Dear Users and Developers of Xcat
I have found a weird behaviour of the xcat in statelite mode using NFS-ROOT.
When nodes boots some files (specified in litefile table) are mounted as
tmpfs for read/write
On the compute node:
================
stat -f /etc/security/limits.conf
File: "/etc/security/limits.conf"
ID: 0 Namelen: 255 Type: tmpfs
Block size: 4096 Fundamental block size: 4096
Blocks: Total: 3082705 Free: 2927602 Available: 2927602
Inodes: Total: 3082705 Free: 3069832
However if I chroot into the image on the xcat master node and change that
file, then all the compute nodes picks up the file from nfs and the file is
not tmpfs rw any more but NFS read-only
File: "/etc/security/limits.conf"
ID: 0 Namelen: 255 Type: nfs
Block size: 32768 Fundamental block size: 32768
Blocks: Total: 36019486 Free: 35705476 Available: 33875792
Inodes: Total: 73187328 Free: 73000554
Any idea how to fix that?
