1286474211 M * rootard Hi all, I'm trying to figure out how to run pre-start scripts to setup the filesystem mounts for a vserver. I really just want to run a few commands that are special per vserver in the host before the standard util-vserver start methods are run.
1286474215 M * rootard how do I do this?
1286474475 M * rootard I'm running debian/squeeze and util-vserver(0.30.216-pre2864-2+b1)
1286474507 M * Bertl what kind of filesystem mounts do you have in mind?
1286474623 J * petzsch ~markus@p4FF47ABE.dip.t-dialin.net
1286474858 M * rootard Bertl: I am using  unionfs and a filesystem image shared between a whole bunch of vservers
1286474916 M * rootard so I have an overlay that I maintain for each vserver and the best unionfs implementation for my needs seems to be unionfs-fuse.
1286474921 M * Bertl okay, what is the problem with mounting that in the guest's fstab?
1286474938 M * Bertl guest configs fstab to be precise
1286474941 M * rootard unionfs-fuse doesn't seem to work with an fstab
1286474962 M * Bertl what entry did you try?
1286475020 M * rootard hmm, I don't remember as it was a few weeks ago... do you think it should work?
1286475033 M * daniel_hozac yes.
1286475045 M * Bertl I think it should, but you should also know that unionfs might not be the best choice
1286475064 M * rootard why not?
1286475077 M * Bertl i.e. you end up with having separate inodes per guest, where you could save a lot of memory by using unification
1286475107 M * rootard the overhead is pretty small afaict
1286475118 M * Bertl let me explain
1286475124 M * rootard k
1286475143 M * Bertl assume you have 300M distro files
1286475162 M * Bertl and you create 100 guests from that template
1286475201 M * Bertl then without any kind of unification, you end up with 30G disk usage and a huge memory footprint
1286475223 M * Bertl now let's assume you use unionfs/fuse here
1286475239 M * Bertl about 280M are shared and identical between all guests
1286475279 M * Bertl so you end up with 2.3G disk usage, but because the filesystem is mounted for each guest, the same memory footprint as before
1286475301 M * Bertl now, if you go for a shared filesystem with what we call unification
1286475324 M * Bertl basically hard links with special addons to make them secure and CoW
1286475341 M * Bertl you end up with 2.3G disk space as well, but only a fraction of the memory footprint
1286475364 M * Bertl mainly because shared files have the same inode, get the same disk cache and page mapping when used
1286475516 M * rootard I'm a little confused because I thought unionfs was "a stackable unification file system"
1286475520 M * rootard *is
1286475602 M * Bertl it is, but caching and page mapping use per filesystem inodes
1286475603 M * rootard I like the idea of being more efficient with my shared image as it is large (but I should never have more than 6 vservers per host)
1286475627 M * Bertl so, if you mount an unionfs per guest, you get separate inodes
1286475639 M * Bertl the disk space saving will be there, but not the memory saving
1286475723 M * rootard ok, but mapping it all at the host level enables one copy of the pages of any opened file in memory
1286475751 M * Bertl that is what 'unification' is all about
1286475796 M * rootard so I think that's what I am doing currently as I setup the unionfs-fuse mounts before the vservers start. Or am I still missing something?
1286475817 M * Bertl you are missing something :)
1286475830 M * rootard ok, sorry :-/
1286475833 M * Bertl let's make it simple with an example, do you have your system at hand?
1286475838 M * rootard sure
1286475872 M * Bertl mount two separate unionfs mounts (from the same template) as you would do for two guests on different mountpoints (e.g. guest dirs)
1286475890 M * rootard ok, let's call it /mnt1 and /mnt2 
1286475895 M * Bertl then pick a shared file, i.e. one which comes from the template
1286475918 M * Bertl and now do 'stat /mnt1/file' and 'stat /mnt2/file'
1286475992 M * Bertl compare the Device: and Inode: entries
1286476004 M * rootard the inode is the same but the device is different
1286476016 M * Bertl see, so it will end up in a different cache
1286476031 M * Bertl now, take a filesystem and create a hard link like this
1286476042 M * Bertl ln /mnt/file /mnt/file2
1286476054 M * Bertl check both files again with stat
1286476077 M * rootard ok, I'm following you still... it's the same file 
1286476107 M * Bertl so it ends up with the same inode cache and memory page mapping
1286476136 M * Bertl unification and CoW link breaking (Linux-VServer filesystem features) use this to reduce disk space and memory consumption
1286476187 M * rootard aha, that's what I am missing. There is a unification layer *for vservers* that I am now aware of :)
1286476254 M * Bertl it basically utilizes hard links as you know them
1286476280 M * rootard so, I have an image and it is mounted on /mnt/src_image (for ease of discussion) as read-only ...
1286476283 M * Bertl it just adds two flags and the mechanism to execute CoW (copy on write)
1286476335 M * rootard I can't make new hard links on the filesystem so I would need to actually write to the image to use this?
1286476335 M * Bertl with unification you simply take a supported filesystem (e.g. ext2/3/4) and put your files there (single partition for all guests)
1286476359 M * Bertl then you run vunify (after simple setup described on the wiki)
1286476373 M * Bertl and it will create all the necessary hard links and flag stuff
1286476469 M * rootard so I need a read-write version of the image on each host.
1286476582 M * Bertl correct, although you could adapt unionfs to support unification and use both
1286476604 M * Bertl i.e. hard links/unification ontop of a single unionfs mount
1286476642 Q * petzsch Quit: Leaving.
1286476658 M * rootard and ensure job security ;)
1286477142 M * rootard sweet, this is something I am going to dive into and see if I can make it work for my environment. If not I'll try and poke at the fuse+fstab options again...
1286477150 M * rootard thanks for the help!
1286477291 M * Bertl you're welcome! feel free to hang around!
1286477322 M * rootard will do.
