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,
