Frecover Errors.

aliasgar — Tue, 01 Apr 2003 05:57:17 GMT

Hello,

HP9000/K400 HPUX 10.20.

I am facing some problems when doing a frecover command ,the error is as follows
frecover -Nvx -f hpdevp_27_mar_2003.fbackup

I notice that we are getting following error.

-rwxrwxrwx runner users /home/runner/rvp.291299
-rwxr-xr-x runner users /home/runner/rvp.new
-rwxrwxrwx runner users
/home/runner/rvp.safe_jagan's_use_this_version_only
-rw-rw-rw- runner users /home/runner/rvp0.log

frecover(2104): zero length read from disk file. Frecover exiting.

he backup command:
fbackup -f /home2/backup/hpdevp.fbackup -A0uvy -g /home2/backup/backall.dat

backall.dat
systemb {root} /home/backall #cat /home2/backup/backall.dat

i /home
e /home/line3
e /home/line6
e /home/line4
e /home/line8
e /home/line5
e /home/line2
e /home/line1

2.
The backup is a disk-to-disk backup. It is a full back up.
The size of the backup file hpdevp.fbackup is about 2.1GB. I hope this is
not the problem or limitation of fbackup/frecover.
When I do frecover -f /home2/backup/hpdevp.fbackup -I lst

I get the listing of all my files. There is no problem there. However, the
actual restore and also the integrity check with -N options
fail.

I will appreciate if someone can help me out.

Thanks/Regards,
Aliasgar.

Hi,

I guess the size of the file created by fbackup was 2147483647 bytes. That is one less that 2 GB.
There seems to be a restriction in fbackup, which does not create bigger files on HPUX11.0.
You could work around the situation by directing the output to another program, which is able to handle big files. (try dd -of=xxx, | cat >xxx).

Regards, Klaus

Hi

The dd is a good idea

dd if=/dev/rmt/0m ibs=10k |frecover -x -i/dir

Do you have

PHCO_25424 s700_800 11.00 cumulative fbackup(1M)/frecover(1M) patch

on your machine

Hi,

Well according to this patch there was a limit of 4GB, you could check your system if this patch is loaded.

Hi,

Have you checked whether your filesystem supports largefiles - the default at 10.20 was nolargefiles.

Use fsadm -F to determine if you have largefiles.

Darren.
