Hi,
Just found there was a problem to mount many mounts
on FC4/FC5: total mounts can not exceed 256.
We have a bunches of machines/file-systems have to be
mounted at the same time and unfortunately the total
number of mounts exceeds 256.
The mounting commands and outputs are attached below,
newer stock kernels shows the same symptoms as well.
Please help.
[root@testMaster ~]# for i in `/axample/bin/lsng
testnode-hosts`; do echo ${i}; mount ${i}:/0
/0/ttt/${i}/0; mount ${i}:/1 /0/ttt/${i}/1; mount
${i}:/2 /0/ttt/${i}/2; mount ${i}:/3 /0/ttt/${i}/3;
done
