Timeout formatting volume

[kurtharriger]

Is there any way to increase the timeout? Looks like mkfs.ext4 is taking more than 5 minutes to format a 1000Gb ebs volume.

Hi kurtharriger

Mixlib::Shellout accepts a time out argument so there is a way. Depending on what you need, a temporary solution, a permanent solution, widespread fix or not you might try one of these.

• Add a timeout option to the lvm resource and provider.
• See https://github.com/chef/mixlib-shellout/blob/master/lib/mixlib/shellout.rb and monkey patch the timeout value.

I didn't see anything built in to the current lvm code designed to do what you want.

The workaround I came up with was to explicitly format the volume with an execute statement. lvm_logical_volume will detect that it has already been formatted and just configure fstab and mount point.

execute 'format' do
command 'yes | mkfs -t ext4 /dev/mapper/graphite-data'
not_if 'blkid -o value -s TYPE /dev/mapper/graphite-data'
timeout 1200
end

scratch that executing format explicitly only worked since the device already existed from failed run. Running on new machine failed since device had not yet been created.

I'd like to request a :timeout parameter added to certain things. In particular, the default timeout was not enough to allow mkfs.ext4 on a 15TB lv.
