[Bug 1212492] Re: cc_growpart broken if parted resizefs found
Ok. I'm not even sure if resizepart can be made to work, at all. $ parted --help | grep resizepart resizepart NUMBER ENDresize partition NUMBER the END seems to be in MB, which is insufficient for my needs. I'd like it to grow it to the next partition. There isn't a way to just say make it as big as possible. The undocumented flag for --script is '---pretend-input-tty', but I can't even seem to make that work. It just seems to ignore things like this: $ echo Yes | sudo parted ---pretend-input-tty /dev/vdb resizepart 1 1000 --machine --script Warning: Shrinking a partition can cause data loss, are you sure you want to continue? $ echo $? 0 but it doesn't shrink the partition table I'm going to remove the support for parted from cloud-init entirely. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to cloud-init in Ubuntu. https://bugs.launchpad.net/bugs/1212492 Title: cc_growpart broken if parted resizefs found To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1212492/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

You have to not use --script and parse the output for the warning and answer yes. I have been mulling over a --force-things system to allow a script to specify that it expects a specific error and how it should be handled but it isn't easy the way libparted is structured. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to cloud-init in Ubuntu. https://bugs.launchpad.net/bugs/1212492 Title: cc_growpart broken if parted resizefs found To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1212492/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

I dont think i follow what you meant by parse the output for the warning and answer yes.

Are you sure you want to continue? $ echo $? 1 # so that didn't resize (reading from /dev/null). Not surprising. # try with 'Yes' to stdin. echo Yes | sudo parted /dev/vdb resizepart 1; echo $? Warning: Partition /dev/vdb1 is being used.

[Bug 1212492] Re: cc_growpart broken if parted resizefs found
IIRC, parted assumes --script mode when stdin is not a tty. There was an undocumented switch that the test suite uses to override this, or I thought that expect allocates a pseudo tty (might need a switch) and that should also do the trick. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to cloud-init in Ubuntu. https://bugs.launchpad.net/bugs/1212492 Title: cc_growpart broken if parted resizefs found To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1212492/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1212492] Re: cc_growpart broken if parted resizefs found
Phillip, I guess that basically means I can't use this. :-( It also seems generally broken as the primary reason for 'resizepart' is to allow modifying a busy partition table and telling the kernel about it. Any ideas on how to proceed? Should I file a bug/feature request upstream by sending mail to bug-parted mailing list ?

Currently the only way to have parted resize a busy partition is to use interactive mode rather than script mode and say yes at the prompt. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to cloud-init in Ubuntu. https://bugs.launchpad.net/bugs/1212492 Title: cc_growpart broken if parted resizefs found To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1212492/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
