[Puppet Users] Re: Augeas editing of fstab
Yeah I've currently got a mounttab block that controls just / and /var, but
I'd kind of like to have it run on *any* filesystem that is xfs and mounted
in a VM.
This augeas works for single filesystems:
augeas { 'fstabxfsnobarrier':
context => '/files/etc/fstab/*[file="/var"][vfstype="xfs"]',
changes => [
'rm opt',
'ins opt after vfstype[last()]',
'set opt[last()] "defaults"',
'ins opt after opt[last()]',
'set opt[last()] "nobarrier"',
],
}
But if I remove the [file="/var"] then it fails.
But I do have a sort of working solution now.

If your primary interfaces are consistently named, you can create if or case statements based on the network_eth0 and netmask_eth0 facter facts. https://docs.puppetlabs.com/puppet/latest/reference/lang_conditional.html On Friday, March 20, 2015 at 11:30:20 AM UTC-4, Gary Jackson wrote: > > I'd like to use different puppetlab/firewall rules based on the subnet of > the host.

[Puppet Users] Augeas editing of fstab
Hi there,
I'm trying to add the nobarrier option to our XFS mount options in
/etc/fstab using Augeas. I've tried this:
augeas { 'fstabxfsnobarrier': context => '/files/etc/fstab', changes => [
'rm /*[vfstype="xfs"]/opt', 'ins opt after vfstype="xfs"', 'set
/*[vfstype="xfs"]/opt[last()] "defaults"', 'ins opt after vfstype="xfs"',
'set /*[vfstype="xfs"]/opt[last()] "nobarrier"', ], }
But that isn't working. Now in the past I've done something similar with
ext4 and /var, which does work:
if defined(Package['mysql55-server']) { augeas { 'fstabvarext4entry':
context => '/files/etc/fstab/*[file="/var"][vfstype="ext4"]', changes => [
'rm opt', 'ins opt after vfstype[last()]', 'set opt[last()] "defaults"',
'ins opt after opt[last()]', 'set opt[last()] "noatime"', 'ins opt after
opt[last()]', 'set opt[last()] "data"', 'set opt[last()]/value
"writeback"', 'ins opt after opt[last()]', 'set opt[last()] "barrier"',
'set opt[last()]/value "0"', 'ins opt after opt[last()]', 'set opt[last()]
"nobh"', 'ins opt after opt[last()]', 'set opt[last()] "errors"', 'set
opt[last()]/value "remount-ro"', ], } }
Can Augeas only edit one line at a time, i.e. am I not allowed to do "add
this option to every matching line"?
Any help would be greatly appreciated!
Anthony

[Puppet Users] Augeas fstab - removing all opt nodes then rebuilding
Hello All,
I have a requirement to mount /var with specific options if mysql-server is
installed and the filesystem is ext4. So far I have this:
if defined(Package['mysql55-server']) {
notice "found mysql server"
augeas { 'fstabvarentry':
context => '/files/etc/fstab/*[file="/var"][vfstype="ext4"]',
changes => [
'', # remove all opt nodes
'ins opt[1] "defaults"',
'ins opt[2] "noatime"',
# etc etc to build
"defaults,noatime,data=writeback,barrier=0,nobh,errors=remount-ro"
],
onlyif => 'match /files/etc/fstab/*[file="/var"][vfstype="ext4"]',
}
}
Now, my problem is how to deal with all possible opt entries for the /var
partition. I want to start off by removing *all* opt nodes then adding the
ones I need, but I am having trouble finding the syntax on how to remove
all opt nodes.
How can I write "rm opt*" ?
Thanks!

Re: [Puppet Users] example hiera.yaml that uses example42-network?
It was indeed an issue with the network class not being included in the
particular environment I was using.
I've remedied that now.
Just as an aside, the syntax below was correct.

[Puppet Users] example hiera.yaml that uses example42-network?
Hi All,
Does anyone use example42-network with Hiera? I'm trying to find an
example in Hiera that configures that module.
https://forge.puppetlabs.com/example42/network/readme
So far I've tried, in .yaml (Hiera works OK with hostname,
environment, etc etc)
---
network::interfaces_hash:
eth1:
ipaddress: 1.2.3.4
netmask: 255.255.0.0
gateway: 1.2.3.1
Which I think should work, based on the Puppet example from the Forge
module readme:
class { 'network': interfaces_hash =>
{ 'eth0' => { enable_dhcp => true, },
'eth1' => { ipaddress => '10.42.42.50', netmask => '255.255.255.0', },
},
}
So, any pointers on where I'm going wrong?
Thanks in advance,
Anthony
