hi,
when i started client use the method you wrote in one of your mails, i got
the result as following :(lustre1.0.4 on linux2.4.20)
[root@node20 root]# lconf --reformat --gdb --minlevel 50 --node node20
/root/lustre/etc/conf.xml
loading module: osc srcdir None devdir osc
! modprobe (error 255):> /lib/modules/2.4.20-28.9_lustre.1.0.4custom/kernel/fs/lustre/ptlrpc.o:
init_module: Input/output error> /lib/modules/2.4.20-28.9_lustre.1.0.4custom/kernel/fs/lustre/ptlrpc.o:

insmod osc failed> Hint: insmod errors can be caused by incorrect module parameters,
including invalid IO or IRQ parameters
my configure file is :
#!/bin/bash
lmc -o /root/lustre/etc/conf.xml --add net --node node20 --nid node20
--nettype tcp
lmc -m /root/lustre/etc/conf.xml --add net --node node12 --nid node12
--nettype tcp
lmc -m /root/lustre/etc/conf.xml --add net --node node17 --nid node17
--nettype tcp
lmc -m /root/lustre/etc/conf.xml --add mds --node node12 --mds mds1
--fstype ext3 --dev /tmp/mds1 --size 50000
lmc -m /root/lustre/etc/conf.xml --add lov --lov lov1 --mds mds1
--stripe_sz 65536 --stripe_cnt 0 --stripe_pattern 0
lmc -m /root/lustre/etc/conf.xml --add ost --node node17 --lov lov1 --ost
ost1 --fstype ext3 --dev /tmp/ost1 --size 10000000
lmc -m /root/lustre/etc/conf.xml --add mtpt --node node20 --path
/mnt/lustre --mds mds1 --lov lov1
and i used " lconf --maxlevel 40 " to start ost and mds in first, can
you
tell me why did that happen ? did i do something wrong?
if i use "lconf --reformat --gdb --node node20 /root/lustre/etc/conf.xml
"
to start client , sometimes i get an error:
mount failed: /mnt/lustre : mount: wrong fs type, bad option, bad
superblock on ng,
or too many mounted file systems
while sometimes it''s just ok, i don''t know why, does it need
some interval
between ost''s mds'' and client''s starting ?
thank you in advance,
YT
