Cory and/or Ned, could you please submit a patch to resolve this issue.

[Cory Spitz]

Ned Bass was right, people who have a preexisting /etc/init.d/lustre will be in trouble.

That is unless there was already a site-specific /etc/init.d/lustre script in place and we overwrite it. The safest thing to do may be to mark it %config(noreplace) in the spec file.

That wasn't done when this landed for 2.3, so it has broken Cray's environment. (besides the other issues that Wally raised)
We can probably live with it, but maybe the Ops Manual should be updated to warn the installer.

Please reopen this ticket if there is outstanding work to do.

We have our own make/spec to build for our environment but I think you should run into the same problem using 'make rpm' in SLES11.

Hi Wally,

Thanks for reporting these problems. We knew the init scripts would probably need work to properly support non-redhat distros. I don't currently have a SLES system to test on, but when I get a chance I'll try to bring up a VM to look into this.

Are you just using 'make rpm'?

[Wally Wang (Inactive)]

When we do our packaging on SLES11 SP1/2, we run into the following problems:

1. no LSB header information:

E: File `lnet' without LSB header found in /var/tmp/cray-lustre-cray_gem_c-2.3_3.0.34_0.7.9_1.0000.6718.11.1-root/etc/init.d/
E: File `lustre' without LSB header found in /var/tmp/cray-lustre-cray_gem_c-2.3_3.0.34_0.7.9_1.0000.6718.11.1-root/etc/init.d/

2. need sysconfig.lustre in /var/adm/fillup-templates:

cray-lustre-cray_gem_c: "/etc/sysconfig/lustre" is not allowed anymore in SuSE Linux.

3. if failover is only for servers, it should probably be excluded from client build

If a site hasn't configured /etc/ldev.conf then adding the /etc/init.d/lustre script should have no effect.

That is unless there was already a site-specific /etc/init.d/lustre script in place and we overwrite it. The safest thing to do may be to mark it %config(noreplace) in the spec file.

Doug,
could you please have a look at how the patch in http://review.whamcloud.com/290 complements or conflicts with your proposed changes to LNET configuration. I believe you were already planning to start with an /etc/init.d/lnet startup file. Hopefully by landing this now, it will give you a starting point for your configuration changes, and users will already be aware of this script, so your changes will be transparent to them.
