[chef] weird issue with provider condition evaluations...

[Jeremy Winters < >]

below is a truncated example of our provider that allows us to create volumes that may or may not be block encrypted.

this is iterated in the recipe across several volumes... /dev/sdr, /dev/sqs... etc.

what we're seeing is that the when it runs for the first volume... everything works great... but the value for our device variable, which should be recalculated for each volume (as each volume is a separate resource call) is not being updated.

so.. the check for xfs volume /dev/sdr would look like...

xfs_admin -l /dev/sdr 2>&1 | grep 'unexpected XFS SB magic number'

...but when the check is executed for /dev/sds.. it is running...

xfs_admin -l /dev/sdr 2>&1 | grep 'unexpected XFS SB magic number'

...when it should be running...

xfs_admin -l /dev/sds 2>&1 | grep 'unexpected XFS SB magic number'

this worked for us in chef 0.9... but in 0.10 we are now seeing this issue where the local device variable seems to not get updated with subsequent resource calls.

any ideas?

thanks in advance!

here is our provider code...

----------------------------

action :create do

        device = ""   

        #if crypto_passphrase is not nil, set up encryption

        if new_resource.crypto_passphrase   

...do all the encryption stuff...

            device = dev_mapper

        elsif

            device = new_resource.device

        end

        #if volume is blank then format it as new_resource filesystem

        execute "create_#{new_resource.file_system}_volume" do

            command "mkfs.#{new_resource.file_system} #{device}"

            action :run

            only_if "xfs_admin -l #{device} 2>&1 | grep 'unexpected XFS SB magic number'" if new_resource.file_system == "xfs"

            only_if "tunefs2 -l  #{device} 2>&1 | grep 'Bad magic number in super-block'" if new_resource.file_system == "ext3"

        end

end
