Is XFS file system secure? [message #2141]

Hello,

I have a security related question: Is there any (security related) reason against the use of XFS as filesystem for /vz? Am I able to use all openvz functions when I use XFS as filesystem for /vz? I ask this because XFS is much faster than ext3 but it is not included into the standard (stable) openvz kernel.

ehhh... There is no any security issues with it. But one problem I forsee actually. XFS uses itw own quota implementation (non linux), so I think it won't work with OVZ quota without some efforts.

Why do you think XFS is faster than ext3? Do you have you benchmarks? Just curious.

Well...
We did a benchmark with ext3 and XFS. We did not use a benchmark tool but real users that surf through a website and call different SQL queries. Queries on MyISAM tables were slower when using ext3. The database is quite big (about 20GB at the moment) therefore the file system has to do a lot of work. We think that XFS is about 10% to 20% faster than ext3 for the same system load.

I think we need quota on that server. Therefore I think we can use XFS.

Thank you!

yes, XFS is very fast and powerful (SGI use it over 10 years if I'm right Wink

)

For instance this article shows it good:

Filesystems (ext3, reiser, xfs, jfs) comparison on Debian Etch
http://www.debian-administration.org/articles/388

(It is linked on the first article of a nice german article about high availabilty clustering with OpenVZ, DRBD and heartbeat: http://www.pro-linux.de/work/virtual-ha/ )

I must agree that XFS does a really great job with the VEs (performance +++). As mentioned previously, the only thing that isn't working is the quota.

Also, XFS permit us to do live modifications to the FS without the need to stop all VEs (compared to ext3).

Are they any plans to make OpenVZ runs with XFS support? That would be a big must for the tool adoption in my opinion.
