1441358448 M * Ghislain greeting id
1441358560 M * id i have a problem with having vservers on a zfs mount - it seems that the barrier is not set - setattr --barrier /vservers does exit with 0
1441358599 M * id but showattr is only giving ---buic- no capital B for /vservers
1441358788 M * id i am booting the whole system to ram (like a live-cd, but from pxe via a aufs3 using the latest 3.18 kernel) - first i had /vservers on aufs then i moved it to a zfs dataset

1441364623 M * daniel_hozac no
1441364632 M * daniel_hozac it's not using xattr.
1441364763 M * daniel_hozac zfs won't support any of the vserver attributes.
1441365073 M * id ok i see - can i use a loopbacked ext3/4 as parent dir for the vservers - does the barrier trigger in this kind of setup?
1441365259 M * id the root fs is on squashfs/aufs - i guess this wont work either (i tried that with the same result)
1441365362 M * daniel_hozac a zvol with ext4 should work fine.
1441365471 M * daniel_hozac i haven't looked at it too much, but you might be able to just use zfs without the barrier, as long as you make separate filesystems for each guest.
1441365486 M * id zvol is working yes - but i try to contain the basedir for the vservers on the ramdisk - if possible
1441365511 M * id ok - how can i try to escape 
1441365531 M * id is there a code bit in testfs which can be used?
1441365589 M * id or something else - maybe in the wiki? there are some code examples i saw on the barrier page - but noting i saw tested the new barrier code
1441365760 M * id thank you daniel_hozac - i will try the one guest per dataset setup
1441365833 M * id if there is something i can do for testing this kind of setup - for other ppl here too - please shout :)
1441366315 M * daniel_hozac there is a test, but i don't recall what it is.
1441366360 M * daniel_hozac as far as i can tell, it should be fine.
1441366530 M * id that would be great - thanx again - maybe Bertl has a pointer in the right direction when he comes back, how to do some testing
1441366811 M * daniel_hozac you can verify it pretty easily yourself though, just ls -li /vservers and make sure you have the same inode number for the guests' root directories.
1441367566 M * id yes - this is the case :) but i thought the barrier is a special flag which needs to be set on the parent directory - so it is not really needed when the inode is the same?
1441367751 M * id (for the guests root dirs)
1441367918 M * daniel_hozac the barrier isn't used a lot anymore. the escape it prevents is where you access the root of the filesystem by inode number.
1441367934 M * daniel_hozac the primary protection uses namespaces and pivot_root.

1441372617 M * Bertl back now ...
1441374143 M * id hi Bertl 
1441374264 M * Bertl hey, so just for the record, zfs would need a small patch to support the Linux-VServer specific flags
1441374313 M * Bertl but IIRC, it already supports flags like the immuteable attribute (not extended attributes) so that should be rather simple to add
1441374352 M * daniel_hozac now that xattrs are essentially everywhere, maybe we should look at moving the flags to one of the protected spaces there.
1441374385 M * id i guess the same would be true for squashfs/aufs
1441374839 M * Bertl daniel_hozac: yeah, I was considering that for some time, the problem is more the handling of EAs, as they are not directly associated with the inodes
