 26631656 36005432 43% /archive

>Here is the output of bdf command, root is not full as the error message says:

You are confused. / was full and now it isn't. It depends on the size of the file as Robert-Jan said.

you may have a look at this thread; it is not a solution. But it may trigger some hint to you.

when i am trying to restore the files with SAM, following is the error i am getting..

"CAUTION: There is more than one user currently on the system. This
could result in an incomplete recovery if they are accessing the
files you are recovering.
Do you want to proceed? "

is the normal/frequent message while restoring ?

kindly let me know your views..

>is the normal/frequent message while restoring<

This is the normal msg, while you wil try to take backup/restore.

You will get this msg because other users are alreday loggedin in the server.
