rdump problem with aix 4.1.4 and 4.1.5

Post by Shaya Na » Fri, 06 Dec 1996 04:00:00

I have a serious problem after upgrading to 4.1.4 :
When using rdump from one machine that have 4.1.4 to another using this command :

/etc/rdump 2udsf 6250 335000 golem:/dev/rmt1.5 /dev/rhd2

I get this error message :

rdump: Date of this level 2 backup: Thu Dec  5 10:19:13 1996
rdump: Date of last level 0 backup: the epoch
rdump: Backing up /dev/rhd2 (/usr) to /dev/rmt1.5 on host golem
rdump: File system still mounted, inconsistent data possible
rdump: Mapping (Pass I) [regular files]
rdump: Mapping (Pass II) [directories]
rdump: estimated 668816 1k blocks.
rdump: Protocol to remote tape server botched (in rmtgets).
rdump: Lost connection to remote host.
rdump: Bad return code from rdump: 1

It also happen after i have upgraded to 4.1.5.

It is quite urgent so if anyone has an idea , please let me know.

Thaks in advance,



1. Problem with rdump of large filesystem on AIX 3.1.5

I am attempting to use rdump to backup a large AIX filesystem onto an Exabyte
8200 tape drive (8mm, 2.3 GB) :

Filesystem    Total KB    free %used   iused %iused Mounted on
/dev/lv00      1441792  124200   91%   44550    12% /home

I have tried the following three commands:

rdump -fdiablo:/dev/rsx0 -d 6250 -s 33000 /dev/lv00
 rdump -fdiablo:/dev/rsx0 -0 -d 6250 -s 33000 /dev/lv00
rdump -cd 43200 -s 12000 -0f diablo:/dev/rsx0 /dev/lv00

(these were recommended by my SE).  In all cases, the dump ends abnormally
after different percentages of completion, with the following message:

semop: A return value of a math subroutine is not within machine precision.

I can successfully rdump smaller file systems and I have similar problems
with another large filesystem (same size as this one).

Has anyone else encountered this problem?  Any ideas?

Thanks in advance,
