Problem with rdump of large filesystem on AIX 3.1.5

Problem with rdump of large filesystem on AIX 3.1.5

Post by Karen Casel » Thu, 06 Aug 1992 23:41:26



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,

1. Large filesystem support on RS/6000: AIX vs. Linux

Hey, kids!

   Just picked up a shiny new RS/6000 B50 server and a pair of 50gb SCSI
disks to go along with 'em. The original plan was to hook 'em up, along
with the internal 9gb, as a JBOD array, and export a contiguous 105gb
filesystem as a NFS repository for a bazillion code trees, multi-platform
DBMS installs, stuff like that. (We have an old NetApp NFS server...40gb,
and it's hovering neat 98% utilization).
   Here's the problem: AIX will only let you set up 2gb partitions, unless
they're "large file enabled", and then you can go up to 67mb. You can
tweak the inode settings, but that doesn't do us any good, as we store
lots and lots of teeny tiny files.
   Can Linux save the day here? Any suggestions?
