Okay, so the boot system just runs mount, and then stops. What
commands to
you run inside the chroot to reproduce the problem? And what are the
expected and actual results of these commands?
I'm literally just running 'su - erikj' at this point and watching it
not work.
I have a script in our "fat initrd" miniroot that resets the test case
so I can start over quickly without rebooting. It also shows exactly
what its doing:
So the full text is:
bash-4.2# bash reset.sh
+ umount /a
+ umount /root_ro_nfs
+ umount /rootfs.rw
+ mount -o ro,noatime,nocto,actimeo=3600,lookupcache=all,nolock,tcp,vers=3
172.23.255.249:/cm_shared/image/images_ro_nfs/rhel76-aarch64-newkernel /root_ro_nfs
+ mount -t tmpfs -o mpol=interleave tmpfs /rootfs.rw
+ mkdir /rootfs.rw/upperdir
+ mkdir /rootfs.rw/work
+ mount -t overlay overlay -o
lowerdir=/root_ro_nfs,upperdir=/rootfs.rw/upperdir,workdir=/rootfs.rw/work /a
bash-4.2# chroot /a
sh: no job control in this shell
sh-4.2# su - erikj
su: warning: cannot change directory to /home/erikj: Operation not supported
su: failed to execute /bin/bash: Operation not supported
sh-4.2# exit
exit
Okay, this is very interesting. If Ganesha is running on x86_64,
then it's
less likely to be an architecture issue, and more likely to be an NFS client
version issue. What kernel version are you using on the aarch64 clients?
bash-4.2# uname -a
Linux (none) 4.14.0-115.10.1.el7a.aarch64 #1 SMP Tue Jul 30 14:50:37 UTC 2019 aarch64
aarch64 aarch64 GNU/Linux
The above is technically a centos kernel (turns out our internal aarch64
rhel76 mirror isn't working) but I had the same results with true
rhel76 GA kernel: 4.14.0-115.el7a.aarch64
I upgraded the kernel in the hopes the problem would disappear and I
could move on :) hahah
