*SOLVED* OpenVZ ACL support?? [message #8352]

Hi,

I am trying to enable ACL support into a machine booted with a OpenVZ stable kernel.

I have modified /etc/fstab in VE0 (into the VEs the fstab file is empty) adding the acl option to /

Then I have remounted (even rebooted the entire machine) and when I try to setfacl:

[root@correo ~]# setfacl -m u:luis:rw- test.txt
setfacl: test.txt: Operation not supported

And in the output of dmesg:
EXT3 (no)acl options not supported

Is ACL not supported by stable kernel?

Can I rebuild the kernel with ACL support?

It is necessary because one of the VE will be a NAS attached to a Active Directory...

Thanks in advance and sorry for my poor English Sad

Luis Fernandez

Yes, just enable ACL and XATTRs in .config.
will be fixed in next build.

It works!!

Thanks for the wonderful support and for the Kernel Build guide. Here are the diff in kernel-2.6.9-023stab032-x86_64-smp.config.ovz for enable ACL in x86_64:

1199c1199,1202
< # CONFIG_EXT2_FS_XATTR is not set
---
> CONFIG_EXT2_FS_XATTR=y
> CONFIG_EXT2_FS_POSIX_ACL=y
> CONFIG_EXT2_FS_SECURITY=y
> # is not set
1202,1203c1205,1208
< # CONFIG_EXT3_FS_POSIX_ACL is not set
< # CONFIG_EXT3_FS_SECURITY is not set
---
> CONFIG_EXT3_FS_POSIX_ACL=y
> # s not set
> CONFIG_EXT3_FS_SECURITY=y
> # is not set

Cheers,
Luis Fernandez
