Hello everyone Management summary:
- grave bug regarding preserving volumes in last version - http://www.fluffbunny.de/setup-storage_1.4+ami.tar.gz - http://www.fluffbunny.de/testwrapper_setup-storage_2012-09-02.tar.gz As a convenience I attached the testwrapper's readme file which is also part of the archive file. Full story: I'm pretty sure I fixed the LVM troubles in setup-storage 1.4. The links are pointing to my modified version for setup-storage 1.4 which is based on package fai-setup-storage version 4.0.3+0~1346412696.57~1.gbp4b7b93 repo-url deb http://jenkins.grml.org/debian fai main A 'diff -Nur' of my patches is nearly 9kB. I tested my patched version against all tests that are currently part of my testwrapper. (I was sent quite a number of test cases, but concentrated on making Brian's md+lvm+preserve case work first.) If someone wants to jump in and provide test cases for his/her disk-configs then I'm really happy. [It's been a rough ride through s-s' internals. It was a really big relief when I enabled brian's complete testcase (reinstall+md+lvm+preserve) and it simply worked. The previous one 'reinstall+md+lvm+nopreserve' needed patching. Seems my patch regarding lvm+preserve was right on and integrated well into the general procedure.] regarding setup-storage_wrapper This wrapper is far from perfect. But for the moment it's okay. Got some ideas for improvements, which I have written down in the readme file. The thing that bugs me most is that a machine which is physically able to be configured according to the disk_config files is necessary to execute this wrapper. There are some special cases (like xen disk config and RAM dependent configs) which are a bit hard to test. (What happens if a disc is set to RAM:100% and the RAM is really large? Well setup-storage should behave like with a normal disk-config which requires more disk space then available - does it?) Someone send me a disk configuration with more then 30 disks - maybe the testwrapper could emulate/fake them by creating some loop-backed devices and feed these to setup-storage? I'm using VMware Workstation which should be able to connect up to 60 virtual scsi disks to a VM - however I don't have enough space on my personal machine for anything more then 1GB disks. (lean provisioning is no solution. mdadm plays dirty by syncing the disks.) regarding setup-storage I'm not sure how to proceed from here. Wait for Michael to come back and discuss the changes? Integrate these patches into ~experimental? Create more tests? e.g. - md on lvm (brian uses lvm on md) - encrypted volume - encrypted volume on md | lvm | md+lvm | lvm+md (or something nasty?) - 'md over lvm over md' or 'lvm over md over lvm' (I'm pretty sure there's a bug lurking here.) Why is setup-storage's version set to '1.4+ami'? I dedicate this version / these patches to Ami Suzuki which helped me immensely during debugging. (She's a japanese pop singer.) It's okay if this is renamed to 1.4.1 or 1.5 or whatever later on - I just wanted to make it apparent it's not 1.4 anymore. bye thomas P.S.: Brian? You owe me a nice cold beer or a decent chocolate. ;)
